Caterpillar Generator AVR VR6 K65-12B K125-10B AUTOMATIC VOLTAGE REGULATOR VR6 WHERE THE WORLD TURNS FOR POWER

Reactive droop input: 1A or 5A. At maximum rated current droop is adjustable up to 10%. Maximum droop is proportional to current. Proper droop current transformer sizing is essential to correct operation of this feature. Series boost Able to sustain the generator output at 300% rated current for a minimum of ten seconds. Not required for PM.

If you have a droop CT option, cut off existing terminals from the droop CT harness wires. Install 125-9997 Fork Terminals (2) on both wires, and land the wires on the VR6 terminals "5" and "6". Note: VR6 Terminal "5" is used for 1 Amp CT which was utilized on R448 regulators.

This manual covers the VR6 voltage regulator which is used on 4/6 and 10/12 lead self-excited generators and permanent magnet generators. The VR6 regulator is typically located in the generator terminal box.

1 or 2 V/Hz jumper selectable with knee adjustable from 45 Hz to 65 Hz. Overexcitation protection starts timing at 90 Vdc ±5% and takes the output to zero in greater than 30 seconds. The output can be 125 Vdc for greater than 10 seconds. Overexcitation protection starts timing at 180 Vdc ±5% and takes the output to zero in greater than 30 seconds.

Reactive droop input: 1A or 5A. At maximum rated current droop is adjustable up to 10%. Maximum droop is proportional to current. Proper droop current transformer sizing is essential to correct operation of this feature. Able to sustain the generator output at 300% rated current for a minimum of ten seconds. Not required for PM.

At maximum rated current droop is adjustable up to 10%. Maximum droop is proportional to current. Proper droop current transformer sizing is essential to correct operation of this feature. Exciter field resistance: 3 to 10Ω

Sep 5, 2012 · VR6 has droop pot directly on regulator (first one from the top). Should be able to adjust droop up to 10%. -Existing droop CT can be used. VR6 terminal 5 is for 1A CT, terminal 5A is for 5A CT. Terminal 6 is common. Check CT secondary current with full load applied (will be less than 5A or 1A nominal rating), and verify correct connections.

Apr 8, 2008 · The CAT VR6 is the direct replacement, it is a nominal 63 volt 12 amp regulator. The CAT VR6 is only available in 240 sensing. The Basler AVC 63-12 is nearly indentical to the VR6, and available in three sensing ranges, 120, 240 and 480.
