ITEM NAME:1.9" DC 30V 30A Voltmeter Ammeter Digital Red-Blue Dual LED Display Meter Description: Dual-display voltage and current meter,small size.Display voltage and current on the same screen at the same time. Current measured must be connected in series with the negative pole of the load,otherwise the IC will be burned out. Self-contained shunt, no need to connect external external flow. And with fine tuning,easy to test. Adopt high-current terminal block,large contact area of the movable block,and the connecting wire is firm and reliable. Widely used in battery charge and discharge control (inverter, UPS, backup power supply and various DC electric equipment), automotive battery control, electric vehicle power supply control, DC motor control,etc. Specification: Overall Size: 48x29x30mm/1.89x1.14x1.18inch Installation Size: 46x27mm/1.81x1.06inch Voltage Measurement Range: 4.5V-30V ( ±1%) Current Measurement Range: 0-20A/0-30A ( ±1%) Working Current: ï ¼Å“15mA Resolution: 0.01A (below 10A); 0.1A(over 10A) Shunt: Self-contained shunt (Low temperature bleaching manganese copper wire) Display Mode: Double Three-digit 0.25" LED digital tube Display Color: Red+Red, Red+Blue Overvoltage Protection,Undervoltage Protection Refresh Rate: ≠¥500ms/times Working Temperature: -10~65℃ Working Humidity: 10~80% RH Working Pressure: 80~106kPa Package Includes: 1 Piece LCD Digital Voltage Ammeter Note: Color maybe slightly different due to different monitor.
