DC-DC Converters

DTE40 Series

40W 4:1 DC-DC converter in a chassis mount as standard, or DIN rail mount as an option

Available in two wide (4:1) input ranges for nominal 24VDC & 48VDC, the DTE40 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 DTE40 series suitable for a variety of commercial and industrial electronics applications.
