EXACT GENERIC REPLACEMENT MX321 - Is a two phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brush-less generator. 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. SENSING INPUT Voltage: 190 - 264V ac max, 2 or 3 phase Frequency: 50 - 60 HZ nominal POWER INPUT (PMG) Voltage: 170-220V ac max, 3 phase, 3 wire Current: 3A/phase Frequency: 100 - 120 Hz nominal OUTPUT Voltage: max 120V dc Current: continuous 3.7 A Intermittent 6A for 10 secs. Resistance: 15 ohms minimum REGULATION +/- 0.5% RMS with 4% engine governing THERMAL DRIFT 0.02% per deg. C chance in AVR ambient SOFT START RAMP TIME 0.4 - 4 seconds TYPICAL SYSTEM RESPONSE AVR response 10 ms Field current to 90% 80 ms Machine Volts to 97% 300 ms
