Regulation is provided by sensing the generator output voltage, converting it to a dc signal
and comparing the signal to a reference voltage signal. An error signal is developed and
used to control the dc field power in order to
maintain a constant generator output.

The Basler APR 63-5 Voltage Regulator is a
CSA/UL approved unit contained in an encapsulated plastic case. The regulator controls
the dc exciter field power of conventional, 50
or 60 hertz brushless generators that have a
63 Vdc field to regulate the output voltage.

FREQUENCY (HZ.)
Frequency Compensation Curves
OVEREXCITATION SHUTDOWN
If the exciter field voltage exceeds 100 ±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. At approximately 135 ±5 Vdc, the field voltage is removed
instantaneously. Refer to the following figure.
Upon detection of overexcitation and the resulting field voltage shutdown, the regulator
will not reset or return to an operational condition until the generator output drops to less
than 6 Vac for 10 seconds minimum.
VOLT CONTROL
Rotation of VOLT control CW will increase generator output voltage.
Removing jumper (terminals 6 and 7) and connecting external potentiometer (1,000 ohms,
2 watts) allows a ±10% adjustment of voltage
range with nominal set by VOLT control.
INTERCONNECTION
Refer to the following interconnection diagrams.
a.
Connect the jumper from COM to either
the 50 Hz or 60 Hz terminal depending
upon the generator frequency.
b.
Remove the jumper and connect terminals CB– and CB+ to the CBS 305 inputs
(if used). If the CBS 305 is not being used,
leave the jumper in place.

Connect the input power to the generator stator to provide power to terminals 3
and 4. Fuse both leads. Install the optional shutdown switch, if desired.
f.
Connect the sensing input to either 240
or 480 depending on voltage. The sensing should be connected line-to-line.

Operational Test Setup
FIELD FLASHING
When the regulator is operated with the generator for the first time, the polarity of residual
magnetism may not be correct or the magnitude may not be enough. If the generator does
not build up, shut down the prime mover and
proceed as follows.
a.
With the prime mover at rest, apply a dc
source (not grounded) of not more than
48 Vdc to terminals F+ and F– in series
with a limiting resistor. Use 1 ohm of resistance for each volt from the dc source
with a power rating of at least 1 watt per
volt.
b.
Allow approximately 30 seconds before
removing the dc source.
c.
Start the prime mover and measure the
voltage at the regulator leads 3 and 4. If
the voltage is greater than 6 Vac, voltage
buildup should occur. Repeat flashing if
less than 6 Vac residual is measured.
