Kx33 Low-RFI 14 V - 4 A Power Supply by Pro Audio Engineering

Description

* WE WILL BE CLOSED FROM AUGUST 9TH UNTIL AUGUST 16TH, ALL ORDERS WILL BE SHIPPED AT THAT TIME, AND THANK YOU FOR YOUR PATIENCE*
Rigs such as the venerable Yaesu FT-817 and Elecraft™ KX3 HF Transceiver have raised the bar for portable HF performance, being able to fit a no-compromise station into a small shoulder bag is incredible! One necessary aspect of portable operation which has been elusive until now is a quality light-weight AC power supply. The PAE-Kx33 is the first compact, lightweight AC-line operated switching power supply specifically designed to perform at the level required by theese great HF rigs. When operating portable or traveling it is necessary to have a small, light power supply to either operate the rig or charge the batteries.  Linear supplies can be very RF quiet, however dragging around a mains-powered 56 watt linear supply capable of a true 4A 14VDC output is a problem, they are too big and heavy for truly portable use. Check out the size, weight and cost of just the 60Hz 56VA transformer some time! Like many hams we had been trying various small switching supplies not intended for communications use, and while they can be very small and light, they usually cause RF interference. As a result we often just used the supply to charge the internal batteries and unplugged it to operate, and with the internal NiMH battery pack voltage this limits output power to 5 watts.
The PAE-Kx33 was designed specifically to address all of these specific concerns of the portable rig owner, and features:
Innovative switching topology to minimize RF interference and optimize efficiency.
Extensive input and output filtering to ensure absolute minimum conducted and radiated RF.
Less than a pound weight including AC cord to maximize portability.
DC output is nominally 14V (see Specifications) at up to 4A.
Correct right-angle DC power plug as specified by Elecraft™.
Supplied with standard US AC cordset (see Specifications for details).
Lower noise and more output current capacity = better value than both competing and more expensive supplies.
In addition to 100% testing at the factory, every unit is tested for no and full load voltage and RF spectral output before shipping to you.
