APR SERIESCLASS 200 EQUIPMENTAPR SERIESVOLTAGE REGULATORAPR 63-5/UL APR 125-5The APR series voltage regulators provide a small, reliable and economical voltage regulator for50 or 60 Hz brushless ac generators. The APR has frequency compensation which aids systemblock load pickup performance and controls excitation when operating below synchronousspeed. The regulator is designed for prime and standby power applications for small and mediumsized brushless generators. Accessory equipment can adapt the APR to a broad range ofspecialized applications.FEATURES:• Regulation Accuracy better than ±0.25%• Frequency Compensated• Overexcitation Shutdown• Solid State Voltage Buildup• Moisture Proof Potted assembly• Mechanically Rugged• Remote Voltage Adjust Rheostat Supplied• Small Size, Reliable, Low Cost• Built-in EMI Filter• Fast Response Time• Applicable to 50 or 60 Hz Systems• Complete Accessory Line available• CSA certified• UL recognizedADDITIONAL INFORMATIONINSTRUCTION MANUALRequest publication 9168700990 (APR63-5)Request publication 9168800990 (APR125-5)FEATURES andAPPLICATIONSthis pageDESCRIPTION andSPECIFICATIONSPage 2PERFORMANCECURVESPage 3DIMENSIONS andINTERCONNECTPage 4SWA-78-01P.

APR SERIESDESCRIPTIONThe APR series voltage regulators are completely solidstateand use an electromagnetic interference (EMI) suppressioncircuit to reduce EMI generated by the regulator.Voltage is internally or remotely adjustable. The APR hasa jumper selectable, frequency compensated operatingcharacteristic as shown by Figures 1 and 2.SPECIFICATIONSOUTPUT POWER:Voltage Output Output Forcing ForcingRegulator Voltage Current Voltage CurrentAPR 63.5 Vdc 5.0 Adc 100 Vdc 8.0 Adc63-5/ULAPR 125 Vdc 5.0 Adc 200 Vdc 8.0 Adc125-5EXCITER FIELD DC RESISTANCE:Voltage Regulator Minimum MaximumAPR 63-5/UL 12.6 ohms 100 ohmsAPR 125-5 25 ohms 100 ohmsPOWER DISSIPATED:APR 63-5/ULAPR 125-5AC INPUT POWER:9 Watts (max.)25 Watts (max.)Voltage BurdenAPR 63-5/UL 190 to 277 Vac, single 650 VA (max.)phase, 50/60 Hz. ±10%APR 125-5 190 to 277 Vac, single 1000 VA (max.)phase, 50/60 Hz. ±10%During start-up, the solid-state voltage build-up circuitoperates from generator output residual voltages aslow as 6Vac.
