Heavy Duty Series

  • Designed for powering 12 and 24 VDC communication/navigation equipment aboard commercial vessels where reliability is the primary consideration.
  • Input voltage 115 or 230 VAC selected by slide switch on the front panel.
  • Excellent Regulation and Ripple Spec: Output voltage maintained within 1% under all line and load conditions within rating; Ripple is less than 40 mV P-P. (12 volt) or 70 mV P-P (24-volt)
  • Polyurethane conformal coated PC board and corrosion resistant heavy duty aluminum case with integral shock mounts assures survival in hostile environments
  • Heat generated by semi-conductors is extracted and dissipated by large heat sink fins that maximize air contact for cool operation and long life of components.
  • Supply and Load Circuit Protection: overvoltage, current limit; (set @ 105% of intermittent rating), thermal overload and input/output fusing.
  • Thermally activated cooling fan on ""CD"" units.

slightly smaller than sky high
Size: 30 FT, Style: 0 (1/0) AWG RED
wire is okay but it is definitely on the thinner side, was slightly smaller than my sky high 1/0 wire but for the price difference this is definitely worth it
