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 static exciter receives ample airflow
ALWAYS use adequate fusing
NEVER hold the static exciter in your hand or lap when energized
NEVER install the static exciter in a place it can get wet or is exposed to the elements
NEVER mount the static exciter over a screw, bolt, rivet, 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 cover
NEVER touch any exposed part of the SE3000B-3P during operation (LIVE HEATSINKS)
NEVER install a switch in the DC portion of the static exciter’s wiring
NEVER USE A DIGITAL FREQUENCY METER (It can give a false reading!)
Functional Description
The SE3000B-3P 3-Phase Static Exciter is the result of over 20 years of engineering efforts and offers
high-demand features at a competitive price point. The SE3000B-3P is a proven design and is
engineered to greatly simplify setup while offering extreme reliability. When properly installed, the
SE3000B-3P 3-Phase Static Exciter is designed to provide a lifetime of service.
A Generator voltage regulator has several automated tasks it must perform in order to provide reliable,
clean, and regulated electricity. It must regulate the terminal voltage within its design specifications
and protect both itself and the generator should a fault situation arise.
The SE3000B-3P 3-Phase Static Exciter is designed to replace older obsolete static exciters or
rotating exciters with a minimum of connections and a minimum of required installation space. The
SE3000B-3P 3-Phase Static Exciter contains an internal filter for voltage sensing, internal field-
replaceable 300A fusing, and internal DC field noise suppression. The SE3000B-3P is also designed
to be user-serviceable should a problem arise. Fuse or rectifier replacement in the field takes only
minutes, thanks to the unique modular design of the SE3000B-3P.
The SE3000B-3P features loss of sensing protection and will shut down if sensing voltage is lost. This
feature prevents a runaway condition prevalent in many separate-sensing designs and will result in a
fail-safe shutdown!
Due to its extreme simplicity, the SE3000B-3P 3-Phase Static Exciter is uncommonly reliable and
offers features and regulation accuracy usually only offered by much more complicated and often
much more expensive static exciters.
