Description: VA75010s is a multi-function meter which can display various physical parameters such as voltage, current, power, capacity, energy and working time in real time. Overvoltage, undervoltage and overvoltage can be implemented via a reserved relay interface. Over-temperature protection. Moreover, the meter uses 1.8 inches liquid crystal color as the display, and the display data is more comprehensive, clear, and easy to observe. This instrument is ideal for applications that require output voltage and current monitoring, as well as battery charging and discharging. Features: real-time display of voltage, current, power, capacity, energy, working time and other physical parameters, through the reserved relay interface can achieve overvoltage, undervoltage, overcurrent, over temperature protection. Using a 1.8-inch color LCD display as the display, the display data is more comprehensive, clear, and easy to observe. Ideal for applications that require output voltage and current monitoring, as well as battery charging and discharging. Main Features: Bi-directional current detection, for users who detect charging and discharging, they can easily detect bi-directional current without changing the wiring direction. The power-off memory function can memorize the number of AH and WH before powering off after power off, which is convenient for observation and measurement. The time and AH clearing function does not affect the next measurement. The AH number can be filled in without affecting the direct discharge measurement. Voltage, current, AH charging capacity, WH number, time and power are displayed at the same time, and the display information is comprehensive and clear. With the output function switch-off button, the output can be switched on or off flexibly. With overvoltage, overcurrent, over-temperature and other protection functions. It can be calibrated online to correct errors over time. The LCD display can be turned off when necessary to reduce the power consumption of the product.
