Three Phase Calibration Source - P 301

Three Phase Energy Meter Calibration Instrument

EDUCE TECH INSTRUMENTS has introduced Keyboard version of Three Phase Power Source (P 301). The instrument generates independent Voltage, Current,Frequency and Power factor.
The Parameters are entered through the keyboard provided.
Large LCD Display is provided for the logging & Measurement.
The data can also be Entered and read from the PC via RS 232 port.
Built-In Timer is provided with display.
The system operates on 230VAC Single Phase Power supply.

The System uses digitally synthesized sinusoidal waves with analog amplification for the lower Total Harmonic Distortion (THD) and for the higher accuracy. The Output waveform has 60dB fundamental frequency above the noise floor on the full-scale reading and the stability of better than 0.2%.
The Instrument is designed for Calibration of Digital Panel Meters like Energy Meter, Watt-Hour Meter, Voltmeter, Ammeter, P.F Meter etc.
