7.5 kW Bidirectional Programmable DC Power Supply - Regenerative Source/Sink for Battery and PV Test
XGY N351 is designed for tests that need current to flow both from the supply to the DUT and from the DUT back to the grid. Regenerative operation can reduce heat dissipation and improve test-system efficiency.
Key technical parameters for the N351 Bidirectional Programmable DC Power Supply.
40 V / 80 V
+/-55 A to +/-300 A by model
Up to 7500 W is integrated in a 1U chassis for compact systems.
LAN, RS232, RS485, and CAN are standard, with Modbus-RTU, CANopen, and SCPI protocol support.
Application fit
Power products are rarely selected from one headline rating. The useful shortlist starts with the electrical envelope, DUT role, control interface and acceptance evidence.
