Datasheet

DTE40 series 

## 40W 

## **DC-DC power supplies** 

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 (suffix -D). 

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. 

## **Features** 

- f Regulated single output 

- f 4:1 input range

Notes: 

1. Input current measured at nominal input voltage. 

2. Typical values. 

   4.  Input current is typically 3mA at nominal input voltage when output is remotely turned off. 

3. For optional version fitted with DIN Clip add suffix ‘-D’ e.g. DTE4024S24-D.
