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 exciter
ALWAYS ensure the exciter receives ample airflow
ALWAYS use adequate fusing
NEVER hold the regulator in your hand when energized
NEVER install the exciter in a place it can get wet or is exposed to the elements
NEVER mount the exciter over a screw, bolt, rivet, welding seam, or other fastener
NEVER insert a screwdriver or other object into any part of the SEM100A
NEVER touch any exposed part of the SEM100A during operation
NEVER install a switch in the DC portion of the exciter’s wiring
NEVER USE A DIGITAL FREQUENCY METER (It can give a false reading !)
Functional Description
The SEM100A 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 reduced size static exciter with a minimum of
connections and a minimum of installation space.
The SEM100A 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 SEM100A allows field excitation of 105VDC at 90ADC continuous.
Regulation accuracy depends on the voltage regulator the SEM100A 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 SEM100A does not contain internal fusing and must be fused externally.
Always use 100A 250VAC fast-blow fuses (such as JJN or Type J fuses) with the
SEM100A Static Exciter Module! Failure to fuse the SEM100A properly will void
your warranty!
