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.
Features:
Voltage regulation < +/- 0.5%
220/380/440/480 Vac programmable input
Rugged compact design
With under frequency protection
Over excitation protection
Soft start voltage ramping
EMI suppression
Built-in high capacity 8 Amp fuse
