EA-PSB 10200-140 3U Programmable Bidirectional DC Power Supply 10000W

The EA-PSB 10200-140 3U is a high-performance programmable bidirectional DC power supply from the PSB 10000 3U series, integrating a laboratory power supply and an electronic DC load into a single 19-inch 3U rack-mount unit. This versatile instrument functions as a DC power source and a regenerative DC load with an energy recovery system, feeding energy back into the grid with up to 94.5% efficiency to reduce waste and operating costs. It delivers a voltage range of 0-200V, current up to 140A, and power up to 10000W (6000W derated at 208V AC input). The device operates in constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR) modes, with seamless zero-crossing switching between source and sink. Ideal for applications such as battery charge and discharge testing, photovoltaic PV simulator, solar panel simulator, and automotive test systems. Featuring a 5" color TFT touch screen, integrated function generator (sine, triangle, rectangular, arbitrary, and more), and multiple interfaces including USB, Ethernet, and a galvanically isolated analog interface (0-5V/0-10V switchable), it offers precise control and monitoring. Ripple is ≤40mV rms / ≤300mV pp, output capacitance is 5040µF, and up to 64 units can be paralleled in master-slave operation for higher power requirements. Comprehensive protections include adjustable OVP, OCP, OPP, and overtemperature shutdown.
