Working Principle External 24VDC power is connected to module input terminals. Internal high‑power DC‑DC circuit completes isolation and voltage stabilization, outputs 5VDC high‑current power to RX3i chassis backplane, supplies power for all installed modules. Multi‑protection mechanism cuts off output automatically under overload, short‑circuit or over‑temperature faults.
Installation Requirements Insert module into dedicated high‑power power slot of RX3i chassis. Complete reliable cabinet protective grounding. Strictly prevent DC input reverse polarity. Calculate total power consumption of all rack modules and cannot exceed 140W rated power. Disconnect DC input power before module replacement. Keep cabinet ventilation channels unobstructed for heat dissipation.
Usage Notes Total rack load must not exceed rated 140W output capacity. Use adequate cross‑section power wiring for DC input loop. Monitor LED status for power system diagnosis. Forbid on‑site disassembly of internal power hardware. Avoid corrosive gas and liquid splash.
