automatic battery charger / lithium-ion / portable / for railway applications

Absopulse?s BCH 1K5T-400 battery charger uses high-frequency conversion technology to deliver up to 1500W continuous output power. It was designed to charge a 400V lithium-ion battery; other battery configurations are also available. It has an automatic two step charge mode: it runs at full 4A charging current until the pre-set voltage threshold of 380V is reached, then switches to a lower 1A maintenance current.

An analog voltmeter and ammeter located on the front-panel 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 either 115Vac or 230Vac, factory set. Power factor correction is available on request.

The BCH 1K5T-400 is conformal coated, heavily ruggedized and is housed in a water-proof Pelican case with a sturdy handle for portability and easy use in the field. The case measures
502 x 401 x 190 mm and the entire unit weighs approximately 12 kilograms.

Cooling by built-in fans which allows for operation in the 0?C to 50?C temperature range. Extended temperature ranges are available on request. Protection includes inrush current limiting, over-voltage protection, short circuit protection, a self-resetting thermostat for thermal protection. The output is protected against reverse battery connection by built-in crossbar diode and output breaker.

Absopulse Electronics designs and manufactures an extensive range of rugged, portable battery chargers to customer specifications.
