ADVR-073

Hybrid Universal Analog Digital Voltage Regulator 7Amp

ADVR-073 is an Hybrid Analog/Digital Voltage Regulator. It’s desigined with CPU inside which eliminates voltage drifting that caused by temperature variation. This designed has greatly improves the reliability of AVR. ADVR-073 has over excitation and loss of sensing shutdown protections which will prevent AVR from damaging in overload situation.
