DATAKOM AVR-10-D is a microprocessor controlled digital voltage regulator designed for synchronous brushless alternators. It features high static and dynamic voltage stability in a compact and low-cost package. The device has open chassis, resin molded design and is intended to be mounted inside the alternator’s terminal box. The output stage of the device is a Half Wave thyristor output associated with a freewheeling diode. The unit does not include moving parts; therefore, it is able to operate in highly vibrating environments. The unit regulates the alternator voltage by adjusting the DC voltage applied to the excitation winding. It uses digital PID algorithms for the maximum precision and the best dynamic response. FEATURES Supports both AREP-PMG-SHUNT operations 10 Amps continuous current output capability 20 Amps forcing for 10 seconds Requires only 3VAC for build-up Microprocessor controlled 3 phase network connection Phase-phase or phase-neutral voltage control Selectable voltage regulation modes Single phase or 3 phase operation capability Compatible with 50 and 60Hz alternators Wide voltage range (42-277VAC Ph-N) 1 phase alternator load current connection Automatic reactive load sharing capability Automatic droop capability (positive or negative) Automatic alternator power limiting Analog load sharing inputs (±3V and 0-10V) LAM for low frequency protection, knee function Soft recovery from severe overloads Exciter over current protection High Temperature protection Sensing loss protection Programmable parameters All parameters programmable on the unit Optional non-isolated USB port Optional isolated RS-485 port Optional isolated CANBUS port Wide supply voltage range, 35-305VAC Wide voltage regulation range, 42-277VAC Resin molded design against vibration
