The WQ measures power or reactive power using a moving coil movement and a built-in electronic watt or var transducer.

Measuring power in a single-phase or three-phase network, the transducer PCB converts the signal into a DC current which is then fed to the moving coil instrument.

The DEIF WQ comes with a high degree of transient protection and is available in Q96 mm and Q144 mm sizes.
