The power of three

EA-BT 20000 Series

Optimized for battery testing and battery simulation, the EA-BT 20000 Series are fully bidirectional supplies, allowing full control for both discharging and charging battery cells, packs, or modules. A max power of 30kW and the ability to parallel channels for up to 1800 A allows you to scale a solution to meet your needs. Included regenerative technology recovers energy during battery discharge or while simulating a charging battery and feeds that energy back into the local grid that would otherwise be lost as heat, reducing operating expenses and HVAC costs.

3 Channels – multiply your throughput: The EA-BT 20000 Triple battery tester brings three 10kW channels to a single 4U instrument. Each channel can be controlled individually to maximize test throughput, or paralleled together for higher current when test needs require.

Up to 30 kWUp to 2000 VUp to 1000 A
