24VDC power supply, magnetic pickup speed signal input, proportional actuator drive output. Operating temperature: -40℃ ~ +70℃.
Functional Features
Closed-loop PID speed regulation, overspeed alarm and trip protection, startup fuel limiting, fault self-diagnosis and power-off parameter retention.
Application Scenarios
Land standby generator sets, industrial water pump prime movers and stationary power units.
Performance Parameters
Smooth dynamic adjustment, small steady-state speed deviation, good compatibility with different actuators.
Structural Characteristics
Compact panel-mounted controller, wiring terminal block, running, alarm and fault LED indicators.
Working Principle
The controller converts pulse signals from the magnetic pickup into actual speed values, compares them with the preset speed setpoint, and adjusts output current to change the fuel actuator position.
Installation Requirements
Install on a shock-absorbing bracket, use shielded twisted-pair cables for speed sensor wiring.
Usage Notes
Calibrate actuator stroke before commissioning, do not modify the overspeed protection threshold arbitrarily.
