Introduction and Functional Description
Caution:
Read This Installation
Manual Carefully and Entirely!
Warning:
Do not use digital equipment to read voltage, Hz, or amperage
during this installation. Use only Analog sensing equipment! Failure to do so
may result in damage to equipment or in personal injury!
ALWAYS
perform all setup procedures off-line
ALWAYS
wear eye protection
ALWAYS
strip wire insulation properly or use insulated connectors
ALWAYS
use analog metering equipment when setting up the regulator
ALWAYS
ensure the regulator receives ample airflow
ALWAYS
use adequate fusing
NEVER
hold the regulator in your hand when energized
NEVER
install the regulator in a place it can get wet or is exposed to the elements
NEVER
mount the regulator over a screw, bolt, rivet, welding seam, or other fastener
NEVER
remove the regulator cover while the unit is in operation
NEVER
insert a screwdriver or other object under the regulator or SE350 cover
NEVER
touch any exposed part of the SE350 during operation
NEVER
install a switch in the DC portion of the regulator’s wiring
NEVER USE A DIGITAL FREQUENCY METER
(It
can give a false reading
!)
Functional Description
The SE350 Static Exciter Module has a proven track record of over 20 years of extreme
reliability and robustness. It offers an inexpensive and unique way to upgrade a
standard voltage regulator to a miniature static exciter with a minimum of connections
and a minimum of installation space.
The SE350 is designed to work with Power-Tronics UVR and XR series voltage
regulators and UVR, XR, and PC series phase controllers. Coupled with one of these
products, the SE350 allows field excitation of 105VDC at 25ADC for a single unit, or
105VDC at 50ADC for tandem units.
Regulation accuracy depends on the voltage regulator the SE350 is used with. If used
with the XR500D series Universal Voltage Regulator, the voltage regulation will be
/-.25%. Other voltage regulators will regulate within their printed specifications.
The SE350 does not contain internal fusing and must be fused externally.
Always use 25A 250VAC fast-blow fuses with the SE350 Static Exciter Module!
