This compact and reliable voltage regulator is mainly intended for small generators and industrial synchronous machines. The maximum output current for continuous operation is 15 A dc. The most advanced microprocessor technology together with IGBT semiconductors allows it to be used in all conceivable application areas.
Main features:
- Automatic voltage control (digital) with adjustable PID controller
- Power factor and reactive current controller with PID control algorithm
- Excitation current regulator (manual control) with PI control
- Various limiter and protection functions
- Reactive power sharing for generators connected in parallel
- Commissioning and Maintenance Tool CMT 1000
- Voltage matching prior to synchronization
- Serial communication (MODBUS)
Optional functions:
- Automatic synchronization
- Synchrocheck function
- Monitoring of rotating diodes
- Power System Stabilizer according to IEEE PSS 2A/2B
- Enhanced monitoring functions, e.g. PT monitoring
- Setpoint follow-up based on CAN communication, intended for redundant systems
- External power module for 40 A dc continuous output current
Extension of the Excitation Current capability up to 40 A (continuously) using the UNITROL 1000-PM40 module
UNITROL 1000-PM40 is a microprocessor-controlled chopper with IGBT semiconductors. It is connected to a UNITROL 1000-15 AVR by CAN bus. This combination is called "UNITROL 1000-40" and it allows excitation field currents up to 40 A.
Light-emitting diodes (LEDs) on the front plate of the UNITROL 1000-PM40 provide the most important status information.
Additional settings or commissioning of UNITROL 1000-PM40 module is not required, since the power stage is automatically configured by the UNITROL 1000-15 module.
UNITROL 1000-40 is a perfect solution for retrofit applications where field current between 15 A and 40 A is required.
