More details

New AVR VR6 K65-12B Caterpillar Automatic Voltage Regulator    Model K65-12B Output power (with a 240Vac Input): 12 Adc @ 65 Vdc maximum continuous. 25 Adc @ 125 Vdc forcing for 10 seconds. AC input power: 100 to 280 Vac, single-phase 50 to 400 Hz, or 63 to 105 Vac; three phase,50 to 400 Hz, 1092 VA maximum continuous burden AC sensing voltage: 90 to 140 Vac, 50/60 Hz; single- or three-phase. External voltage adjust rheostat: 10k ohm, 2 W, potentiometer Regulation accuracy: ±0.5% Average responding Voltage drift: ±1% voltage variation for a 40° C(104° F) change. Response time: < 4 milliseconds Frequency compensation: 1 or 2 V/Hz jumper selectable with knee adjustable from 45 Hz to 65Hz. EMI suppression: Internal filter Voltage Build-Up: Internal provisions for automatic voltage build-up from generator residual voltages as low as six Vac. Over excitation shutdown: Over excitation protection starts timing at 90 Vdc ±5% and takes the output to zero in greater than 30 seconds. The output can be 125Vdc for greater than 10 seconds. Droop 1 Aor 5 A, <10 VA, adjustable from 0 to 10% at rated input current, 0.8 power factor UL recognized/CSA certified UL Recognized per Standard 508,UL File NO. E97035. CSA certified per Standard CAN/CSA-C22.2 No.14-95, CSA File No. LR 23131
