The EA-BT 20000 Triple battery tester brings 3 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.

High precision and high speed

Every EA-BT 20000 Series includes external sense to measure voltage directly at the battery. This gives you greater precision in your measurements and reduces errors caused by voltage drop through test leads, most important when using high current.

Three channel models and 1 ms communication speed accelerate your testing on the bench and in automated systems. Active pre-charge, cable and connection checks, and cable overload protections further speed your testing and prevents downtime.

Auto ranging Gives Flexibility

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.

Regeneration turns waste into savings

EA regenerative electronic loads and bidirectional supplies can recover up to 96% of the energy they sink, that means the AC mains connection is also used as output for the back-feed of the supplied DC energy.

Traditional electronic loads or resistor banks dissipate their sunk power by turning it into heat. This can require large cooling/HVAC solutions and that sunk energy is then lost forever as waste, reducing test and facility efficiency.

Energy recovered by EA loads is fed back into the local facility grid with a mains-synchronized inverter, where that energy can be used by other devices in the facility. If more energy is recovered than used by the facility (a possibility when testing fuel cell output, for example), the energy can be fed back out to the public grid.
