DC 90V 500A Digital Voltmeter Ammeter Voltage Current KWh Watt Meter 12V 24V 48V 72V Battery Capacity Power Monitoring

This volt-ampere meter is a new type of volt-ampere meter that can measure various physical quantities such as voltage, current, charge and discharge capacity, time, power, etc.The instrument uses color LCD to display the measured data, and the display information is comprehensive and user-friendly. This meter uses a Hall sensor to detect current, which is convenient and simple, and is very suitable for applications that need to monitor the output voltage and current, and charge and discharge the battery. Current measurement range: 0-500A Display resolution: 0.2A Voltage measurement range: self power supply (12-90) V external power supply (0-90) V Current accuracy: +/- 3% +/- 5 words Voltage accuracy: +/- 2% +/- 5 words Voltage: 0.01V Capacity: 0.01AH Time: 0.01H (1min) Measurement rate: 5 times/sec OVP (over voltage protection): 0.01V-90V OPP (over power protection): 0.01W-9.99KW LOP (undervoltage protection): 0.01V-90V OCP (Over Current Protection): 0.1-100A OAH (overcharge protection): 0.01AH-9999AH OFT (overtime protection): 1min-99hour59min colour: black Material: plastic size: 7.9x4.3x5.2cm Package Contents: 1 x Voltage and current meter

• Voltage, current, charging capacity AH number, WH number, time, power are displayed at the same time, the display information is comprehensive and clear.
• Power- memory function, after power-, the AH number before power- can be memorized, which is convenient for observation and measurement.
• The current is detected by the Hall sensor, and the wire that the current passes through can be passed through the round hole of the sensor. The current can be detected in both positive and negative directions, safe and convenient.
• Two-way detection of current, users who detect charge and discharge can automatically identify and detect two-way current without changing the wiring direction.
• The time and AH number reset function does not affect measurement. The AH number can be filled up without affecting direct discharge measurement. It has protection functions such as overvoltage, overcurrent, overpower, time limit and overcharge.
