WSPRlite Power Conditioner Kit

Ideal for running your WSPRlite from a battery supply or "wall-wart", the WSPRlite Power Conditioner converts any 7 - 20 Volt DC supply into a super-clean quiet 5 Volt USB supply - perfect for your WSPRlite.

We use a linear regulator to avoid the noise problems so often associated with cheap switching regulators. Rated at 200 mA and with a re-settable fuse, the Power Conditioner will keep your WSPRlite happy - and safe too. The DC input is protected against voltage spikes by a special TVS diode and is provided with additional smoothing with a low-esr input capacitor. These features have been added in case you wish to use your WSPRlite in a mobile setting. Unlike simple chargers, we also condition the data lines to avoid unwanted noise affecting your WSPRlite.

The kit is supplied with a PowerPole for the DC input and a standard USB output. It's ideal for running your WSPRlite at home or in the field! The PCB has M3 mounting holes (mounting hardware not supplied with board kit).

The Power Conditioner is available in three forms:

  • The PCB kit consists of: 1 x PCB and all board components (no mounting hardware).
  • The PCB + enclosure kit adds an ABS box, laser-cut front panel and board mounting hardware.
  • Alternatively you can buy the Power Conditioner ready-built and tested.

Does not include mating connectors so don't forget to order a bargain pack of connectors! 

NOTE: this unit is not suitable for charging mobile phone or other devices.

    Nice build but don't use for another QRP TX because it will run very quickly very hot. To pity I couldn't use it for my Zachtek transmitter running only 300mW [Admin: the unit is designed to run a WSPRlite and is rated at 200mA maximum (see spec.). The Zachtek transmitter is less efficient than a WSPRlite and draws more than 200mA.]

    Haven't built the kit yet but looks good quality and very reasonable priced. Downloadable assembly instructions clear and very detailed

    Simple and it works

    Posted by Kirk Binning on 28th Apr 2017

    Purchased this as a kit and had fun building it. Easy to build and it works well. Put my power supply on the inlet, cranked the voltage up and down, and the outlet stayed rock steady at 5V.
