0.28 inch DC 100V 10A LED Digital Ammeter-Voltmeter

This is 0.28 inch DC 100V 10A LED Dig­i­tal Ammeter–Voltmeter. This meter will mea­sure up to 100 VDC with a 0.1‑volt res­o­lu­tion.One thing to note is, this meter has 2 wiring har­ness­es. One har­ness is to pro­vide pow­er for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the mag­ni­tudes of volt­age, and cur­rent are dis­played on the same screen at the same time.This can be sup­plied any­where from 6 volts DC up to 30 VDC. This is a sep­a­rate pow­er sup­ply that is iso­lat­ed from the source, it is pos­si­ble to use the same sup­ply but it seems to affect the amp meter read­ing. The 3 wire har­ness is used for a ground that con­nects direct­ly to the bat­tery or sup­ply ground of the load.Wiring Instructions:Note: There are two dif­fer­ent wiring vari­ants (i.e. yel­low wire and Green wire ) with the same work­ing func­tion­al­i­ty is avail­able which will be shipped ran­dom­ly. Use the fol­low­ings guide­lines accord­ing to your ver­sion.CASE 1: Onboard Wiring Instructions for “Yellow” Wire connection1. Thin Red Wire (VCC): pos­i­tive pole of pow­er sup­ply input (4.5–30V) (Note: if the mea­sur­ing sig­nal is less than 30V and the pow­er is ade­quate, can be the pow­er sup­ply of mod­ule)2. Thin Black Wire (GND): the neg­a­tive pole of pow­er sup­ply input (4.5–30V, com­mon ground with mea­sur­ing sig­nal)3. Green Wire (VIN): pos­i­tive pole of mea­sur­ing sig­nal input (0–100V)4. Thick Red Wire (I ): pos­i­tive pole of cur­rent input (series con­nect on the pow­er sup­ply cath­ode)5. Thick Black Wire (I-): the neg­a­tive pole of cur­rent input (series con­nect on the pow­er sup­ply cath­ode)Connection Diagram:Note: If the input volt­age is more than 5V then please use the buck con­vert­er.Features :It mea­sures up to 100V and 10A DC.Very handy and small in size.It requires a pow­er sup­ply of 5V.100% Brand new and high qual­i­ty.
