Power Distribution System SVS18 Description The power distribution system SVS18 optimises the DC 24 V distribution in automation and process control, in the production area of the chemical industry and in power plants. The power distribution system SVS18 DIN rail mounting distributes all voltage potentials supplied by a 24 V power supply (SMPS) onto 10 ways F1 to F10 (arranged from right to left). The system offers 2 integral redundancy diodes in each protected load output and selectively protects the connected loads such as controls, transformers, actuators, magnetic yoke subassemblies, bus modules etc. by means of the circuit breaker fitted. With a max. total current of 25 A and a typical load current of 3 A per way (max. 6 A in limited continuous duty) the SVS18 provides ease of distribution and sub-distribution in short-circuit-limited DC 24 V applications. All auxiliary contacts (make contacts) of the plugged-in circuit breakers are connected in series and allow group signalling in accordance with the closed-circuit principle. The 10 protected »L+« load outputs with 2 redundancy diodes per way significantly reduce the otherwise standard wiring time. All terminals of the DC 24 V supply, load outputs with 0 V return conductor as well as the signalling terminals are screwless spring-loaded terminals.
