Description
Original DSEA109 (pre-MKII, legacy service).
Did you know
- The Deep Sea Electronics DSEA109 Digital Automatic Voltage Regulator (AVR) was introduced on July 1, 2019, as a new addition to DSE's Genset brand AVR family.
- The DSEA109 is a digital AVR, designed to replace the complexities of older analog AVR designs. It offers advanced features compared to simpler modules like the DSE103 MKII, which is a speed switch control module rather than an AVR.
- The DSEA109 is chosen for its ability to maintain a smooth, stable, and regulated AC output voltage regardless of the electrical load, overcoming the temperature sensitivity of analog AVRs. Its advanced features, including CAN (J1939) communications, soft start ramping, and remote voltage adjustment, make it suitable for synchronizing and load-sharing applications.
| Model | Type | Power Supply Input | Voltage Regulation Accuracy | CAN (J1939) Communications | Excitation Output Current (Continuous) |
|---|---|---|---|---|---|
| DSEA109 | Digital Automatic Voltage Regulator (AVR) | Self Excited (Shunt), Auxiliary Winding or PMG (Single Phase or 3 Phase) | ±0.5 % | Yes | 0 A DC to 7 A DC |
| DSE103 MKII | Speed Switch Control Module | 8 V to 35 V DC Continuous | N/A (Speed Control) | No | N/A (Relay Outputs) |
