The PQM II is an ideal option when continuous monitoring of a three-phase system is required. It provides measurement of current, voltage, real and reactive power, energy use, energy cost, power factor and frequency. The programmable set points and the 4 assignable output relays allow you to add control functions for specific applications. This includes a basic over / under current or voltage alarm, imbalance, load reduction based on demand and correction control of the capacitor power factor. More complex control is possible using the 4 switch inputs that can also be used for states such as open / closed switch, flow information, etc.
