Technical Specifications Multi‑slot back‑plane bus; Power input:88‑300V DC /96‑250V AC; Max power dissipation:60VA Operating temperature:‑40℃~+70℃; Storage temperature:‑40℃~+85℃; Humidity:5‑95% non‑condensing Mounting:rack plug‑in mounting
Functional Features Supports multiple plug‑in sub‑modules. Distributes operating power. Realizes high‑speed back‑plane data exchange. Mechanical locking for each inserted module.
Application Scenarios Hardware base for UR generator, transformer and feeder relays. Spare replacement chassis for substation relay maintenance.
Performance Parameters Stable high‑speed back‑plane transmission. Reliable multi‑module power distribution. Good anti‑vibration mechanical performance.
Material Composition Metal rack housing. Gold‑plated connector multilayer epoxy back‑plane PCB. Power distribution circuits, metal locking hardware, rear power terminals.
Structural Characteristics Standard rack plug‑in structure. Rear gold‑plated slot connectors for sub‑cards. Front locking screws for rack fixation. Rear terminals for auxiliary power input.
Working Principle Auxiliary power feeds rear terminals and distributes to slots via back‑plane circuits. Inserted modules get power and data interconnection from gold‑plated bus connectors.
Installation Requirements Cut rack power before replacement. Insert chassis into rack slot and tighten front screws. Install required sub‑modules. Connect power wiring. Restore power and verify module communication.
Usage Notes Hot‑swap under powered status is prohibited. Keep connector contacts clean. Apply anti‑static procedures during module insertion.
