Product Description

DESCRIPTION:

• This is 0.28 inch digital voltmeter DC 100V 50A ammeter LED ammeter with shunt. This meter will measure up to 100 V DC with a resolution of 0.1 volts.
• One thing to note is that this meter has 2 wiring harnesses. One of the harnesses is to power the meters, that is to say the 2 poles with a RED wire and a BLACK wire. Small in size, portable, voltage and current magnitudes are displayed on the same screen at the same time.

Note:

• There are two different wiring variations (i.e. yellow wire and green wire) with the same working functionality, which will be shipped randomly. Use the following guidelines depending on your version.

CASE 1: Integrated wiring instructions for connecting a “yellow” wire

1. Thin red wire (VDC): positive pole of the power input (4.5-30V)

(Note: if the measurement signal is less than 30V and the power is adequate, this may be the module power supply)

2. Fine black wire (GND): negative pole of the power supply input (4.5-30 V, common ground with measurement signal)

3. Green wire (VIN): positive pole of the measurement signal input (0-100V)

4. Thick red wire (I +): positive pole of the current input (series connection on the supply cathode)

5. Thick black wire (I-): negative pole of the current input (series connection on the supply cathode)
