Power Transducer Series

MULTI POWER MONITOR

(4 digital displays)

Functions & Features

• Measures simultaneously several variables of a heavy-

current power system: current, voltage, active, reactive and

apparent power, active and reactive energy, power factor,

frequency, etc.

• All measured values, counter values, display mode,

setting data are stored in the non-volatile memory at the

power off

• Conversion factors, system configuration, interval times

are programmable using the front buttons

• Open collector output for alarm or energy count

Typical Applications

• Multi-functional power monitor incorporated in an electric

device: saves space, wiring works, and cost
