INTRODUCTION
The SE350E voltage regulator is an encapsulated electronic
voltage regulator which controls the output of a brushless AC
generator by regulating the current into the exciter field.

INSTALLATION
MOUNTING
The SE350E voltage regulator can be mounted in any plane.
See Figure 1 for mounting dimensions.
Figure 1
EXCITER POWER CIRCUIT
Connect the regulator wire F+ to the generator F+ or F1 field
terminal. Connect the regulator wire F- to the generator F- or
F2 field terminal. See Figure 2 for typical connection diagram.
Figure 2
SENSING / POWER INPUT CIRCUIT
Input power and sensing is achieved through terminals 3 and
4.
The voltage input requirement of the SE350E is 190 to
240 vac.
See Figure 2 for typical connection diagram.
FUSE
A 4 Amp 250V - 5 X 20 mm fuse is supplied with the
regulator (Part A-527066).
TO PREVENT PERSONAL INJURY OR EQUIPMENT
DAMAGE, ONLY QUALIFIED PERSONNEL SHOULD
INSTALL, OPERATE, OR SERVICE THIS DEVICE.
DO NOT megger or high-pot the generator
with the regulator connected. DO NOT high-pot the regulator.
