do i need to disconect the shunt if use is less then 10A?

It will read 10 amps with out a external shunt. If the external shunt develops a voltage drop of 75 millivolts @ 100 amps. The resistance of the shunt = .0007 ohms. The ammeter internal shunt @ 10 amps would have a voltage drop of 7.5 millivolts. The power dissipation would only need to be 75 milliwatts. Easily done with surface mount components.

Hi, the output is limited to whatever the input power is. Example: 12 volts @ 20 amps is 240watts total available power. If you convert it to 24 volts, you only have 10 amp outpue minus whatever the conversion draws. You can't get power out of things air. Make sure to use additional heatsinks as these are rated 150 watts max. Good luck!!

Yes, it draws 15 MA when connected. It is not necessary to disconnect unless you have a small battery.Best Regards,EH

10 amps should be ok but I would use a relay just to be safe. It would also save on the life of the relays in the remote and you will be worry free for years.

It shouldn't need to. We just replaced it for the fan switch. It has feed and feed through.

Solder it to your main positive and negative nodes on your motherboard. make sure the amperage and wattage are useable.

Checking amperage has safety implications, and I suspect that's why low-cost units are limited to 20A. You can get more information from the following video: http://m.youtube.com/watch?v=ar7qkMHKw4

Most likely. Depends on how much current these devices draw, but I'm guessing all those added up are well below 10A.

You should not use more than 80% of the rated capacity which would be 16 total amps continuous. I am not an electrician.

Yes, as Jason said below. Just remember to shut off all four of the valves before disconnecting.

It depends a lot on the application and duty cycle. If you're running a continuous load, 4 A should be perfectly safe. If you are running intermittent loads, I would not exceed 20 A, and only for short periods of time (feel the leads to see how quickly they warm up under higher loads). These are meant for testing and prototyping, so odds are you probably aren't walking away from the area... but if you are away from the area that these are being used, it's best to make sure the loads do not exceed 4 A continuous.

Check the capacity of the circuit you have it plugged into. This needs to be on a 20A circuit as it will draw up to 17A, depending on your power supply. That is, BY ITSELF on a 20A circuit.The MINIMUM current draw will be 15A and that is already too much for a 15A circuit, you will likely blow the circuit. If it doesn't blow the circuit as soon as you plug it into a 15A circuit (and turn it on), there is something wrong with your wiring.

Yes a shunt is necessary to allow the meter to work. I believe it is 500 mA.

YES-The red wire is connected to a battery sourse. The shunt is connected in ground wire between battery and device. Google the part number YB27VA located on back of meter for complete wiring diagram

There is one red and black wire that needs to be connected to a separate power source. I used a 9v battery. Black goes to the side of she shunt inline closest to the battery, the yellow goes to the shunt closest to load. The Red goes to battery positive. I used the meter to measure amps from my inverter. Works great.

I dropped down from 12V to 7.5V without a heat sink. Not sure about a bigger drop.

No,NO more than 10 amps or you will start to overload, things get hot,could start to melt and cause fire if not fused properly.
