Time‑synchronization signal interface: IRIG‑B. Operating Temperature:‑40 °C to +70 °C Storage Temperature:‑55 °C to +85 °C Relative Humidity:5%‑95%, non‑condensing Mechanical Dimension: Standard full‑height single‑slot rack‑plug‑in module Certifications: CE, UL

Functional Features Multi‑channel isolated DC power output for protection‑relay rack modules. IRIG‑B time‑code synchronization signal distribution for rack‑internal devices. Built‑in over‑voltage, over‑current and short‑circuit fault protection. Front‑panel LED status indicators for power and fault diagnosis. Rack‑plug‑in mechanical structure supports hot‑swap replacement operation.

Application Scenarios Multilin protection‑relay rack systems in power‑plant substations. Industrial‑grid relay‑protection control room cabinet equipment. Multi‑device time‑synchronization industrial‑automation control systems. Petrochemical plant electrical‑protection rack power‑supply positions.

Performance Parameters Minimum power‑supply conversion efficiency: 88%. Time‑synchronization distribution accuracy: ±1 µs. Output‑voltage regulation precision: ±1%. Input‑to‑output isolation voltage:2500 VAC.

Structural Characteristics Standard single‑slot rack‑plug‑in metal‑shielded housing. Front‑panel LED status indicator lamps for power, fault and synchronization status. Rear‑side backplane‑interconnection golden‑finger interface. Captive anti‑loosening locking screws for rack fastening installation.

Working Principle AC input voltage passes through EMI filter circuit and high‑frequency switching‑power‑supply conversion circuit. Multiple groups of galvanically isolated stable DC power outputs are generated for rack‑load modules. External IRIG‑B time‑code reference signal is received, processed and distributed to each relay unit via rack backplane bus. On‑board diagnostic circuit monitors power‑supply output status and synchronization signal quality continuously.

Installation Requirements Insert into designated slot position of GE standard relay‑system rack. Fasten captive locking screws to specified torque value. Complete rack‑system protective‑grounding connection strictly according to system specification. Connect external IRIG‑B time‑source signal cable following official engineering drawing. Calculate total load power consumption of rack modules, ensure total load does not exceed SPS5710 rated output power capacity.
