TND/svc raupapa tino ngaohiko ngaohiko regulator consist of contact auto transformer, servo motor, automatic control circuit etcWhen grid ngaohiko instability or load change , aunoa sampling control circuit sends a signal to drive servo motor, adjust theposition of the self coupling voltage regulator for carbon brush, make the output voltage rating reach the stable state.This product has the waveform distortionless, faithful performance distortionless. te mahi mo te wa roa me etahi atu ahuatanga, he wa roa, mo te ngaohiko, he mahi tiaki i raro i te ngaohiko. Ka taea te whakamahi whanui i roto i te hiko e hiahia ana kia mau tonu te ngaohiko, he ahua pai te tuku hiko. Me mohio kei te mahi noa o taputapu hiko
