UP FOR SALE HERE IN MY STORE ARE 1-5PCS OF A 3.5 DIGIT LCD VOLTMETER THAT GOES UP TO 1999 DEPENDING ON THE SERIES RESISTER USED & WHERE THE D.P. IS SET FOR. AS THIS DESIGN IS BUILT AROUND THE INDUSTRY STANDARD ICL7106A ADC IC MODIFYING IT IS AS EZ AS LOOKING AT THE APPLICATIONS NOTE AS IT IS BUILT TO THAT SCHEMATIC. THE UNIT RUNS ALMOST FOREVER ON A GOOD QUALITY 9V BATTERY BUT ONE CAN ALSO USE A BATTERY PACK OR POWER PACK. WE WERE USING THEM AS THE VOLTAGE OUT METER ON OUR NEWEST BUCK BOOST CONVERTER WE MNF'D FOR ANOTHER COMPANY. IT MONITORED THE +10VDC & -5VDC THAT CAME OUT OF OUR CONVERTER THAT WAS DESIGNED AROUND A LTC3780 BUCK BOOST PWM CHIP. THIS WAS NEEDED BECAUSE THE USER WOULD FORGET TO PAY ATTENTION TO THE BATTERIES VOLTAGE & PRETTY SOON THE UNDERVOLTAGE LOCKOUT KICKED IN & SOMEONE WOULD HAVE TO TURN THE CAR OVER TO CHARGE UP THE BATTERY THUS TAKING THIER HAM GEAR OF THE AIR TILL THE BATTERY WAS CHARGED UP HIGH ENOUGH WHICH IN OUR CASE WAS 8VDC. THESE MODULE CAN HAVE THIER SPEC'S CHANGED BY THE ADDITION OF A RESISTER & OR A JUMPER SO AS TO CHANGE MAX VOLTAGE AND WHERE THE DECIMAL POINT WOULD BE. THIS ALL CAN BE FOUND IN THE MNF'S DATASHEET! OUTPUT. THANKS FOR LOOKING AND GOOD LUCK! Please look at my other items for sale! (all content is the responsibility of the poster) |
