Unless specified otherwise, measurements are at delta 230 VAC (Y 400 VAC), rated load and 25°C ambient. Tolerance includes setup, line and load regulation. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated by parallel 0.1 uF and 47 uF capacitors.

AC Connections and Terminal Assignments

TB1 input pins 1: AC/L1; 2: AC/N1; 3: AC/L2; 4: AC/N2; 5: AC/L3; 6: AC/N3. Maximum mounting torque 18 kgf-cm.
Three-phase delta, Figure 1.1 196 to 305 VAC line-to-line: connect phase R to L1 and N3, S to L2 and N1, T to L3 and N2. Connect FG to protective earth as shown.
Three-phase star, Figure 1.2 340 to 530 VAC line-to-line: R to L1, S to L2, T to L3; connect the neutral to N1, N2 and N3. The figure shows 196 to 305 VAC phase-to-neutral. Connect FG to protective earth.
Single-phase alternative, Figure 1.3 196 to 305 VAC, 2-wire: connect L to L1/L2/L3 and N to N1/N2/N3; connect FG to protective earth.

Use the complete connection diagrams and terminal markings. The single-phase alternative is explicitly permitted, but characteristics can differ from the three-phase specification, including greater ripple/noise; consult MEAN WELL for application issues. Do not apply the 340 to 530 VAC line-to-line range to an individual L-N branch.

Protection and DIP-Switch Modes

Overload threshold 100% to 112% of rated output power. Short-circuit and fan-failure protection/alarm are also listed.
DIP 1 OFF: continuous current mode Continuous constant-current operation under overload is specified only while output voltage is greater than 50% of rated output voltage.
DIP 1 ON: delayed shutdown Overload or short circuit causes shutdown after 5 seconds of constant-current operation; re-power to recover.
Over-voltage protection 60 to 67.2 V; output shuts down, re-power to recover.
Over-temperature protection Output shuts down and automatically recovers after temperature decreases.
DIP 2: current selection OFF selects the default overload/current value; ON enables external constant-current-level programming.
DIP 3: voltage selection OFF selects built-in potentiometer adjustment; ON enables external output-voltage programming.

The mechanical assignment illustration shows all three DIP positions OFF. Use each function diagram and the actual switch markings to select the required mode. Do not extend continuous constant-current operation below the stated 50%-voltage condition.

Voltage and Current Programming

PV wiring / allowed range With DIP 3 ON, apply external DC voltage between PV+ and PV- on CN313 or CN314: pin 6 PV+, pin 4 PV-. Output can be programmed from 20% to 120% of nominal voltage.
PV graph anchors 1 V external corresponds to 20% output, 5 V to 100%, and 6 V to 120%. The diagram labels the relationship Non-Linear; use the plotted range rather than extrapolating beyond it.
PC wiring / allowed range With DIP 2 ON, apply external DC voltage between PC+ and PC- on CN313 or CN314: pin 9 PC+, pin 7 PC-. Constant-current level can be programmed from 20% to 100% of rated current.
PC graph anchors 1 V external corresponds to 20% current and 5 V to 100%. The diagram is labeled Non-Linear; do not infer operation outside the stated range.
Light-load voltage adjustment caution Trimming PV from a high to a lower setting at light/no load can trigger floating over-voltage protection. The manufacturer suggests turning the supply OFF, setting PV to its lowest level, then adjusting output to the desired value.

The programming diagrams retain the factory +S-to-+V and -S-to--V links. Follow the remote-sense instructions if using remote sensing. Programming ranges do not authorize exceeding this model's rated power or applicable thermal limits.

Remote Sense, Remote Control and Auxiliary Power

Remote-sense wiring CN313/CN314 pin 3 +S to load positive and pin 5 -S to load negative; twist the sense pair. Maximum load-cable voltage-drop compensation is 0.3 V.
Local-sense factory links When remote sense is unused, +S must connect to +V and -S to -V to avoid noise/interference. These links are stated as factory default.
Remote ON/OFF wiring Connect CN313/CN314 pin 8 RC- to CN315 pin 3 GND-AUX. A switch between pin 10 RC+ and CN315 pin 1 12V-AUX gives ON when shorted, OFF when open.
12 V auxiliary output CN315 pin 1, referenced to pin 3 GND-AUX: 11.4 to 12.6 V, maximum 0.1 A. It is not controlled by remote ON/OFF; the specification restricts this auxiliary to remote ON/OFF control.
Signal grounds / load terminals GND-AUX is isolated from main +V/-V. CN315 pin 5 +V(signal) and pin 7 -V(signal) are for local sense only and must not be directly connected as load power terminals.

CN313 and CN314 Control Pins

Pins 1 / 2 1: CS-; 2: CS+, current-sharing signals. Join corresponding CS pins when paralleling units.
Pins 3 / 5 3: +S; 5: -S, remote sensing.
Pins 4 / 6 4: PV-; 6: PV+, voltage programming.
Pins 7 / 9 7: PC-; 9: PC+, current programming.
Pins 8 / 10 8: RC-; 10: RC+, remote ON/OFF.
Connector / mating housing CN313 and CN314: HRS DF11-10DP-2DS / HRS DF11-10DS, or equivalents; the two connectors are internally connected.

The drawing shows even pins 10 to 2 on one row and odd pins 9 to 1 on the other. Follow the actual connector orientation, not a mirrored cable view.

CN315 Auxiliary and Alarm Pins

Auxiliary / local-sense pins 1: 12V-AUX; 3: GND-AUX; 5: +V(signal); 7: -V(signal).
DC-OK open collector Pin 4 DC-OK2 with pin 2 DC-OK2-GND: LOW when the power supply turns ON.
AC-fail open collector Pin 8 AC-FAIL2 with pin 6 AC-FAIL2-GND: LOW when input voltage is too low.
Temperature / fan open collectors Pin 9 OTP2 with pin 11 OTP2-GND: LOW on over-temperature protection. Pin 10 FAN-FAIL2 with pin 12 FAN-FAIL2-GND: LOW on internal fan failure.
DC-OK relay Pin 14 DC-OK1 with pin 16 DC-OK1-GND: normally open, closes when the supply turns ON.
AC-fail relay Pin 19 AC-FAIL1 with pin 17 AC-FAIL1-GND: normally open, closes when input voltage is too low.
Temperature / fan relays Pin 13 OTP1 with pin 15 OTP1-GND: normally open, closes on over-temperature protection. Pin 20 FAN-FAIL1 with pin 18 FAN-FAIL1-GND: normally open, closes on internal fan failure.
Connector / mating housing CN315: HRS DF11-20DP-2DS / HRS DF11-20DS, or equivalents.

Each of the four signals offers relay-contact and open-collector outputs. Relay contacts are rated at maximum 30 V / 1 A resistive. Open collectors are isolated from the main output and require an external voltage source: maximum 20 V and 10 mA sink current; the internal 24 V Zener does not raise the permitted external voltage.

The example uses four 10 kΩ pull-up resistors with the 12 V auxiliary and shows the relevant return connections. These are circuit examples, not included accessory quantities. Follow the per-signal states above: DC-OK closes/goes LOW during normal ON operation; the fault signals activate on their respective faults.

Current Sharing and Wiring Limits

Parallel limit / current equation Up to four units. Maximum total current = rated current per unit x number of units x 0.9; this model's rated current is 105 A.
Voltage matching / low-load behavior Match outputs to less than 0.2 V difference. Below 5% of total rated current, current sharing may not be fully balanced.
Signal / sense wiring Interconnect corresponding +S/-S, CS+/CS- and RC+/RC- as illustrated. When using remote sense in parallel, connect the load-sensing wires only to the master unit.
Sense-wire separation Keep remote-sense wiring at least 30 cm from input wiring. Use the complete parallel diagram for master and inter-unit connections.

The family headline states up to 20000 W (3+1); it does not override the current equation or the individual model's actual wattage and thermal limits. Do not connect every unit's sense pair independently to the load.

Temperature, Environment and Derating

Operating range / thermal curve -30°C to +70°C. Horizontal curve: full load through 50°C, declining to 50% at 70°C.
Static input characteristic At 60 Hz, the curve shows 100% load across delta 196 to 305 VAC / Y 340 to 530 VAC. Use the documented connection and thermal conditions.
Cooling / indicators Built-in DC fans with fan-speed control. Green LED1: output voltage OK. Red LED2: protection has occurred.
Working / storage humidity Working 20% to 90% RH non-condensing. Storage -40°C to +85°C, 10% to 95% RH non-condensing.
Temperature coefficient / vibration ±0.03%/°C over 0°C to 50°C. 10 to 500 Hz, 2 G, 10 minutes/cycle, 60 minutes each along X, Y and Z.
Altitude derating For this fan-cooled model, reduce allowable ambient temperature by 5°C per 1000 m above 2000 m.

The 48 V efficiency graph compares delta 230 VAC and Y 400 VAC and prints 90.59% and 90.76% respectively; these curve annotations are distinct from the 91.5% typical specification-table value. Do not transfer that curve to the 24 V or 36 V model. The pages do not specify a maximum operating altitude or a precise fan-speed/temperature law.

    Voltage and Current Programming

    PV wiring / allowed range With DIP 3 ON, apply external DC voltage between PV+ and PV- on CN313 or CN314: pin 6 PV+, pin 4 PV-. Output can be programmed from 20% to 120% of nominal voltage.
    PV graph anchors 1 V external corresponds to 20% output, 5 V to 100%, and 6 V to 120%. The diagram labels the relationship Non-Linear; use the plotted range rather than extrapolating beyond it.
    PC wiring / allowed range With DIP 2 ON, apply external DC voltage between PC+ and PC- on CN313 or CN314: pin 9 PC+, pin 7 PC-. Constant-current level can be programmed from 20% to 100% of rated current.
    PC graph anchors 1 V external corresponds to 20% current and 5 V to 100%. The diagram is labeled Non-Linear; do not infer operation outside the stated range.
    Light-load voltage adjustment caution Trimming PV from a high to a lower setting at light/no load can trigger floating over-voltage protection. The manufacturer suggests turning the supply OFF, setting PV to its lowest level, then adjusting output to the desired value.

    The programming diagrams retain the factory +S-to-+V and -S-to--V links. Follow the remote-sense instructions if using remote sensing. Programming ranges do not authorize exceeding this model's rated power or applicable thermal limits.

    Remote Sense, Remote Control and Auxiliary Power

    Remote-sense wiring CN313/CN314 pin 3 +S to load positive and pin 5 -S to load negative; twist the sense pair. Maximum load-cable voltage-drop compensation is 0.3 V.
    Local-sense factory links When remote sense is unused, +S must connect to +V and -S to -V to avoid noise/interference. These links are stated as factory default.
    Remote ON/OFF wiring Connect CN313/CN314 pin 8 RC- to CN315 pin 3 GND-AUX. A switch between pin 10 RC+ and CN315 pin 1 12V-AUX gives ON when shorted, OFF when open.
    12 V auxiliary output CN315 pin 1, referenced to pin 3 GND-AUX: 11.4 to 12.6 V, maximum 0.1 A. It is not controlled by remote ON/OFF; the specification restricts this auxiliary to remote ON/OFF control.
    Signal grounds / load terminals GND-AUX is isolated from main +V/-V. CN315 pin 5 +V(signal) and pin 7 -V(signal) are for local sense only and must not be directly connected as load power terminals.

    Connector / mating housing CN315: HRS DF11-20DP-2DS / HRS DF11-20DS, or equivalents.

    Each of the four signals offers relay-contact and open-collector outputs. Relay contacts are rated at maximum 30 V / 1 A resistive. Open collectors are isolated from the main output and require an external voltage source: maximum 20 V and 10 mA sink current; the internal 24 V Zener does not raise the permitted external voltage.

    The example uses four 10 kΩ pull-up resistors with the 12 V auxiliary and shows the relevant return connections. These are circuit examples, not included accessory quantities. Follow the per-signal states above: DC-OK closes/goes LOW during normal ON operation; the fault signals activate on their respective faults.

    Current Sharing and Wiring Limits

    Parallel limit / current equation Up to four units. Maximum total current = rated current per unit x number of units x 0.9; this model's rated current is 105 A.
    Voltage matching / low-load behavior Match outputs to less than 0.2 V difference. Below 5% of total rated current, current sharing may not be fully balanced.
    Signal / sense wiring Interconnect corresponding +S/-S, CS+/CS- and RC+/RC- as illustrated. When using remote sense in parallel, connect the load-sensing wires only to the master unit.
    Sense-wire separation Keep remote-sense wiring at least 30 cm from input wiring. Use the complete parallel diagram for master and inter-unit connections.

    The family headline states up to 20000 W (3+1); it does not override the current equation or the individual model's actual wattage and thermal limits. Do not connect every unit's sense pair independently to the load.

    Temperature, Environment and Derating

    Operating range / thermal curve -30°C to +70°C. Horizontal curve: full load through 50°C, declining to 50% at 70°C.
    Static input characteristic At 60 Hz, the curve shows 100% load across delta 196 to 305 VAC / Y 340 to 530 VAC. Use the documented connection and thermal conditions.
    Cooling / indicators Built-in DC fans with fan-speed control. Green LED1: output voltage OK. Red LED2: protection has occurred.
    Working / storage humidity Working 20% to 90% RH non-condensing. Storage -40°C to +85°C, 10% to 95% RH non-condensing.
    Temperature coefficient / vibration ±0.03%/°C over 0°C to 50°C. 10 to 500 Hz, 2 G, 10 minutes/cycle, 60 minutes each along X, Y and Z.
    Altitude derating For this fan-cooled model, reduce allowable ambient temperature by 5°C per 1000 m above 2000 m.

    The 48 V efficiency graph compares delta 230 VAC and Y 400 VAC and prints 90.59% and 90.76% respectively; these curve annotations are distinct from the 91.5% typical specification-table value. Do not transfer that curve to the 24 V or 36 V model. The pages do not specify a maximum operating altitude or a precise fan-speed/temperature law.

    Mounting dimensions Longitudinal fixing span 399 mm; side fixing vertical span 38 mm; main-face transverse fixing span 120 mm. Refer to the complete drawing for offsets, including 29.9, 22.7 and 45.5 mm.
    Terminal geometry Output projection is marked 38 mm, with 8.5 mm holes and 2-M3 callout. TB1 input projection is 18 mm maximum; 10 and 13 mm are terminal drawing dimensions, not both assumed pitch.
    Airflow / adjustments Keep the illustrated airflow from the terminal side toward the fan side unobstructed. The drawing identifies SVR, DIP-SW, LED1, LED2, CN313/CN314/CN315 and screw A.
    Dielectric-test screw instruction For withstand-voltage and insulation-resistance testing, temporarily remove screw A and reinstall it after testing, as explicitly instructed.
    Mating contact family Both connector sizes list HRS DF11-**SC or equivalent. The wildcard is not a complete orderable terminal suffix; select the exact contact for the wire and housing.

    The mating housings above are documented compatible connection parts; the pages do not specify included cable/housing quantities or a complete harness product code. No output-terminal torque or wire-gauge value is supplied here. Consult the full drawing and manufacturer installation manual; do not import another series' hardware limits.
