LED digital ammeter,Electrical instrument DC0-50A ammeter,Mini ameter blue color

1, Measuring range of this ammeter is  DC0-50A.

2, The ammeter must match 50A/75mV shunt to be used, but the price does not include shunts.

3, You must use an external power supply, the power supply voltage DC4.5-28V.

4 Special Note: In order to be able to take power measurement circuit ammeter work performed, the meter is designed to power and the input common ground that the sampling line (thick) black wire is the ground wire, and the other thick pick a meter of the amplification circuit input. Therefore, the sampling line (thick line) and shunt connected with it is totally unacceptable positive, must be connected to the electrical appliances after (ie, the negative electrical appliances). Otherwise, it will instantly burn ammeter, causing no display or display ---. Please confirm before buy, the two meter thick and they are connected with the shunt must be connected between the two negative! Please refer to the specific connection wiring diagram on the page. Our prominent position has been explained on the page.

5 Meter high input impedance, high requirements for power supply ripple and susceptible to interference. Please do not use bad power converter (especially DC / DC switching power supply). Do not put ammeter and shunt near interference sources (such as electric car chargers), and the ammeter shunt between the lead is not too long, if you must be long, then please use shielded cable.

6, The meter is not suitable for use in electric vehicles. 1, the electric car for outdoor use, easy to damp meter water cause damage; 2 meter connection between the shunt, the signal is very weak, the largest only a few dozen millivolts. Such a small signal, are particularly vulnerable to interference. Coupled with the electric car, this connection will be very long, fading and interference will seriously affect the ammeter work. It is not recommended to be used in electric vehicles ammeter.
