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 sources from 24 V DC network
• without UPS function
• fulfils requirements for SELV sources
