EA-PSB 10200-210 3U Programmable Bidirectional DC Power Supply 15000W

The EA-PSB 10200-210 3U is a high-power 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 source and sink with an energy recuperating system, feeding energy back into the grid with up to 94.5% efficiency to reduce waste and lower operating costs. It delivers a voltage range of 0-200V, current up to 210A, and power up to 15000W (9000W 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 test power supply, battery charger, solar panel simulator, photovoltaic simulator, fuel cell simulator, and power supply for photovoltaics testing. 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 7560µF, and up to 64 units can be paralleled in master-slave parallel operation for higher power requirements. Comprehensive protections include adjustable OVP, OCP, OPP, and overtemperature shutdown.

Key Features

• True Bidirectional Operation with Energy Recovery: Combines a programmable DC power supply and a DC electronic load in one unit with seamless switching; regenerates up to 94.5% of absorbed DC energy back to the AC grid, minimizing heat dissipation and lowering operating costs as an energy recuperating power supply.
• High Power Density & Versatile Output: Delivers 0-200V, 0-210A, and 0-15000W (9000W derated at 208V AC) in a compact 3U 19-inch rack-mount chassis; ideal for space-constrained industrial and test system power supply applications requiring high power and bidirectional capability.
• Integrated Advanced Function Generator: Built-in generator supports sine, triangular, rectangular, trapezoidal, arbitrary, DIN 40839, PV, fuel cell, battery test, and MPPT tracking curves, perfect for simulating solar panels, fuel cells, batteries, and complex load profiles.
