Product Overview

The 256-TWMU-QQHG-C6-SS is a Power Transducer with 3 phase 3 wire unbalanced load. These transducers utilise the well proven 'time division multiplication' method of measuring instantaneous power over a wide range of input waveforms. In the self powered version the system voltage provides both power supply and an input to the voltage modulation circuit of an oscillator. Square wave pulses from a multi-vibrator circuit with a mark-space ratio varied by the measured voltage and amplitude varied by the measured current, are fed to an integrator and an output amplifier circuit. The D.C. milliamp signal produced is therefore directly proportional to the power input. All inputs are isolated by the use of transformers. For large voltage variations use the auxiliary powered versions. Self powered units permit voltage variations up to +20% of the nominal input. Measures both import and export power.
