DC 300V 50A Digital Voltmeter Ammeter DC VOLT AMP Tester Gauge With Red and Green Led No Shunt With

Technical Parameters: Supply voltage (non-isolated meter): DC3.5 ~ 30V (wide range), Note: The maximum input voltage can not exceed 30V, otherwise it will be burned Isolation meter (isolated power supply meter): DC8-18V Operating Current: <20mA Display: 0.39 LED, voltage - red, Current - Green Dimensions: 70 40 30 mm Installation hole: 68 38 mm Measurement rate: a500mS / times Accuracy: 1% (&pm; 1 word)
Extreme working conditions: Min. supply voltage: + 3.5V Max. supply voltage: + 30V Working temperature: -10 ~ + 65 Operating Humidity: 10 ~ 80% (non-condensing) Working pressure: 80 ~ 106kPa Sunlight: no direct exposure Power meter: Two line socket Thin - Black Line: Header supply Negative Thin - Red line: Header supply positive
(Note: voltage between red and black lines can't exceed 30V) Test side: Three line socket COM: Test Common V +: Test positive voltage input A +: Test positive current input; check the drawing before install or it will burn. Because the header by co-design, which means the earth wire of test and power supply is interlinked,so only can be connected to between the negative power supply and the negative of the tested device (We recommend to link the yellow line and the black lines together, to prevent outside interference caused by digital ammeter flashing) Package included: 1 x Digital Voltmeter Ammeter
