DC-DC Converters

DDC15 Series

15W 4:1 DC-DC converter in a low-profile DIN rail mount housing

The DDC15 series is a range DC-DC converters housed in a low-profile DIN rail case of a similar profile to that of circuit breakers, allowing them to fit in consumer unit style housings, or in standard control panel installations.

Designed to offer additional voltages in DIN rail power systems, provide isolated outputs & noise immunity or support battery powered or battery backed applications.

With a 4:1 wide input range the DDC15 series converters can be supplied by both a 12V or 24V nominal input and offer output voltages between 3.3VDC and 24VDC.

Typical applications are: Machine control; Process control; Factory automation; Building heating/aircon monitoring, control & security systems; Escalator/travelator/elevator/lift control.
