The Preen ADGP400125 Programmable High Power DC Power Supply, 400V/125A, 50kW features a high power density, high output power, low noise, and tight regulation. The combination of DSP and PWM technologies has enabled significant advances in stability and measurements. Designed for the increasing demand of high power DC, the ADG-P-400-125 is ideal for testing EV's motor/compressor, server power supply, fuse/circuit breaker/contactor, and PV inverter or can be used as a facility power or EMC chamber power. The STEP and GRADUAL modes allow easy setup on test sequence and depending on CV/CC settings and load conditions, the ADGP400125 can operate as a current or voltage source.

This model includes multiple levels of protection to safeguard the device. These include over-voltage, overcurrent, over-power, over-temperature, and input under/overvoltage to shut down the power supply output to prevent fault conditions and further damages. Its remote sensing feature can effectively reduce voltage drop caused by cable length and provides more flexibility on installation. The included RS-485 interface allows the user to easily program the unit through different interfaces or Preen's control software.
