DC 1000A Shunt LED Digital Voltmeter Ammeter DC 0-100V 300V 600V Voltage Current Meter Dual Meter Ampere Voltage Tester Amp Gaug(White Cover,DC600V)

AmmetersAttention:1,999mA, 2A, 5A, 10A, 20A,the shunt is built in.2,More than 20A ,you must use a shunt to work,even 0.1A, or it will be burnt.3,More than 20A,the shunt is not built in4,Because the 24V battery charge full of floating voltage may be more than 30V, so "no" recommended direct use 24V battery.Features:The wide power supply range, with reverse polarity protection. Display voltage and current on the screen at the same time.Connection Method:This meter is equipped with five wires,Meter power supply: two-wire terminalsBlack wire: Negative power supply.Red wire: Positive power supply. Testing side: three-wire terminalsCOM: Test common terminal(The COM is commond negative of voltmeter and ammeter)V +: Test positive voltage inputA +: Test positive current input. It can only be connect the load negative and load power negative, as shown below.Suitable for "more than 20A ,must need a shunt:
