280W, Dual-output, convection cooled, industrial
quality DC-DC converters offer wide selection of input voltages

The DCW 282-F1W Series is a recent addition to ABSOPULSE’s line of dual output, convection cooled dc-dc converters. The design uses high efficiency power conversion topology to deliver up to 280W output power. The unit has two fully independent regulated and isolated outputs, each providing any voltage between of 5V and 125Vdc.

The converters are available with either fixed or wide range inputs. The fixed input voltages include 36Vdc, 48Vdc, 125Vdc, or 250Vdc with wide input ranges. Models that accept wide input ranges of between 20-60Vdc or 65-160Vdc, are also available.

The series is suitable for a broad range of industrial applications. They are designed for compliance with EN/UL60950-1 and equivalent safety standards. Electronic protection includes 2250Vdc input-output isolation, inrush current limiting, reverse polarity, over voltage, over temperature and short circuit conditions. The input and output are filtered for low noise. The input meets EN55022 Class A with wide margins.

The series operates at full specification over a 0°C to +50°C operating temperature range without derating. Cooling is by conduction to customer heat sink or chassis and by natural convection. This series is housed in a rugged, compact, vented 163 x 51 x 200 mm enclosure.

For dual output power conversion with an 200 to 370Vdc input range, see the DCH 282-F1W. This 250W converter also measures 163 x 51 x 200 mm, F1W chassis.

ABSOPULSE offers an extensive range of DC-DC converters designed for operation in rugged industrial environments. Please contact us to discuss your requirements.
