- Standard DIN‑rail clip mounting for cabinet installation, fast assembly and replacement.
- LED status indicator shows power supply health status for quick on‑site troubleshooting.
- Compact housing design, occupies minimal cabinet installation space. Application Scenarios: Power supply for 990 and 991 series two‑wire transmitters; auxiliary power for local field junction boxes; power source for small‑scale vibration monitoring systems; redundant power feeding for critical rotating machinery protection instrument cabinets. Performance Parameters: Output voltage accuracy ±1%; load regulation ≤1%; line regulation ≤0.5%; protection response time less than 100 ms; high MTBF value for continuous industrial operation. Material Composition: Flame‑retardant engineering plastic housing; high‑frequency switching transformer; multi‑layer PCB circuit board; solid‑state power semiconductor components; metal DIN‑rail spring clip; screw terminal blocks. Structural Characteristics: Rectangular DIN‑rail housing; front‑side status LED indicator; top‑and‑bottom screw terminal blocks for input and output wiring; rear spring‑loaded DIN‑rail locking clip; housing surface printed with model, electrical rating and safety marking. Working Principle: AC input goes through EMI filtering and rectification circuit, converted into DC for high‑frequency switching circuit. High‑frequency transformer performs voltage isolation and transformation. Post‑stage rectifier‑filter circuit outputs stable regulated 24 VDC. Onboard feedback loop dynamically adjusts switching cycle to maintain constant output voltage under input fluctuation and load variation. Protection circuits continuously monitor output condition and trigger shutdown upon fault events. Installation Requirements:
- Snap module firmly onto standard 35 mm DIN‑rail, confirm rear locking clip fully engaged.
- Strictly distinguish AC input terminals and DC output terminals, avoid mis‑wiring damage.
- Maintain adequate ventilation clearance around module, do not block heat dissipation area.
- When implementing redundant parallel configuration, follow official parallel wiring specification.
- Use correct wire gauge for terminals, fasten terminal screws tightly to prevent loose contact and over‑heating. Usage Notes:
- Do not exceed rated output power and maximum output current. Overload will trigger protection or permanent module damage.
- Do not install in environment beyond specified operating temperature range. High ambient temperature reduces service life.
- Avoid moisture, dust and conductive debris accumulation inside power‑supply housing.
- Before power‑on, double‑check wiring correctness to prevent reverse connection or cross‑connection.
- Redundant parallel configuration requires strictly following manufacturer specification, arbitrary parallel operation is prohibited.
