An Absopulse Electronics product story
Edited by the Engineeringtalk editorial team Oct 27, 2009

Absopulse Electronics' BCH 1K5T-400 is a portable battery charger that uses high-frequency conversion technology to deliver up to 1500W continuous output power.

The charger was designed to charge a 400V lithium-ion battery and other battery configurations are also available.

It has an automatic two-step charge mode, running at full 4A charging current until the preset voltage threshold of 380V is reached, then switching to a lower 1A maintenance current.

An analogue voltmeter and an ammeter, located on the upper surface of the unit, indicate charge current and battery voltage status.

Different thresholds for 4A/1A switchover point and open-circuit voltage are available on request.

A built-in output separation diode prevents battery discharge back into the charger if the AC is disconnected.

The input accepts 115 or 230V AC, factory set and power-factor correction is available on request.

The BCH 1K5T-400 is conformal coated, heavily ruggedised and housed in a waterproof Pelican case with a sturdy handle for portability.

The case measures 502 x 401 x 190mm and the entire unit weighs approximately 12kg.

Cooling is by built-in fans which allows for operation in the 0 to 50C temperature range.

Extended temperature ranges are available.

Protection includes inrush current limiting, over-voltage protection, short-circuit protection and a self-resetting thermostat for thermal protection.

The output is protected against reverse battery connection by built-in crossbar diode and output breaker.
