Compact, Bidirectional DC Power Supplies, up to 3.84MW
Compact, Bidirectional DC Power Supplies, up to 3.84MW
The EA PSB 20000 and 10000 Series bidirectional DC power supplies combine high efficiency, precision, and versatility. Regenerative operation returns energy to the grid at over 96% efficiency, reducing heat and noise. True autoranging maximizes power across wide voltage and current ranges, while control interfaces enable seamless integration. The 20000 Series adds three channels, 1 ms response, safety sense, a function generator, and preloaded routines for battery, fuel cell, and PV simulation.

Bidirectional Supplies Offer Full Solutions from a Single Instrument
The EA PSB 20000 Series delivers three independent, fully isolated channels for parallel testing of motors, inverters, and onboard chargers—accelerating development and validation. Safety sense ensures accurate voltage at the device under test (DUT), protecting sensitive equipment, while each channel provides up to 10 kW, 0–920V, and 340A, with 1ms communication for fast, precise, and reliable operation.
EA Elektro-Automatik bidirectional DC supplies can both source and sink power (Quadrants I & II), making them ideal for testing batteries, solar inverters, and automotive powertrains. For full four-quadrant operation across positive and negative voltages and currents, Keithley Source Measure Units are recommended.
EA Elektro-Automatik products feature autoranging, enabling the supply or load to deliver full rated power across a wide range of voltages and currents—even down to 33% of maximum output. Unlike traditional power supplies, which reach full power only at their maximum voltage and current, EA autoranging sources automatically adjust, providing more current at lower voltages or more voltage at lower currents. This ensures efficient use of the supply and allows a single unit to cover multiple voltage and current combinations that would otherwise require several devices.
EA regenerative loads and bidirectional supplies capture sunk energy and feed it back to the facility or public grid, reducing waste, cutting cooling requirements, and improving test efficiency.
