Multifunctional Wireless Voltage Current Meter Digital Bi-directional Voltage Current Power Meter Ammeter Voltmeter LCD Display

This meter can measure voltage, current, power, charging capacity and time, etc in both directions. LCD display, several parameters displayed on the screen at the same time, is convenient for readings. At the same time, it also has many functions, such as over-voltage protection, over-current protection, over-charge protection, etc.
Features:
Can measure varied physical quantities, such as voltage, current, power, charging capacity and time, etc.
Bi-directional measurement of the current, no need to change the wiring direction.
Wireless data transmission between the meter and expansion board, convenient for use.
With memory function if powered off, can memorize the last AH data.
Users can set parameters to achieve over-voltage protection, over-current protection, over power protection, overcharge protection, etc.
LCD display, several parameters displayed on the screen at the same time, easy to read.
Suitable for monitoring the output voltage and current, as well as the battery charge and discharge applications.
Small size, light weight, convenient to carry.
Note:
The meter should be powered by 5-24V power supply whether self-powered or powered by external power supply.
