DC-DC Converters

DTJ20 Series

Lower cost chassis & DIN rail mount 20W 4:1 input DC-DC converters

Housed in a chassis mount or optional DIN rail mount package, with screw terminals for ease of connection, the DTJ20 take a nominal 12/24 or 24/48VDC input and convert to a fixed single voltage between 3.3 & 15VDC or dual voltage between ±5.0 and ±15VDC, an LED indicator provides clear ‘power good’ indication.

The 20W chassis mount and DIN rail mount DC-DC converters allows for easy and convenient integration into a variety of industrial and commercial applications. Typical uses are: Communication systems; Door control; Elevator/travellator/escalator control; Fun fair/amusement/gaming systems; Process monitoring & control; Robotics; Surveillance & detection; System & safety monitoring; Telemetry & many other applications.
