Technical Specifications Command input interface from main control unit, multi‑channel pulse trigger output terminals, power unit status feedback input, auxiliary 24 V DC control power supply. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Circuit board surface with conformal coating for harsh cabinet environment protection.
Functional Features Receives firing angle setpoint command from main control board. Generates accurate phase‑matched trigger pulse signals. Amplifies pulse output capacity to satisfy thyristor gate trigger requirement. Collects power unit running status and fault feedback signals. Carries out hardware self‑diagnosis for pulse channel open‑circuit and short‑circuit failures.
Application Scenarios Spare pulse trigger board for generator excitation cabinet and industrial high‑power rectifier equipment. Widely used in thermal power, hydropower and metallurgy power conversion equipment maintenance.
Performance Parameters High‑precision phase synchronization for pulse generation. Stable pulse driving output capability. Real‑time fault signal acquisition and transmission performance.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Pulse logic generation circuit, pulse power amplification assemblies, status signal conditioning circuit. Multi‑pin plug‑in connectors and metal screw mounting hardware. Conformal protective coating layer.
Structural Characteristics Rectangular circuit‑board layout. Multiple reserved screw mounting holes for cabinet bracket fixation. Low‑voltage logic circuit zone and high‑energy pulse output zone keep clear layout separation.
Working Principle UPC090AE01 obtains auxiliary DC control power supply. Corresponding phase‑aligned trigger pulses are generated and amplified, then sent to thyristor gate terminals. Feedback signals from power units are conditioned and transmitted back to main control board for system fault judgment.
Installation Requirements Fasten circuit board to cabinet mounting bracket with mounting screws. Fully insert and lock all plug‑in connectors. Restore auxiliary control power, complete pulse simulation test before switching on high‑voltage loop.
