3½ Digital Red LED DC 0 to 50A Amp Panel Meter + Shunt 3½ Digital Red LED DC 0 to 50A Amp Panel Meter + Shunt - Requires a 5v Isolated Supply
This meter requires a COMPLETELY isolated power supply. A common A/C to D/C plug-in type adapter (wall wart transformer) will not work since they use an earth ground (The A/C neutral is grounded), not an isolated ground. Isolated transformers are special type power supplies specifically for electronic circuits of this nature. If you are not sure if you have an isolated transformer, then more than likely it is not and we recommend you use a battery instead of a transformer as the power supply. Please consider our volt/amp meter combination which of course does use an isolated power supply to power both meters.
Using a non-isolated power supply will fry the meter almost instantly!
