Functional Features F version hardware configuration, wide DC input voltage tolerance, multi‑layer electrical protection, power status LED display, high‑efficiency DC‑DC conversion, compatible with standard RX3i chassis mechanical structure.
Application Scenarios DC‑fed RX3i main or expansion rack, field equipment with 24VDC power supply, spare replacement for original F‑configured power unit.
Performance Parameters Stable DC‑DC power conversion Fast overload protection trigger Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i plug‑in rack module Front‑panel LED indicators for power and fault signals DC input wiring terminal block Backplane gold‑finger bus contact Internal F‑variant DC‑DC power circuit assembly Mechanical locking latch
Working Principle Identical working flow as IC695PSD040. External 24VDC input passes internal DC‑DC isolation and voltage‑stabilizing circuit, provides 5VDC power to chassis backplane for all plug‑in modules. F variant optimizes partial component parameters for specific project application scenarios. Protection circuit activates under abnormal electrical conditions.
Installation Requirements Mount module into dedicated power slot of RX3i chassis. Complete cabinet protective grounding. Ensure input DC voltage is within 18‑30VDC operating scope. Total rack module load power shall not surpass 40W rating. Disconnect DC input power before module change. Maintain cabinet heat‑dissipation ventilation.
Usage Notes Strictly avoid DC input reverse polarity. Do not overload backplane power output. Check LED status during regular inspection. On‑site disassembly is forbidden. Prevent dust accumulation and liquid splash.
