Absopulse 1000W Rugged, Compact DC-DC Converter Suits Harsh Industrial Environments

Absopulse announced the BAP 65-125-XXFT Series of rugged, industrial quality dc-dc converters which deliver up to 1000W continuous output power from a compact chassis with a 155 x 64 x 300mm total footprint. The units deliver 24V/40A or 48Vdc/20A and accept input voltages of 110 or 125Vdc. Other input/output values are also possible. An optional built-in redundancy diode allows for parallel and N+1 operation. An output fail alarm is also available as an option.

Cooled by long life built-in fans and by conduction, the units are rated for full specification at a 0 to 50°C temperature range; extended temperature ranges are also possible with de-rating. The calculated MTBF of the units is 130,000 hours at 45°C, with demonstrated figures expected to be significantly higher.

These rugged converters meet EN61373/IEC61373 shock and vibration standards. The units are filtered to meet EN 55022 Class A EMI. Output ripple/noise is less than 1% peak-to-peak and combined line/load regulation of less than ±1% from zero-load to full load. Protection includes inrush current limiting, reverse polarity protection and continuous current limiting with short-circuit protection with no hiccup. Efficiency is typically 85% at full load.

Standard versions of the BAP 65-125-XXFT series are priced in the US$386 range in quantities of 100.
