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.

Great product but screws are annoying
Size: 6 pairs
These 24K gold-plated banana plugs are a solid choice if you’re looking for an easy and reliable way to connect your speaker wire. The connectors feel sturdy, and the gold plating gives them a clean, professional look while also helping prevent corrosion. Installation was straightforward — the wire slots fit snugly, and once tightened down, the connection feels secure. I used them for both my home theater and stereo setup, and the sound quality is clear with no noticeable interference or loss. The pack includes 6 pairs (12 plugs), which is plenty for most speaker setups, and they fit my receiver and speaker terminals perfectly. My only small complaint is that the screws could be a bit tighter or smoother when clamping the wire — you just need to make sure they’re seated properly to get the best hold. Still, once installed, they stay firmly in place.

Works great with all speaker wires
Size: 6 pairs
It works pretty well with standard and thin speaker wires. It makes so much easier to plug and unplug speaker wires. Color coded makes it easier for future. Banana plugs are worth. Double screws ensure wires remain securely attached. Screws are bit too tiny and had to run to the store to get one of those fine tip screw driver though.
