Power distribution system SVS14 Description The power distribution system SVS14-10 optimises DC 24 V distribution on the field level in automated process control, industrial production and chemical plants. The system holds an integral ammeter (display 25 A) for the total current and offers ten ways for electronic and thermal-magnetic circuit breakers including group signalling. It allows protection of transformers, actuators, solenoids, peripheral PLCs, intelligent terminals etc. on the field level. Particularly for systems with a great number of sensors/actuators the SVS14 power distribution system enables a space-saving and cost-effective design of protection control cabinets. Any load circuit which might be disconnected due to overload or short circuit generates a single signal which will be summarised in a group signal directly on the power distribution system and which will be fed back directly to control. The SVS14 is a track-mountable system and accommodates 10 electronic or thermal-magnetic circuit breakers. All terminals (entry line DC +24 V, GND (-) for self-supply, load outputs L(+) and group signalling are standard screw terminals. Technical data (Tamb = 25 °C, UB = DC 24 V) Application The SVS14 accommodates the following E-T-A types: Electronic circuit breaker ESS20-003.. Electronic circuit protector ESX10-103.. Thermal-magnetic circuit breaker 2210-S211, 3600-P10, 3900-P10 Systematic integration of power distribution, protection and signalling functions Power distribution and selective protection of DC 24 V loads from a single source Group signalling pre-wired Integral Si contact (per way) for free slots, Si circuit can be closed.
