Application Scenarios: Petrochemical SIS rack power supply, emergency shutdown system power unit, power‑plant safety control rack power supply, offshore platform safety instrument system power supply, all Trusted platform rack redundant power deployment projects.
Material Composition:
- Module housing: Metal alloy heavy‑duty heat‑dissipating enclosure
- Internal circuit: Industrial power conversion PCB board, high‑power DC‑DC switching components
- Input‑output connection: High‑current screw‑locking power terminal blocks
- Backplane connector: High‑current rated 96‑pin backplane contact assembly
- Fastening parts: Stainless steel anti‑vibration locking screws
Structural Characteristics: Larger‑size standard Trusted rack power module form factor. Front‑panel arranges power terminals and status LED indicators. Rear‑side high‑current 96‑pin backplane connector delivers regulated power to rack backplane bus. Integrated metal housing acts as heat‑dissipation structure for power conversion components. Fixed‑screw locking mechanism fixes module firmly inside power slot.
Working Principle: Field wide‑range DC input power enters T9802 input terminal block. Internal DC‑DC conversion circuit stabilizes variable input voltage into precise 24 VDC regulated output power. Output power feeds to rack backplane bus to supply power for all controller and I/O modules. Multiple T9802 modules realize current sharing parallel operation. On‑board monitoring circuit continuously samples input voltage, output voltage, output current and internal component temperature. Protection circuit activates immediately when abnormal electrical or thermal condition is detected, meanwhile fault status is reported to Trusted main processor.
Installation Requirements:
- Mount T9802 module into dedicated power slot of Trusted rack.
- Tighten front‑panel fixing screws with specified torque value to ensure backplane full contact.
- Use high‑current rated field power cables for input power wiring. Strictly follow terminal polarity marking.
- For redundant power configuration, feed independent field power sources to each module.
- Connect rack protective earth terminal to plant safety grounding busbar reliably. Reserve sufficient rear‑side air flow space for module heat dissipation.
Usage Notes:
- Do not exceed module maximum output power and output current rating. Over‑load activates protection or permanently damages power components.
- Redundant parallel application must use multiple independent field power sources. Do not feed single power source to all redundant power modules.
- Check input polarity before power‑on. Reverse input polarity triggers input protection.
- Keep ventilation path unobstructed. Blocked air‑flow causes over‑temperature protection and power output shutdown.
- Hot‑swap replacement can be executed while rack remains powered‑on, follow official operation manual procedures.
