General test conditions Normal input voltage, rated load, +25°C and 70% RH ambient, except where a specific condition is stated

Control, protection and alternative connection

Remote ON/OFF Voltage is measured from R.C. to COM. ON: 1.2 V DC < R.C.–COM < 12 V DC, or an open circuit. OFF: R.C.–COM < 0.4 V DC, or a short circuit. The pin table assigns R.C. to pin 13 and COM to pins 5, 6, 7 and 8.
Remote-control pin-reference difference The remote-control sentence on PDF page 10 refers to pins 5, 6 and 11, while the 13-pin configuration table on page 12 assigns COM to pins 5–8, pin 11 to N.C., and pin 13 to R.C. Confirm the supplied unit and the applicable pin diagram with MEAN WELL before wiring; do not treat pin 11 as R.C. solely from that parenthetical sentence.
Optional output trim Pin 12 is Trim (optional). Confirm the supplied trim configuration and allowable adjustment range before use; the series pages do not specify a trim range or external adjustment-resistor value.
Overload protection 120–300% of rated output power, typical; hiccup mode with automatic recovery after the fault condition is removed
Short-circuit protection All outputs have short-circuit protection; hiccup mode with automatic recovery after the fault condition is removed
Overvoltage protection 6.4–7.5 V; shuts off the output voltage and clamps it with a TVS diode
Input fuse recommendation 8 A fuse, as recommended in the input specification
Negative-output connection reference The negative-output diagram connects the external positive supply to module +Vin pins 9 and 10; external −Vin and the application GND connect to module +Vout pins 1–4; the negative output −Vo is taken from COM pins 5, 6, 7 and 8. The input capacitor is positive toward external +Vin; the output capacitor is positive toward application GND. PDF page 11 notes an input-voltage difference without specifying a separate negative-output input range. The external supply reference in this connection differs from module COM. Confirm the complete negative-output application limits and control references with MEAN WELL; the diagram does not provide a separate negative-output current or power rating.

Environment and load derating

Operating temperature and cooling −30 to +85°C, subject to the derating curves; cooling by free-air convection
Input-dependent load derating Vertical installation, free-air convection. For 10.5 ≤ Vin ≤ 30 V DC, the curve permits 100% load through +50°C, about 75% at +65°C, 60% at +75°C and 40% at +85°C. For 30 < Vin ≤ 48 V DC, the corresponding limits are 90% through +50°C, about 65% at +65°C, 50% at +75°C and 30% at +85°C. Follow the applicable input-voltage curve between these points; +85°C is the working-temperature limit.
Working humidity 20–85% RH, non-condensing
Storage temperature −30 to +105°C
Temperature coefficient ±0.03%/°C over 0 to +50°C
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes

Mechanical details and packing

Safety, EMC and reliability

Safety standards EAC TP TC 004 approved; BS EN/EN 62368-1 (LVD) is listed in the safety specification
Conducted and radiated emissions BS EN/EN 55032 Class A without additional EMC components; Class B with the specified external EMC filter components
EMC suggestion circuit components C1 and C2: 120 µF / 63 V each; C3: 22 µF / 35 V. The L1 table on PDF page 12 literally prints 15 µF (NiZn), although L1 is drawn as a coupled inductor. Obtain the correct inductance/unit and applicable component specification from MEAN WELL before implementing the Class B filter; do not use the printed capacitance unit as an inductor specification.
EMC suggestion circuit connections L1 has coupled windings in both input conductors. C1 is across the input before L1, and C2 is across the module input after L1, with their positive terminals toward +Vin. C3 is across +Vo and −Vo, positive toward +Vo. Module GND, the filtered input return and output −Vo share the common node in this positive-output EMC example.
