Functions of the power supply inputs of the 3KC3 transfer switching equipment
Inputs 101/102 and 201/202
The 3KC3 transfer switching equipment comes with two independent power supply inputs, 101/102 and 201/202.
-
A power supply must be applied at inputs 101/102 in order to be able to switch the transfer switching equipment in the direction of position I (II → 0 and 0 → I).
-
A power supply must be applied at inputs 201/202 in order to be able to switch the transfer switching equipment in the direction of position II (I → 0 and 0 → II).
Use of the dual power system (DPS) accessory offers complete reliability, as it makes it possible to switch to all three positions when either source I or source II is available. Alternatively, an external uninterrupted voltage supply can be connected to the network.
