Technical Specifications 24VDC power supply, analog trim signal input and output. Operating temperature: -40℃ ~ +70℃. It supports small-range speed offset adjustment and comes with built-in signal filtering.
Functional Features Speed trim signal processing, setpoint fine correction, signal isolation, trim limit protection, status feedback. It prevents excessive adjustment that may cause system oscillation.
Application Scenarios Parallel generator control cabinets, gas engine speed regulation systems, grid-connected prime mover control equipment.
Performance Parameters High adjustment resolution, slow drift, stable trim response, good anti-interference performance.
Structural Characteristics Compact pluggable PCB module, with working status LED indicators and gold-plated edge connectors.
Working Principle The module converts the received trim command into a small offset signal and superimposes it on the original speed reference value. The governor adjusts the fuel or steam actuator according to the corrected reference to stabilize the unit speed.
Installation Requirements Install inside sealed control cabinet, separate trim signal wiring from high-power cables, and ensure reliable cabinet grounding.
Usage Notes Set reasonable upper and lower trim limits before commissioning, avoid large sudden trim commands to prevent unit instability.
