Functional Features: Wide‑range AC input automatic adaptation; stable constant‑voltage DC output; built‑in over‑voltage, over‑current, short‑circuit and over‑temperature hardware protection; fault relay contact for remote alarm output; LED indicator shows power‑on status and fault state; surge suppression circuit restrains power‑grid transient impact; automatic recovery after short‑circuit fault elimination.
Application Scenarios: Metso MaxDNA DCS control cabinet internal power supply; pulp and paper mill process control cabinet power unit; thermal power plant auxiliary system control cabinet; chemical plant small‑scale unit automation cabinet; water‑treatment plant DCS cabinet power supply system.
Performance Parameters: Output voltage fluctuation less than ±1 %; low output ripple noise; fast response for input voltage fluctuation; comply with industrial EMC anti‑interference standards; realize 7×24 hours uninterrupted continuous operation.
Material Composition: Cold‑rolled steel metal shell with anti‑rust spraying treatment; high‑frequency switching transformer; industrial electrolytic capacitor; fiberglass epoxy PCB; surge‑suppression components; plastic insulated wiring terminal; metal ventilation mesh.
Structural Features: Compact rectangular box‑type structure; metal DIN‑rail buckle installed at bottom of shell; front panel equipped with AC input terminal, DC output terminal and alarm signal terminal; top and side surfaces arranged with dense ventilation mesh for heat dissipation; LED status indicators distributed on front panel; internal circuit completes physical isolation between high‑voltage input area and low‑voltage output area.
Working Principle: Alternating‑current power enters module from input terminal, passes through EMI filter and surge suppression circuit, and then enters high‑frequency switching circuit. After high‑frequency transformer transformation, rectification and filtering, stable 24 VDC direct‑current power outputs to rack load. Internal real‑time monitoring circuit detects output voltage, output current and internal temperature. When abnormal condition triggers protection mechanism, alarm relay contact changes state and sends fault signal to upper monitoring system.
Installation Requirements: Fix IOP382 firmly on standard 35 mm DIN‑rail inside control cabinet. Ensure metal buckle locks tightly without displacement. AC input wiring selects cables matching rated input current. Alarm signal wiring connects to DCS digital input channel. Shell protective grounding terminal connects reliably to cabinet protective ground. Keep sufficient ventilation clearance around module, prohibit installing adjacent to high‑heat power components.
Precautions for Use: Cut off AC input power before wiring operation. Do not exceed rated output load capacity. Confirm input AC voltage scope before power‑on. Do not block ventilation mesh on shell surface. Inspect wiring terminal tightness regularly. Do not open metal shell in power‑on status. Avoid cabinet internal condensation.
