Modular monitoring relay PH001 & PAN45-01-00

under-voltageover-voltagephase sequence

The PH001 coupled with the PAN45-01-00 is the most complete set to monitor your single-phase or three-phase electrical installation, with or without neutral. The PAN45-01-00 is intended to display the information and states detected by the PH001 on the front of the cabinet in complete safety. The PAN45-01-00 is supplied with very low voltage 5Vdc by isolated 1kV converter and 3kV optocouplers located in the PH001 box. It protects you against: – reverse phase rotation. – overvoltages and under voltages. – the voltage differences between phases due to loss of neutral or asymmetry. (Over / under voltage protection usable in single-phase) It continuously monitors: – the presence of the 3 phases and the direction of rotation. – the under voltage and overvoltage of each of the phases. – the asymmetry of each phase and loss of neutral. Equipped with a positive safety relay with 1RT contact, it ensures : – an adjustable delayed shutdown when exceeding the setting. – an instantaneous shutdown in the event of an abnormally high overshoot. Supply: the box is self-powered by the inputs to be controlled
