Functional Features Support multiple power‑supply modules N+1 redundant parallel hot‑standby operation. Hardware protection for over‑voltage, over‑current, short‑circuit and over‑temperature condition. Support hot‑swap online replacement without powering‑off whole rack. Front‑panel LED indicators for power good, fault and over‑temperature alarm. Continuous monitoring of output voltage and internal temperature. Fault status signal reported to main processor through TriBus backplane bus. High‑efficiency power‑conversion circuit adapted to industrial cabinet environment.
Application Scenarios Power source for Tricon SIS safety controller rack. Power supply for emergency‑shutdown system cabinets in petrochemical and oil‑gas industry. Power supply for power‑plant safety‑interlock‑system control rack. Redundant power‑supply configuration for fire‑and‑gas monitoring system cabinet. All Tricon series safety‑instrumented‑system rack internal module power feeding.
Performance Parameters Redundancy Operation: N+1 redundant parallel operation without output disturbance during single‑module failure Conversion Efficiency: High power‑conversion efficiency under full‑load and partial‑load condition Protection Response: Fast hardware‑level protection response under abnormal power condition Hold‑up Time: Maintain output hold‑up under momentary input power interruption
Material Composition Internal power‑conversion printed circuit board with conformal anti‑corrosion coating. Outer housing: Metal alloy protective casing with integrated heat‑dissipation structure. Input‑output connector assemblies: Industrial‑grade power terminals. Internal components: High‑reliability power conversion devices, filter components, protection circuits. Mounting hardware: Anti‑vibration metal locking fasteners.
Structural Characteristics Special‑slot plug‑in structure for Tricon rack power‑supply compartment. Front‑panel power input terminals and status LED indicator group. Built‑in metal heat‑dissipation structure for power‑conversion components. Back‑plane power distribution contact for supplying power to rack internal backplane. Mechanical locking mechanism to secure module in rack slot.
Working Principle External AC power accesses module input terminals. Internal filter circuit suppresses power‑grid surge and electromagnetic interference. Power conversion circuit converts input AC power into stable 5 VDC and auxiliary 24 VDC for rack internal modules. Hardware monitoring circuit detects output voltage, output current and internal module real‑time temperature. When over‑voltage, over‑current or over‑temperature happens, protection circuit triggers shutdown action to avoid damage to downstream modules. Multiple power‑supply modules run in parallel redundant mode. Fault of single power‑supply module will not affect rack continuous power supply, and fault information is uploaded to main processor through backplane bus.
Installation Requirements Insert power‑supply module into dedicated power‑supply slot of Tricon rack chassis. Input power wiring must use cables satisfying current‑carrying capacity requirement. Implement reliable protective grounding for rack and power‑supply module housing. Configure redundant power‑supply modules according to system design requirement. Hot‑swap replacement shall comply strictly with site safety operation procedure. Ensure cabinet ventilation channel is unobstructed for power‑supply heat dissipation. Cabinet ambient temperature must stay within rated operating range.
