DC-DC Converter XPPower DTE40 Series 40 Watts Regulated single outputs from 24VDC to 48VDC xxx Series Wide 4:1 input range Fully encapsulated chassis mount Optional DIN rail version IEC/UL/cUL62368-1 safety approvals EN55032 class A with no external components Remote on/off 2.5kVDC isolation -40C to +95C operating temperature Full power to 80C Dimensions: MTBF 750kHrs (MIL-DHBK-27F, +25C GB) DTE40: 4.41 x 2.51 x 1.01 (112 x 63.8 x 25.6 mm) 3 year warranty Available in two wide (4:1) input ranges for nominal 24VDC and 48VDC, the DTE20 series of encapsulated 40W DC-DC converters are chassis mount as standard or can be ordered with a DIN rail mount. They have screw terminals for ease of connection and an LED provides clear power good indication. Remote On/Off is standard and when inhibited the standby current is just 3mA. Isolation is 2.5kVDC input/output providing excellent separation between supply and load. The modules are fully protected against input undervoltage, short circuit and overload conditions. These features, along with a rugged design and wide operating temperature range make the DTE20 series suitable for a variety of commercial and industrial applications.
