template AVR MX321 Automatic Voltage Regulator for Stamford Brushless Generator Brief introduction: 3 Phase Sensing Permanent Magnet Generator type voltage regulator is a compatible replacement for Newage Stamford MX321 and Onan 305-0823. MX321 is a three phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. Excitation power is derived from a three phased 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. The AVR sense the voltage in the main generator winding and controls the excitation to maintain the generator output voltage with the specified limits, compensating for load, speed, temperature and power factor of the generator. Three phase RMS sensing is employed for superior voltage regulation. Adjustable soft start circuitry is included to provide a smooth controlled build up of generator output voltage. Specification : Voltage Regulation < ±0.5% RMS For Use In Parallel Operation RAMP, DIP, DWELL, DROOP, RMS, U/F, Over Voltage & Over Excitation Adjustment Functions Over Exc. / Over Volt. & UFRO LED Indicators Current Limiting Function Sensing Input Voltage : 190-264V ac max, 2 or 3 phase Frequency : 50-60HZ nominal POWER INPUT Voltage : 170-220 V ac max, 3 phase,3 wire CURRENT: 3A/phase Frequency : 100-120HZ nominal Output Voltage : max 120V dc Current : continuous 3.7A dc Intermittent 6A for 10 secs Resistance : 15 ohms minimum REGULATION: +/-0.5% RMS with 4% engine governing THERMAL DRIFT: 0.02% per deg.C change in AVR ambient TYPICAL SYSTEM RESPONSE: AVR Respones : 10ms Filed current to 90% 80ms Machine Volts to 97% 300ms EXTERNAL VOLTAGE ADJUSTMENT: +/-10% with 5k ohm 1 watt trimmer UNDER FREQUENCY PROTECTION: Set point 95%HZ Slope: 100% -300% down to 30HZ Max dwell: 20% volts/S recovery UNIT POWER DISSIPATION: 18 watts maximum ANALOGUE INPUT: Maximum input +/-5V dc Sensitivity 1V for 5% Generator Volts(adjustable) Input resistance 1k ohm QUADRATURE DROOP INPUT: 10 ohms burden Max. sensitivity: 0.22A for 5% droop OPF Max. input:0.33A CURRENT LIMIT INPUT: 10 ohms burden Sensitivity range: 0.5-1A OVER VOLTAGE DETECTOR INPUT: Set point:300V, time delay:1 sec CB trip coil volts:10-30 vdc CB trip coil RESISTANCE: 20-60 ohms OVER EXCITATION PROTECTION: Set point:75vdc Time relay:8-15 sec Environmental: Vibration: 20-100HZ : 50mm/sec 100Hz 2kHz : 3.3g +70 C Relative Humidity 0-70C : 95% 1.Your valid phone number is very necessary for the shipping, otherwise we can't guarantee that the package would safely arrives. 2.
