3-PM Voltage monitoring module

3-PM Voltage monitoring module

To avoid risks from mains failures, it is necessary to permanently monitor the function of the mains lighting light distributors in order to switch on the safety lighting in the event of a fault. Thus the CEAG 3-PM modules are an important part of the safety system. If one phase fails, the CEAG 3-PM module switches a relay contact and interrupts the 24 V current loop to the emergency lighting units. All emergency luminaires in stand-by circuit are switched to continuous light. A second relay contact is used to signal the power failure.
