Performance Parameters: Output voltage fluctuation less than ±1 %; low output ripple noise; rapid response for input voltage fluctuation; withstand industrial electromagnetic interference conforming to IEC61000 series standards; 7×24 hours uninterrupted running capability; output load short‑circuit auto‑recovery function.
Material Composition: Metal steel sheet outer shell with anti‑rust spraying treatment; high‑frequency switching transformer; industrial‑grade electrolytic capacitor; fiberglass epoxy multilayer PCB; thermistor over‑temperature sensing component; plastic insulated terminal block; ventilation mesh metal cover.
Structural Features: Compact rectangular box‑type structure; standard DIN‑rail metal buckle installed at bottom of shell; front panel equipped with input‑output wiring terminals and alarm signal terminals; top surface designed with dense ventilation mesh for heat dissipation; LED status indicators arranged on front face; internal circuit separates high‑voltage input area and low‑voltage output area for physical isolation.
Working Principle: Alternating‑current power enters module from input terminal, passes through filter and surge suppression circuit, then goes to high‑frequency switching circuit. After high‑frequency transformer voltage transformation and rectification filtering, stable 28 VDC direct‑current power outputs to external load. Internal monitoring circuit detects output voltage, output current and internal temperature in real‑time. When abnormal status occurs, protection circuit activates and alarm relay contact changes state to send fault signal to upper monitoring system.
Installation Requirements: Mount module firmly on standard 35 mm DIN‑rail inside control cabinet. Ensure metal buckle locks tightly without displacement. Input power wiring must adopt cables matching rated current. Connect alarm signal wiring to DCS digital input channel. Shell protective grounding terminal connects reliably to cabinet protective ground. Maintain 20 mm‑30 mm ventilation clearance on upper and lower sides of module. Do not install adjacent to high‑heat generating equipment.
Precautions for Use: Cut off AC input power before wiring operation. Strictly prohibit exceeding rated output current load. Do not connect wrong input AC voltage. Keep cabinet internal environment without condensation. Do not block ventilation mesh on shell surface. Inspect wiring terminal tightness periodically. Wear anti‑static wrist strap when opening shell for maintenance.
