Power Distribution System SVS04
Description
The SVS04 power distribution system for symmetrical DIN rail
mounting is designed to distribute power from a switch-mode power
supply to 4 or 8 channels. Selective protection of the load output
circuits is provided by the plug-in type circuit breakers installed. With
a max. load current of 8A per channel and a max. total current of
40A the SVS04 provides ease of wiring in short circuit current limited
DC24V applications. Five protected “L+” load outputs per way and
15 or 30 minus terminals significantly reduce wiring time enormously.
Electronic circuit breaker ESS20-003, electronic circuit protector
ESX10-103 and thermal-magnetic circuit breakers 2210-S21 are all
suitable for use with the SVS04, plugging directly into the sockets
provided for each of the 4 or 8 outputs.
