Refer to the complete mechanical drawings and notes when planning installation. Model and DC Input Ratings Complete order code ERG-5000H-T DC input connection Terminal block Independent DC input channels 4 Typical rated DC input power 5000 W Typical maximum DC input power 6000 W Typical rated input power per channel 1250 W Typical maximum input power per channel 1500 W DC input voltage range 60–420 VDC Typical rated input current per channel 21 A Typical maximum input current per channel 25 A This model uses the 60–420 VDC input range selected by H in the order code. The -T suffix selects terminal-block DC inputs. The four-channel rated input is 1250 W × 4, and the typical maximum is 1500 W × 4. The maximum 6000 W capability automatically derates toward rated power as ambient temperature rises; over-temperature protection operates if the internal temperature limit is exceeded. No fixed maximum-power duration is specified. Observe voltage, current, total-power and temperature limits together. Maximum current and maximum voltage are not an unrestricted simultaneous operating point. This product absorbs DC energy from equipment under test and returns energy to the AC utility. AC Grid Return and Efficiency Typical rated AC output apparent power 4500–4600 VA at 60–420 VDC input AC grid voltage 180–264 VAC, with the stated ±5 VAC tolerance AC connection Single phase AC frequency range 47–63 Hz Typical maximum AC output current 24 A at 230 VAC Power factor at rated power >0.97 Typical THD at rated power <5% Typical conversion efficiency 91% at 380 VDC input and 5000 W input power Typical energy recycling ratio 88% at 380 VDC input and 5000 W input power The recycling-ratio reference assumes that the source power supply has at least 96.5% efficiency. System energy recycling ratio equals source power-supply efficiency multiplied by ERG conversion efficiency; it is not the ERG efficiency alone. Unless otherwise stated, specifications are measured at 230 VAC output, 380 VDC input, rated input power and 25°C ambient. The efficiency and recycling plots use the same DC voltage and 25°C, with 100% load defined as 5000 W. The plots illustrate changes with load rather than a constant efficiency guarantee. The AC power figures are stated in VA. The 5000 W and 6000 W figures above describe DC input power, not a promise of that amount of AC output. Connect the AC output to a compatible utility system and protective earth as shown in the connection diagram. Operating Modes and CANBus Control Constant-current setting range 0.1–25 A ±1% Constant-voltage setting range 60–420 VDC ±1% Communication interface CANBus CANBus baud rate 250 kbps Maximum system unit count 64 CANBus address switches SW51 and SW52 CC means constant-current operation and CV means constant-voltage operation. Current-setting tolerance is based on maximum input current; voltage-setting tolerance is based on maximum input voltage. Tolerance can increase at ambient-temperature extremes. Use the MEAN WELL CMU2A controller or a suitable CANBus interface for remote setting, monitoring and data analysis. Select the controller configuration for the ERG application; it is separate equipment in the system diagram. Follow the manufacturer’s user manual for addressing, commands and system setup. JK1 provides two linked eight-position CANBus sockets. Use twisted-pair communication wiring. After connecting the communication cable, fit termination resistors to the remaining end sockets of both the ERG system and CMU2A to suppress signal reflections. The controller’s separate power input shown in the system diagram is not an additional ERG input rating.

DC Input Connections DC input channels CH1, CH2, CH3 and CH4 DC terminal polarity Each channel has a separately marked +V and −V connection The front drawing shows four terminal-block channel connections. Observe the individual +V and −V markings and select leads for the actual current and installation. The NEWSOK numbered-contact table and connector leads apply to the NEWSOK construction, not this -T terminal-block version. Channel and System Configurations Four channels in parallel: connect the four channels to one suitable source as shown in the front-panel wiring diagram. Two independent groups: each source uses a pair of channels, giving a rated input allocation of 1250 W × 2 per group. Four independent channels: connect up to four separate units under test to the four channel pairs. A single ERG can use four channels in series, or two sets of two channels in series, following the two separate diagrams. Multiple ERG units can be arranged in the illustrated series/parallel systems, up to 64 units. This system count does not override channel voltage, current, power, insulation or control limits. Follow the manufacturer’s diagrams and user manual for the selected arrangement. Select suitable wires between the power supplies under test and the ERG to reduce line loss and improve energy recycling. Verify polarity and the complete interconnection before enabling the system.

AC Grid Return and Efficiency Typical rated AC output apparent power 2600–4320 VA at 10–12 VDC input; 4320–4400 VA at 12–60 VDC input AC grid voltage 180–264 VAC, with the stated ±5 VAC tolerance AC connection Single phase AC frequency range 47–63 Hz Typical maximum AC output current 24 A at 230 VAC Power factor at rated power >0.97 Typical THD at rated power <5% Typical conversion efficiency 88% at 48 VDC input and 5000 W input power Typical energy recycling ratio 80% at 48 VDC input and 5000 W input power The recycling-ratio reference assumes that the source power supply has at least 90.5% efficiency. System energy recycling ratio equals source power-supply efficiency multiplied by ERG conversion efficiency; it is not the ERG efficiency alone. Unless otherwise stated, specifications are measured at 230 VAC output, 48 VDC input, rated input power and 25°C ambient. The efficiency and recycling plots use the same DC voltage and 25°C, with 100% load defined as 5000 W. The plots illustrate changes with load rather than a constant efficiency guarantee. The AC power figures are stated in VA. The 5000 W and 6000 W figures above describe DC input power, not a promise of that amount of AC output. Connect the AC output to a compatible utility system and protective earth as shown in the connection diagram. Operating Modes and CANBus Control Constant-current setting range 0.5–125 A ±1% Constant-voltage setting range 10–60 VDC ±1% Communication interface CANBus CANBus baud rate 250 kbps Maximum system unit count 64 CANBus address switches SW51 and SW52 CC means constant-current operation and CV means constant-voltage operation. Current-setting tolerance is based on maximum input current; voltage-setting tolerance is based on maximum input voltage. Tolerance can increase at ambient-temperature extremes. Use the MEAN WELL CMU2A controller or a suitable CANBus interface for remote setting, monitoring and data analysis. Select the controller configuration for the ERG application; it is separate equipment in the system diagram. Follow the manufacturer’s user manual for addressing, commands and system setup. JK1 provides two linked eight-position CANBus sockets. Use twisted-pair communication wiring. After connecting the communication cable, fit termination resistors to the remaining end sockets of both the ERG system and CMU2A to suppress signal reflections. The controller’s separate power input shown in the system diagram is not an additional ERG input rating.

Channel and System Configurations Four channels in parallel: connect the four channels to one suitable source as shown in the front-panel wiring diagram. Two independent groups: each source uses a pair of channels, giving a rated input allocation of 1250 W × 2 per group. Four independent channels: connect up to four separate units under test to the four channel pairs. A single ERG can use four channels in series, or two sets of two channels in series, following the two separate diagrams. Multiple ERG units can be arranged in the illustrated series/parallel systems, up to 64 units. This system count does not override channel voltage, current, power, insulation or control limits. Follow the manufacturer’s diagrams and user manual for the selected arrangement. Select suitable wires between the power supplies under test and the ERG to reduce line loss and improve energy recycling. Verify polarity and the complete interconnection before enabling the system.

It accepts 60–380 VDC and returns recovered energy through a 320 VDC output. The typical rated input reaches 1440 W in the 100–380 VDC range, with reduced input-power capability below that range. This model provides CC/CV control, internal fan cooling and built-in CANBus communication. Product Datasheet Download MEAN WELL ERS-1400 Datasheet (PDF) The ERS-1400 section is on PDF pages 1, 2, 3, 4, 5, 6, 7. Refer to the complete mechanical drawings and notes when planning installation. Model and DC Energy-Recovery Ratings Complete order number ERS-1400H Series ERS-1400 Input channels 4 DC input voltage range 60–380 VDC Maximum typical DC input power 1440 W Typical input power below the full-power range 864–1440 W at 60–100 VDC Typical rated input current 3.6 A per channel × 4 channels DC output voltage 320 VDC DC output voltage tolerance ±2% Maximum DC output current 6.3 A Maximum output ripple and noise 4 V The 1440 W typical rated input applies at 100–380 VDC. Input voltage, channel current and combined input power must all remain within their applicable limits. The recovered 320 VDC output is shown feeding the input of suitable equipment under test in the burn-in system. Use equipment and wiring rated for that recovery connection; the separately listed maximum output current is not an additional rated-output-power allowance. Unless otherwise stated, ratings are measured at 320 VDC output, 380 VDC input, rated input power and 25°C ambient. Control Modes and Input-Power Curve Constant-current setting per channel 0.5–3.6 A, ±1% Available control modes CC/CV Constant-voltage setting 60–380 VDC, ±10 V Select constant-current or constant-voltage operation for this H version. Match every connected source to its voltage range and limit the combined channel input to the permitted total power. The static-characteristic curve marks 60% input power at 60 VDC, rising to 100% at 100 VDC and remaining at 100% through 380 VDC. Control tolerances are calculated from maximum input current and maximum input voltage. Tolerances can increase at high and low ambient temperatures. Efficiency and AC Auxiliary Input Typical conversion efficiency 90% at 380 VDC input Typical energy recycling ratio 85% AC input voltage range 180–264 VAC AC input frequency 47–63 Hz Power factor 0.97 at 230 VAC Typical AC inrush current 50 A at 230 VAC The 85% recycling example is specified at 380 VDC input and 1440 W with the power supply under test operating at an efficiency of at least 96%. System energy recycling ratio is calculated as the efficiency of the power supply under test multiplied by the ERS unit efficiency. Wiring losses and the operating point affect the achieved result. The efficiency-versus-load plot is measured at 380 VDC input and 25°C. Use the plotted load dependence for system assessment; the typical efficiency is not a guarantee at every load. Connect the rear AC inlet to L, N and protective earth as shown in the wiring diagram. The 180–264 VAC rating belongs to the ERS unit; the separate CMU2A supply shown in the system drawing is rated 90–264 VAC.
