    increasing backup time of ups

    Perhaps you have to reinforce the charger circuit to cope with the larger capacity battery too! Do you have access to a schematic diagram for your UPS?

    Auto dimming problem

    Hi AG, This is all in the wrong board because as soon as you divert from the original circuit it’s not a “Projects Q&A” anymore! See this: http://www.electronics-lab.com/forum/index.php?topic=5433.0 mp, The use of a regulator disqualifies the project from this board doesn’t it? Hope...

    Auto dimming problem

    MP, What rating for the pots do you recommend for R3 and R4 to be able to set them at zero ohms in the car battery circuit when S1 is closed?

    Auto dimming problem

    That’s a really badly engineered circuit!  :o And why it’s published is a very good question!

    NAD schematics urgently needed

    Datasheets which can be downloaded from manufacturers websites may of curse be ditributed! But, a service manual which sells for money is not allowed to be copied and distributed!

    Can I shorten the SLA battery charging cycle?

    Hi hunt, It’s never a good idea to drain the batterys completely, this should always be avoided. Even down to 20% is somewhat low in my book, I prefer 40% minimum for a long healthy life of the batterys. If they are discharged completely (by accident) it’s very important to get them fully...

    Triggering a pump through a DC pulse generator

    Hi Edge, You like to increase the amplitude of the pulses form 5mV to 24V to interface with a PLC, right?

    Problems with three wheel Driving Mechanism

    Why not put one motor on each back wheel and let the front wheel swivel? This way it’s very simple to steer the thing!

    Slow power up effect

    We don’t know the data for your meter but what would happen if you increase the value of the capacitor even more?

    NAD schematics urgently needed

    That’s right; why bother? Copyright is all the same if you post a copy of a magazine, an E-book or a service manual and this is because someone loses money for each copy not sold! This is not a question about altering or changing the copyrighted stuff but making copies of it. Otherwise it would...

    NEC monitor help!

    The 12V supply was fine, only the output from the inverters was missing.

    Slow power up effect

    Hi Daisy, If the resistor lowers the reading its value is too high. If the capacitor makes no difference its value is too low. It all depends on the internal resistance of the meter. If you use a cap without a resistor the cap will charge very fast on power up and discharge fast through the...

    110v supply

    Of curse, that would also work. These alternatives do not alter the VA rating as other solutions would, at least not noticeable.

    That didn’t exactly answer my questions.  :-\

    12V Fan controller

    Remember to check the maximum available current for the -5V tab! Also the motherboards current requirements at -5V. Often the current is just -0.5A and this might affect the motherboard even more than other solutions. A fan might use almost as much at startup and this might wipe out the...
