Loop Monitored 4 Amp External Power Supply
The Ext. power supply 3366 consists of a rectifier (the main power source) and a charger board mounted in a grey metal housing, which also has space for two maintenance-free sealed Lead-Acid backup batteries, rated 12 V, 6.5-7.5 Ah (the second power source). Larger batteries (up to 60 Ah) have to be placed outside the housing.
The unit is connected to a COM loop. It is monitored from the c.i.e. and e.g. loss of the main power source (230 V AC) will generate a fault in the c.i.e. There are cable inlets on the top, bottom and back sides of the housing and two compression glands are attached.
