I am working on a vcd 8 with a problem of loosing the 5 volts supply. We have fitted a new supply that also provides the 15 volts. When we remove the connector on the power chassis for the 5 volts the power supply shows OK. When fitted the 5 volts is

Found the problem. Thanks for the pointers. I had set the voltage to 5.00 volts as it was reading 4.86 volts. I still had the problem. A slghtly burnt wire going into the spade connector on the back of fuse holder 12 (5 volts). The reason the voltage

4.85 V - 5.2 Volts. That is on the computer power inlet, Not the on the power supply. /Best Regards

There are pots on the board in the power supply to adjust the voltages after the machine is powered up. The location of these pots are in the munual supplied with the machine

Something on the 5v side is pulling it down. I would check every thing associated with the harness you are disconnecting. Your shorting somewhere! Don't have a schematic in front of me. Also look for leads getting into the backside of your connecto

Resistor Help Needed

Three LEDs, 3.5volts @.02amps each is 10.5volts. You said you calculated out an 82 ohm resistor so 82 ohms * .02amps is 1.64volts, I guess your going to use a 12volt supply. P=I*E =.02amps * 1.64volts =.033watts so a .25watt resistor will be fine

How high a voltage are we talking , 240 volts, 4000 volts , 26000, volts 60,000 volts, 240 volts is easily done as we go up the scale insulation becomes a bigger problem and winding machines have to be much better in control of tension,also at higher

charging batterys via solar

What would happen if a 2 volt solar cell was hooked through a diode into to a 3.6 volt nicad (3xAA)? would it charge it at all? just a bit but never fully? would battery deliver 3.6 volt after charging? If left long enough would it charge fully?

If i hook a 5amp/12volt solar panel to a 6 volt lead acid battery, would it recharge it? is it as simple as hooking the two together? thanks,

Question on ANSI/ESD-S20.20-1999

1) I had downloaded ANSI/ESD-S20.20-1999 from www.eosesd.org web site. I am not clear whether section 6.2.3.2 is correct. It states that " All process essential insulators that have electrostatic fields that exceed 2000 volts should be kept at a mi
