EA-PUB 10750-240 6U WC Programmable Bidirectional DC Power Supply with Water Cooling

The EA-PUB 10750-240 6U WC is a high-performance, programmable bidirectional DC power unit with integrated water cooling, capable of delivering up to 60 kW of power. It operates as both a DC power supply (source) and a regenerative electronic load (sink), with energy recovery efficiency up to 96.5%. With an autoranging output stage, it provides a wide voltage range of 0–750 V and current range of 0–240 A, maintaining full power across the entire operating envelope. The unit accepts a three-phase AC input of 380–480 V ±10% with active PFC (typical 0.99 power factor), making it suitable for global grid connections. It features precise regulation modes (CV, CC, CP, CR), fast transient response (CV rise/fall time ≤10 ms), and excellent stability (CV load regulation ≤0.05% FS). Designed for high-power testing applications, it supports parallel operation of up to 64 units via Master-Slave and Share-Bus interfaces, enabling systems up to 3840 kW.
