The switching power supply units are designed for an input
voltage range of 85 to 300 V AC (0 to 400 Hz) or 150 to 380 V DC.
The device supplies 24 V DC on the output side.
The device offers the following features:
•
The output is potential-free in accordance with VDE 0551.
•
Can be used in the tropics - cast resin, fully encapsulated
•
Short circuit proof, overload and no load resistant
•
Protected against pole reversal on the output
•
The input can be protected with a 0.8A delayed fuse.
The green LED (see Fig. 1) signals that the device was connected
correctly on the input side and the supply voltage is available.
The red LED (see Fig. 1) signals a malfunction due to short circuit,
excess temperature or overload. After the correction of the
malfunction and a cooling off period, the power supply can be
put into operation again.
