DC 0-100V 50A Current Voltage Digital Display Module

Features

Wiring:

Notice:

The voltage between the thin red and thin black lines must be within DC 4.5-30V
The ammeter can only be connected to the negative of the device under test and can only test amp in positive direction
Exceeds 5A, long-term full load working continuously, we recommended test side of leads directly soldered to the socket
When black thin line vacant, it is better to use insulating tape around exposed part of wire to prevent short circuits
If just used voltmeter, we recommended yellow line and black line connected together to prevent ammeter's digit flashing
