EA-BT 20000 Series
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.
| POWER | VOLTAGE | CURRENT |
| Up to 30 kW | Up to 2000 V | Up to 1000 A |
