The DSEA109 Digital Automatic Voltage Regulator (AVR) with CAN is designed to regulate the output voltage of an AC alternator. The DSEA109 is supplied by either a 3 phase PMG, single phase PMG, stator auxiliary winding or a shunt system taking power from the output windings.
The DSEA109 eliminates the complexities involved with analogue AVR designs. Analogue AVR designs can be over sensitive to changes in temperature which affects stability whereas the DSEA109 AVR maintains a smooth, stable regulated AC output voltage, regardless of the electrical load connected.The DSEA109 also features 3-phase sensing for better regulation.
Please Note: The DSE815 interface is required for programming.
The DSEA109 is simple to install and set up using either the DSE Configuration Suite PC Software and the DSE815 configuration interface or five onboard potentiometers and 4 DIP switches, combined with a status LED providing a simple user interface.
The DSEA109 Digital AVR has numerous advanced features such as a CAN port providing J1939 communications, soft start ramping, connection for a quadrature droop CT and the ability to perform remote voltage adjustment, making it perfect for synchronising and load sharing applications. The DSEA109 Digital AVR is an ideal option for both OEM and retro-fit solutions.
