EA Elektro-Automatik Autoranging Bench Power Supplies
The EA-BT 20000 Series Battery Testers can perform battery cell, module or pack tests up to 1.92MW and features active pre-charge to prevent unwanted inrush currents when the test object is connected. Voltages up to 2000V allow testing of current and next-gen battery pack architecture.
The EA-BT 20000 Triple model has 3 channels rated up to 600A per channel, which can be paralleled for up to 1800A from a single instrument. A power capacity up to 10kW per channel and 1 ms communication speed maximizes throughput.
How to select an EA-1Autoranging Gives Flexibility0000 Series model
EA Elektro-Automatik products have autoranging, which allows the supply or load to operate at max power across a range of voltages and currents, down to 33% of the rated output maximum.
Compare this to traditional power supplies, which can only output their rated power at their max voltage and max current. Applying the maximum voltage to a device under test (DUT) is rare, which means most of the time, that supply is not being used to its full potential.
How does it work? EA sources automatically offer more current at lower voltages (or more voltage at lower currents), allowing the supply to continue outputting the rated power. This allows a single source to address multiple voltage and current combinations that would otherwise require multiple supplies.
