SE3000B-3P
3-Phase Static Exciter
The Power-Tronics SE3000B-3P 3-Phase
Static Exciter is a self-contained complete
Static Exciter. The SE3000B-3P 3-Phase
Static Exciter is designed for continuous
operation at up to 250vdc at 300adc!
The SE3000B-3P is uniquely designed to
sit in a compact footprint while being
passively convection cooled for a long
service life. Because of its unique
modular design, the SE3000B-3P
minimizes downtime should a repair ever
be necessary! The SE3000B-3P's
compact design allows a wide variety of
installation methods, including installations
where space is at a premium.
The SE3000B-3P is a time-proven design,
utilizing high-reliability components and a
unique modular design to simplify repair.
This product also features loss of sensing
protection. If the sensing voltage is lost,
the unit will shut down to prevent
catastrophic damage caused by runaway
voltage!
The SE3000B-3P is also capable of
parallel operation with other generators or
with a utility buss. Power-Tronics' wide
variety of optional accessories also allows
the SE3000B-3P to be remotely operated
by dry contact switching or by a PLC
controller!
The SE3000B-3P is designed to provide a
lifetime of service and is specifically built to
minimize failures and potential downtime!

    SERCP-3P Removable Control Panel The SE3000B-3P 3-Phase Static Exciter features a removable control panel for convenient relocation of the control module and firing module to a location closer to the main switchboard and can be configured to meet the needs of your application. The...
  • Page 10 To detach the removable control panel from the SE3000B-3P, simply remove the 4 1/4- 20 nuts that hold it to the main chassis and remove the wires from TB1 and TB2. Install the control panel in the desired location, and then reconnect the wiring as originally shown.

  • Page 11: Initial Setup And Commissioning

    Initial Setup and Commissioning Install the SE3000B-3P and wire up to the correct wiring diagram (Standard hookup, or optional internal UIC200). If installing the SE3000B-3P on a brush-type generator, verify that the brushes and brush riggings are isolated, ungrounded, and connected ONLY to the SE3000B-3P.
