DC 400V 300A LCD Voltage Current Watt Power capacity tester Digital Combo Meter coulometer module for 12V 24V 48V Car Solar | Электроника

VAT Series A can measure the DC voltage, current, power, charge and discharge capacity, watt hour, time, temperature color coulomb meter；Meter is divided into measurement module and display module, the two modules can use the USB cable to connect the signal transmission, but also through the built-in wireless RF circuit to transmit signals；Accessories include USB data cable and temperature sensor；Measurement module can identify the forward and reverse current in both directions, without changing the wiring can be achieved on the battery charge and discharge capacity monitoring；Very suitable for solar power, wind power, electric car battery use.

1、Bidirectional detection of current, convenient wiring；

2、Solve the problem of zero drift of the old product, the current can also ensure better accuracy after working for a long time;

3、Wireless mode, the farthest transmission distance can reach 10 meters, USB data cable using Andrews mobile phone data cable, the connection is solid, not easy to loose;

4、Display interface is divided into large font display interface, full-featured display interface and black and white display interface, to ensure that the sun can clearly see the display parameters;

5、Equipped with relays to achieve circuit over-current protection, over-voltage protection, under-voltage protection;

6、During the measurement, the ampere hours, watt hours and time can be cleared without affecting the next measurement.

7、The display can be set to extinguish the screen, press any key to wake up the screen;

8、Button touch buttons, feel comfortable, clean and elegant interface;

9、Wireless mode can set different communication address, multiple machines at the same time do not interfere with each other;
