What this product is
What this product is
A 1U ultra-compact modular DC power conversion unit featuring active Power Factor Correction (PFC) and isolated DC-DC stages, encased in a heavy-duty extruded aluminum heatsink for passive heat dissipation without rotating fans.
What problem it solves
Eliminates high failure rates caused by fan mechanical wear, dust accumulation, and acoustic noise in conventional forced-air cooling systems, ensuring uncompromised reliability in sealed outdoor enclosures and office environments.
Who and where it is for
Telecommunication access networks, wireless micro-base stations, outdoor integrated enclosures, utility substations, fiber-to-the-home/building (FTTx) central offices, and railway SCADA infrastructure.
Core advantages
- Natural convection cooling with zero fan failures, ensuring exceptional MTBF
- Ultra-wide input window of 85V to 300V AC with smart linear thermal and voltage derating
- High efficiency (>91%) and unity power factor (PF ≥ 0.99) reducing operational energy costs
- Native CAN bus integration with Smartpack and Compack digital supervisory controllers
