EA-PSB 10060-340 3U 10000W Programmable Bidirectional DC Power Supply

The EA-PSB 10060-340 3U is a high-performance programmable bidirectional DC power supply that integrates the functions of a laboratory power supply (source) and a regenerative electronic load (sink) into a single 3U 19" rack-mount unit. As a key model of the PSB 10000 3U series, this 60V device delivers a DC output range of 0-60V and a DC current range of 0-340A, achieving a total power of 10000W. When operating on a 208V AC supply, the device automatically derates to 6000W. It boasts an efficiency of up to 94.5%, significantly reducing energy loss, especially in sink mode where it recovers energy and feeds it back into the grid as an energy recuperating DC source. The device features seamless and gapless switching between source and sink modes at zero crossing, making it an ideal solution for applications requiring both a DC power source and a DC electronic load. The built-in function generator supports sine, triangle, rectangle, arbitrary, and dedicated PV/EN50530 solar panel and fuel cell simulation curves, with a user-defined arbitrary waveform generator of up to 99 points. Remote control is facilitated via standard built-in USB and Ethernet ports, a galvanically isolated analog interface (0-5V or 0-10V switchable), and an optional slot for plug-in interface modules (RS232, CAN, CANopen, Profibus, Profinet, EtherCAT, ModBus TCP). The device offers high precision with display accuracy of ≤0.05% for voltage and ≤0.1% for current, and features low ripple of ≤10 mV (rms) and ≤100 mV (pp). For scalability, up to 64 units can be connected in a master-slave parallel configuration to create high-power systems up to 640kW, with true totaling of actual values. Safety features include adjustable overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OT) protection.
