0.28'' Digital Voltmeter Ammeter DC 100V 50A Voltage Current Shunt Volt Amp Meter Tester 3 Bits Dual LED Display Pan

brand new and high quality. Description: ● High precision and high reliability for high-end applications. ● It has reverse connection for protection and will not burn.

Specifications: Measure voltage: DC 0 ~ 100V Measure current: 0-50A Operating voltage: DC 4 ~ 30V Voltage error: ±0.1% Current error: ±1% External shunt specification: 75 mΩ Operating current: <20mA Refresh rate: about 300mS / times Display: three 0.28" LED digital tube Display color: A(red+red), B(red+blue) Lead Length: 15cm Dimensions: 48 x 29 x 22 mm, length X width X thickness Opening Size: 46 x 27 mm Net weight: 20g Working Temperature: -10°C~65°C

Wiring: Black line (thin): vacant or for buck circuit (module) negative Red line (thin): positive pole of power supply Black line (thick): COM, common measuring terminal Red line (thick): PW+, input terminal of measuring positive voltage Yellow line (thick): IN+, the positive of current input (Please refer to the wiring diagrams for more details)

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

Package includes: 1x Digital Volt/Ampere Meter 1x Current Shunt
