Technical Specifications AC mains input range, multiple regulated DC output channels, rack back‑plane power distribution connector. Operating ambient temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. Built‑in over‑voltage, over‑current and over‑temperature protection. Rack plug‑in mechanical form.
Functional Features Converts AC input power to multi‑rail regulated DC outputs for rack‑mounted control hardware. Delivers power to rack back‑plane bus for all inserted modules. Executes hardware protective shutdown under over‑voltage, over‑current and over‑temperature conditions. Provides power‑good status signal for upper‑level system diagnosis. Runs automatic hardware self‑test upon power‑on.
Application Scenarios Primary power supply spare for GE rack‑based automation systems, applied for maintenance in power plants, petrochemical and heavy‑manufacturing industrial sites.
Performance Parameters Wide AC input tolerance, stable DC output regulation, low output ripple, rapid fault protection response, continuous full‑load operation performance.
Material Composition Metal flame‑retardant module housing. AC‑DC switching conversion circuit board, power semiconductors, high‑voltage capacitors, isolation magnetic components. Gold‑plated back‑plane contact connectors. Rack locking latch assembly.
Structural Characteristics Standard rack plug‑in module dimension. Rear gold‑plated connector connects with rack back‑plane power bus. Front panel mounts status LED indicators and locking latch. Internal physical separation between high‑voltage AC input section and low‑voltage DC output section.
Working Principle AC mains input passes through EMI filter and rectification circuit. Switching conversion stage generates isolated stabilized DC output voltages. Regulated power is distributed through back‑plane connector to supply all rack modules. On‑board monitoring circuit tracks output voltage, load current and internal temperature, triggers protective shutdown when abnormal condition occurs.
Installation Requirements Verify full rear‑plane connector engagement. Re‑apply AC input power, observe power‑good LED status and complete rack‑wide power‑on self‑test.
Usage Notes Input AC voltage must conform to rated specification. Hot‑swap under powered condition is strictly forbidden. Keep rack ventilation channels unblocked for thermal dissipation.
