Model

BE350

Part Number

9166800143

INTRODUCTION
The BE350 analog voltage controller regulates voltage on a
50 or 60 hertz brushless generator. Controller features
include frequency compensation, solid-state buildup

circuitry, and EMI filtering.

CONTROLS
BE350 controls consist of jumpers and screwdriver-

adjusted potentiometers.

Potentiometer Controls
BE350 potentiometer controls are accessible through the
controller front panel and are shown in Figure 1.

This control raises and lowers the generator output voltage.

VOLT Control

This control adjusts the stability by increasing and reducing
the response time of the BE350.

STAB Control

This control adjusts the corner frequency point of the
BE350 frequency compensation characteristic.

U/F Control

Jumpers
Two jumpers control BE350 operation: the Corner

Frequency jumper and the Voltage Adjust Rheostat jumper.
These jumpers are shown in Figure 2.

BE350 controllers are delivered with the Corner Frequency
jumper set for 60 hertz operation. This gives a corner
frequency of 55 hertz. For 50 hertz operation and a corner

frequency of 45 hertz, the Corner Frequency jumper must
be move to the 50 Hz terminal.

Corner Frequency Jumper

BE350 controllers are delivered with the Voltage Adjust

Rheostat jumper connected across terminals 6 and 7. This
enables adjustment of the generator output voltage through
the controller’s internal Voltage Control potentiometer.

Clockwise rotation of the Voltage Control potentiometer
increases the generator voltage.

Voltage Adjust Rheostat Jumper

If remote adjustment of the generator output is desired, the

Voltage Adjust Rheostat jumper must be replaced with a
user-supplied rheostat. A 2000 ohm, ½ watt rheostat will
provide adequate voltage adjustment for most applications.
Figure 6 shows the proper remote rheostat connections.

INPUT POWER/SENSING INPUT
Power for the exciter field and BE350 is derived from the
generator output. The acceptable power input range is 171

to 264 Vac. Connect the input power wiring to terminals 3
and 4 as shown in Figure 5.

EXCITER FIELD POWER CIRCUIT
Controller terminal F+ is connected to the brushless exciter

field positive terminal and controller terminal F– is
connected to the brushless exciter field negative terminal.
