AVR SPS-T10 is a solid state electronic device designed to develop and regulate voltage of an brush less alternator. It constantly monitors alternator voltage, frequency and field current to maintain constant voltage. SPS-T10 is designed to sense both Phase to phase and Phase to Neutral voltage, enabling to work for both three phase or single phase brush less alternators. These AVR is compatible with any type of brush less alternator if used within its specified output power limits. Uniquely a relay less circuit of AVR requires only 5 V AC to build up voltage. AVR SPS-T10 parameters can be adjusted precisely through 25 turns potentiometers. It has built in protections like Under frequency roll off ( UFRO) with LED indicator to protect winding burn out due to low frequency, stability setting to set load response time, over excitation current time delay trip with LED indicator and fuse protection.
