[Elecraft] Low power version of solar controller

[Don Brown]

Hi

I have a quantity of circuit boards for a early version of my solar 
controller. This controller uses the same chip and design as the controller 
I currently sell except it will only handle 1.5 amps and does not have the 
circuit to turn off the charge indicator LED when the solar panel is 
supplying less than 11.5 volts. This controller can handle solar panels up 
to about 25 watts and would be ideal for use with one or two Volkswagen 
panels or one of the small 5-10 watt trickle charge panels sold by Harbor 
Freight or Northern Tool. This would be plenty of power to charge a 2-10 amp 
hour SLA battery for use on a QRP K2, K1 or KX1. With a 35 amp hour gel cell 
battery and a 15-25 watt panel you could run a K2/100 several hours per day 
with no other source of power.

The controller kit includes a fiberglass silk screened and solder masked 
circuit board and all parts on the board, assembly instructions and 
schematic. There is a terminal block for easy connection to your panel and 
battery. The circuit does not generate any RF noise and uses a precision 
voltage regulator IC and a 45 amp power FET to control the charging current.

I am selling these kits for $16 including postage con US while quantity 
lasts. When these are gone I will not make any more of this version although 
the 200 watt version I will continue to supply at $30

Check or money order only. Sorry no credit cards or PayPal
