GDVA-405 Multifunctional CE Confirmed IEC60044 Transformer Calibrator CT PT Analyzer





GDVA-405 CT PT Analyzer is a comprehensive CT and PT analyzer. It’s constant voltage and current is highly stable. DSP system controls the constant voltage and current source output and amplitude. This source generates AC of 0-125V and or DC of 0-0.5A current to sample CT. The DSP system besides controlling the sources, also samples data and communicates with the internal computer. Display screen is large LCD with touch pad.

GDVA-405 CT PT Analyzer is highly accurate with high noise immunity and is very user friendly.
