INTRODUCTION

The VR63-4A/UL voltage regulator is designed for use on

50/60 Hz brushless generators. Regulator features include

frequency compensation, overexcitation shutdown, a solid-

state buildup circuit, and EMI filtering.

FUNCTIONAL DESCRIPTION

Frequency Compensation

The frequency compensation characteristic of Figure 1 is

used to improve system load pickup performance by

restraining voltage recovery until frequency has also

started to recover.

The regulator is shipped from the factory set at a 45-Hz

corner frequency for 50 Hz systems. For 60 Hz systems, a

55-Hz corner frequency is achieved by removing the

jumper from the HZ terminals.

Overexcitation Shutdown

If the exciter field voltage exceeds 100 Vdc ±5 Vdc, the

regulator automatically removes the field current after a

time delay. The time delay is inversely proportional to the

magnitude of the detected overvoltage condition up to the

135 ±5 Vdc point. Beyond 135 Vdc ±5 Vdc, the field

voltage is removed within 0.2 seconds. See Figure 2.

After shutdown, reset the regulator by decreasing the

voltage below 6 Vac either by stopping the prime mover or

by interrupting the regulator input with a reset switch for 2

seconds minimum.

INSTALLATION

Mounting

The regulator may be mounted on the generator in any

convenient position (optimum cooling occurs with the long

side of the regulator vertical). Refer to the drilling diagram

of Figure 3.

Exciter Field Power Circuit

Connect regulator terminal F+ to the brushless exciter field

terminal F+, and terminal F– to terminal F–.

CAUTION

The dc resistance of the exciter field must be

greater than or equal to 15 Ω and less than

100 Ω.

Power/Sensing Input Circuit

Connect as shown in Figures 4 and 5. Power for the

exciter field and regulator circuitry is derived from the

generator output or auxiliary winding. The operable power

input range is 190 to 240 Vac.
