I have for sale a Gamma Research HPS1-a power supply. This is a unique supply that is optimized for providing reliable power to a 100W class transceiver such as a K2 or K3 in the smallest and lightest possible package. It is thus ideal for portable operation, DXpeditions, etc. The supply architecture combines a traditional switching converter with a large ultra-cap to provide additional power capability for operating modes with less than 100% duty cycle. With my K3, this supply provides capability for output powers of 30-35W RTTY, 75W CW and 100W SSB. The unit is in mint condition and works perfectly. I'm selling it because I've curtailed my portable operation.
The power supply weighs only 1.25 pounds! and is 3.4 by 1.6 by 5.2 inches in size. Output voltage is 13.8 Vdc nominal. Rated at 5A continuous and 22A at 25% duty cycle. For complete specs see: www.gammaresearch.net
Your purchase includes the Gamma Research instruction sheet, an adapter to convert the Molex output connector to a standard PowerPole and insured USPS Priority Mail shipping to your USA address. Price is $155 via PayPal.
