Questions & Answers

  • What is PWR-IE170W-PC-DC used for?

    A 170 W industrial DC input power supply providing substantial capacity for PoE-capable IE switches or multiple devices in DC-powered cabinets and vehicles.

  • What input voltages are supported?

    Wide DC input ranges are typical (for example 12/24/48 VDC). Verify your exact model specs and ensure proper polarity and fusing per industrial codes.

  • PWR-IE170W-PC-DC vs PWR-IE170W-PC-AC—difference?

    The DC variant accepts cabinet DC rails; the AC model accepts mains. Choose based on available power sources in your enclosure or mobile platform.

  • Is redundancy possible with DC PSUs?

    Yes. Use diode OR-ing or dedicated redundancy controllers. Feed from separate DC rails/batteries when available to maximize uptime.

  • How to plan for temperature and derating?

    Consult derating curves for high ambient. Provide ventilation and spacing. In sealed enclosures, consider heat sinks or fans if loads approach maximum.

  • Can it support heavy PoE loads?

    It can power the switch’s internal PoE budget within overall capacity. Ensure total device plus PoE draw stays under 170 W with margin for peaks.

  • Any EMC/noise recommendations?

    Use proper grounding, shielded cables, and keep high-current DC paths away from sensitive IO. Add surge suppression where transients are common.

  • Installation advice?

    DIN-rail mount, ferruled wires, correct polarity, and labeled terminals. Verify output voltage before attaching critical loads.

  • Monitoring options?

    Use LEDs/status contacts for local alarms. Periodically check output under load and log cabinet temperatures.

  • Maintenance tips?

    Inspect terminations, clean dust, verify voltage, and replace after years of high-duty service to avoid unexpected failures.
