Digital Automatic Voltage Regulators (AVR)
DSEA109
Digital Automatic Voltage Regulator (AVR) with CAN Communications & PMG Support
The DSEA109 Digital Automatic Voltage Regulator (AVR) is designed to regulate the output voltage of an AC generator. The DSEA109 is supplied by either a Permanent Magnet Generator (PMG), stator auxiliary winding or self excited from the generator’s main stator windings (shunt).
The DSEA109 eliminates the complexities involved with analogue AVR designs. Analogue AVR designs can be oversensitive to change in temperature which affects the generators output voltage stability, where as the DSEA109 AVR maintains a smooth, stable regulated AC output voltage, regardless of the electrical load connected. The DSEA109 also features 3 phase generator terminal sensing for better regulation.
The DSEA109 is simple to install and set up using the DSE Configuration Suite PC Software with the DSE815 configuration interface. On board DIP switches and potentiometers can be used to further adjust the selected configuration and set points within the AVR at a later date by on site maintenance engineers.
The DSEA109 has numerous advanced features such as a CAN port providing J1939 communications. This allows the AVR to be connected to supported DSE modules to display AVR instrumentation, and send control commands such as voltage adjustment and configuration selection. In addition to this, the DSEA109 also provides a soft start ramping feature, connection for a droop CT and the ability to perform remote voltage set point adjustment. All of these feature make it perfect for synchronising and loadsharing applications.
The DSEA109 AVR is an ideal option for both OEM and retro-fit solutions and is a suitable aftermarket replacement for multiple OEM AVR products.
