Material Composition Metal‑plastic composite rack‑mount housing. Internal multilayer glass‑fiber epoxy printed circuit boards set. Industrial‑grade main processor, high‑precision sampling modules. Screw‑type high‑density signal terminals, communication ports and power supply terminals.
Structural Characteristics Standard 19‑inch rack‑mount controller structure. Front panel is equipped with LED status indicators, operation keys and communication ports. Rear panel arranges power supply, analog sampling, pulse output and signal wiring terminals.
Working Principle After power‑on, controller finishes hardware self‑check and parameter loading. It continuously collects generator voltage and current feedback signals. Main processor executes excitation regulation algorithm according to set control parameters, outputs trigger pulse to adjust thyristor conduction angle, so as to realize closed‑loop adjustment of generator excitation current. Operating data and fault events are stored locally, meanwhile uploaded to upper monitoring system through communication interface.
Installation Requirements Mount UNITROL1000 onto standard 19‑inch cabinet rack and fasten fixing screws. Complete auxiliary power supply, analog sampling, pulse output and communication wiring strictly following engineering schematic.
