EA-PUB 11000-160 6U WC Programmable Bidirectional DC Power Unit

The EA-PUB 11000-160 6U WC is a high-performance, water-cooled, programmable bidirectional DC power supply unit capable of delivering up to 60 kW. It functions both as a precise power source (source) and a regenerative electronic load (sink), recovering up to 96.5% of energy back to the AC grid with high efficiency. Designed for demanding industrial and laboratory applications, it features a wide output range of 0-1000 V and 0-160 A with auto-ranging (constant power) characteristics. With three-phase AC input (380-480 V ±10%), active Power Factor Correction (PFC ~0.99), and comprehensive digital interfaces, it is ideal for battery testing, fuel cell test systems, PV inverter testing, on-board charger validation, and battery simulation/recycling.

Key Features
