REGULATOR GENERATOR AUTOMATIC FOR SX440 VOLTAGE AVR CF FLASH COMPACT OEM WHOLESALE MEMORY 256MB 20 X CARD LOT ML/MIN ROLLER F3 1330 MC6 6 DISPENSING PUMP TYPE PERISTALTIC VERTICAL 0.5-3L EVAPORATOR ROTARY RE3000B CONDENSER 20-200RPM 1PC FST1 IN KEYENCE NEW BOX FS-T1 Description: 1. SX440 is a two phase sensed Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator. 2. The AVR senses the voltage in the main generator winding and control the power fed to the exciter stator and hence the main rotor to maintain the generator output voltage within the specified limits, compensating for load spry, temperature and power factor of the generator. 3. Excitation power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of nonlinear loads and to reduce radio frequency interference on the generator terminals. Sustained generator short circuit current is another feature of the PMG system. 4. The AVR has the facility for droop CT connection, to allow parallel running with other similarly equipped generators. Specification. Sensing Input. Voltage: 190-264V ac max, 1 phase 2 wire.
