DISCONTINUED PRO AUDIO Kx33 - Low RFI 14V 4A DC power supply

This is a compact, low noise 115 / 230V  AC supply that is ready wired to connect directly to your KX2 or KX3 transceiver. It will deliver up to 4 Amps and easily power the KX3 up to its 15W power limit.

The KX-33 is also suitable for a variety of portable transceivers when purchased with the special adaptor cables. There is a cable now for the NEW Discovery TX-500 too!

Optional plug adaptor cables are available for the Xiegu X-6100, Discovery TX-500, Flex-1500, Yaesu FT-817, Yaesu FT-818,Ten-Tec 506 Rebel and others

The PAE-Kx33 is the first compact, lightweight AC-line operated switching power supply specifically designed to perform at the level required by the Elecraft KX3. When operating portable or traveling it is necessary to have a small, light power supply to either operate the rig or charge the batteries.

Since the KX3 receiver has world-class sensitivity, the supply must be RF quiet in order to power the rig while it is being used. Linear supplies can be very RF quiet, however dragging around a mains-powered 56 watt linear supply capable of a true 4 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 KX3 owners 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 HF rig owner
