Power supply source for TC700 from 230 VAC network including UPS circuits

Power supply sources are designed for feeding the TECOMAT TC700 PLCs. They are pulse-controlled, part of which is the circuit for monitoring of network voltage failure and signalisation of power source load. Power supply sources can be arranged in parallel (i.e. they can be fitted in the same rack or in different racks mutually interconnected with power supply) with the possibility of source output increase (the sum of outputs of particular sources) or for achieving of the redundant supply of the system. The power supply sources can be fitted at any position of any rack of the assembly. All sources fulfil the requirements for the sources with safe voltage (SELV).

• power supply source from 230 VAC network
• equipped with UPS circuit, which allows after connection of external accumulators (2 x 12V/0,8 to 8 Ah) automatic backup of operation during power supply source supply failure
• fulfils requirements for SELV sources
