Description: Ac9010h voltage meter is a type of new physical current voltage that can measure voltage, current, charge and discharge capacity, for time and energy, etc. Meanwhile, it can also set the parameter to achieve overvoltage for protection, over loading capacity, and limit for protection, etc. Vac9010h use the non-contact detection of the hall to check the current, which can safely detect the current and use it convenient. Measured data and instrument used color lcd to display. The information will be comprehensive and humane. The meter is very suitable for monitoring the output voltage and current, as well as battery charging and discharging and other applications. Features: brand new and high quality For the user to charge and discharge can be automatic identification and bidirectional current direction, no need to change the direction of the wiring. Aafter turning off the memory function, turning off the ah number, it is convenient for people to observe and measure. AH number and current reset function, do not affect the next measurement. Voltage, current, charging capacity ah, wh, for time, energy will show at the same for time, too, shou all information clearly. With the output and off function, flexible cab to open or disconnect the output (relay need). With over voltage, over current, over power, litmited for time, load for protection function, etc. Can calibrate online, give a convenience for the customer to correct the error in for time. LCD panel can be manually put out or less than 300m automatically screen out in one minute. By detecting the current sensor of the hall, the current through the round hole of the thr wire through the thr sensor, both the current of the side direction can be detected. It is safe and convenient for users. Applicable scope: charge monitoring and discharge of electric vehicle battery, photovoltaic electricity monitoring system and so on, the first current empty charge charging needs to clean.
