An error signal is developedand used to control the dc field power inorder to maintain a constant generator out-put.Each regulator includes frequency compen-sation with selectable slope, inverse-timeoverexcitation shutdown, buildup circuitry,single- or three-phase voltage sensing, sin-gle- or three-phase shunt or permanentmagnet generator (PMG) power input, paral-lel droop compensation, and an accessoryinput. The accessory input provides com-patibility with devices such as var/powerfactor controllers or excitation limiters.SPECIFICATIONSPower Input ∗Configuration: 1-phase or 3-phaseFrequency: 50 to 400 HzVoltage RangeAVC63-12: 90 TO 153 VacAVC125-10: 180 to 264 VacMaximum Continuous BurdenAVC63-12: 1,092 VAAVC125-10: 1,750 VA∗ SeeOptions for Inrush Current ReductionModule information.Sensing InputConfiguration: 1-phase or 3-phaseBurden: <1 VA per phaseVoltage RangeOption A: 90 to 139 VacOption B: 180 to 264 VacNominal FrequencyOption 1: 50 or 60 HzOption 2: 400 Hz(See Table 4 for style/option information.)Accessory InputVoltage Range: ±3 VdcPower OutputMaximum Continuous OutputAVC63-12: 12 Adc at 63 VdcAVC125-10: 10 Adc at 125 Vdc10 Second Forcing OutputAVC63-12: 24 Adc at 125 VdcAVC125-10: 20 Adc at 250 VdcMinimum Field ResistanceAVC63-12: 5.25 ΩAVC125-10: 12.5 ΩRegulation Accuracy±0.5% of voltage setpoint, average responseVoltage Drift±0.5% variation for a 40°C (104°F) changeResponse Time<4 msFrequency CompensationOne or two jumper-selectable V/Hz curveswith knee frequency adjustable from 45 to65 Hz (50/60 Hz units) or 300 to 430 Hz(400 Hz units).

Humidity: 95%, non-condensingWeight: approx. 1.1 kg (2.5 lb)INSTALLATIONRegulators are contained in an encapsu-lated plastic case and may be mounted inany convenient position. A regulator may bemounted directly on a genset using UNF ¼-20 or equivalent hardware. Hardware selec-tion should be based on any expected ship-ping/transportation and operating conditions.The torque applied to the mounting hard-ware should not exceed 65 in-lb (7.34 N•m).See Figure 5 for regulator dimensions.CONNECTIONSBefore connecting the voltage regulator intoyour system, review the terminal descrip-tions listed in Table 1 and the connectiondiagrams in Figures 6 through 8.Table 1.
