EA-PUB 10360-480 6U WC Programmable Bidirectional DC Power Supply with Water Cooling

The EA-PUB 10360-480 6U WC is a high-power, programmable, bidirectional DC power unit capable of functioning as both a precision power source and a regenerative electronic load. In sink (load) mode, it recovers energy with an efficiency of up to 95.8% and feeds it back into the AC grid, significantly reducing operating costs and thermal dissipation. Featuring an auto-ranging (constant power) output characteristic, it delivers 0-360 V and 0-480 A, achieving the full 60 kW rating across a wide operating range, making it a versatile and cost-effective solution compared to traditional fixed-range supplies.

This 6U high, 19-inch rack-mount unit is equipped with standard forced air cooling and the optional integrated water cooling system (WC version) for demanding applications. It accepts a wide three-phase AC input (380-480 V ±10%, 45-65 Hz) with active Power Factor Correction (typical 0.99). Built-in galvanically isolated interfaces include USB, Ethernet, and a DB15 analog port for control and monitoring. For system expansion, the integrated Master-Slave and Share-Bus allow seamless parallel operation of up to 64 units of different power ratings (same voltage class) to create systems up to 3840 kW.
