The Hyundai HDEC1000 Version 1.12 is a high-precision digital excitation controller designed for synchronous generators and motors. Utilizing advanced digital signal processing, this unit provides stable voltage regulation through multiple modes including AVR, FCR, and Reactive Power control. It is engineered for heavy-duty marine and industrial power generation environments, featuring robust hardware for reliable soft-start sequences and comprehensive protection against over-excitation or under-excitation conditions.

Product Q&A

Q: What are the primary differences between HDEC1000 Version 1.12 and 1.13? A: Version 1.12 and 1.13 are functionally compatible; however, Ver 1.13 often includes minor firmware optimizations for communication stability and expanded Modbus register mapping.

Q: Can the HDEC1000 be used for both 110V and 460V sensing? A: The base unit supports different sensing ranges, but the specific configuration (such as P1302 or P1402 variants) determines the hardware factory setting for 110VAC or 460VAC sensing. Always verify the label before installation.

Q: Does this regulator support parallel operation with other generators? A: Yes, the HDEC1000 includes integrated droop compensation and reactive power sharing functions, allowing it to manage load distribution when multiple synchronous machines are connected to a single bus.
