Main Functions

AC‑to‑DC regulated power conversion: Accept wide‑range AC mains input (85‑264 VAC), convert AC power into multiple groups of stable regulated DC power for UCN controller backplane, CPU boards, I/O modules and communication circuit boards inside the cabinet.
Backup battery charging management: Build‑in 48 V battery charging circuit; charge external backup battery pack under normal mains power condition. When AC power fails, it switches to battery power supply to maintain continuous DCS operation.
Redundant parallel operation support: Multiple identical power modules can be connected in parallel for N+1 redundant power configuration. Single‑module failure will not interrupt system power supply, improve overall system availability.More products: www.plcva.com

HONEYWELL 51198947‑100 (SP724‑Y01A) HPM Power Supply Module

Multi‑layer electrical protection: Integrate over‑voltage, under‑voltage, over‑current, over‑temperature and short‑circuit protection mechanisms. Automatically cut off output under abnormal conditions to avoid damage to downstream DCS circuit boards.
Real‑time status monitoring & fault diagnosis: Equipped with multi‑LED status indicators for AC‑IN, DC‑OUT, battery status, fan/temperature and fault alarm. Feed power‑supply health signals to UCN host controller for system‑level alarm logging and remote diagnosis.
Auxiliary frequency‑synchronization signal output: Provide 6VAC 50/60Hz line‑frequency synchronous auxiliary output, used for system internal clock and logic synchronization of control equipment..
Industrial‑grade environmental adaptability: Designed for control cabinet installation; operating temperature range ‑20 ℃ ~ +55 ℃, derating allowed up to 65 ℃; anti‑surge and anti‑EMI design for chemical, power‑plant harsh electromagnetic‑interference environments.
