7. VANJING DC 0-100V 300A DC Multifunctional Wireless Bi-directional Voltage Current Power Meter Ammeter Capacity Time Meter with Color LCD Display (DC 0-100V 300A)
Feature
Two Modules and Radio Installation Instruction:The instrument is divided into two modules,the display module and measurement module, which it not only transmits signals by connecting usb cable but also through the built-in wireless RF circuit to achieve the signal transmission. The measurement module can identify the forward and reverse current. There is a radio installation instruction in our listing,if you have no idel how to use the voltmeter,please see the voltmeter carefully.Large font display interface: The main parameters are displayed in the large LCD display such as voltage current power time watt hour temperature etc. The parameters can be showed clearly in any condition due to the large font display interface. The display can be closed and woken up by pressing any button.
Wireless model: The voltmeter can operate the wireless model within 10 meters, under wireless model, it can be set different communication address, so many machines can work at the same time without any interference.
Touch screen and protection function: The button is touch screen design, so it is easier to press buttons, and the voltmeter is built-in relay, which can achieve over-current protection, over-voltage protection, under-voltage protection in the circuits.
Package information: display module x1, measurement module x1, USB data cable x1, temperature sensor x1, manual x1. Please pay attention to the relay, there is no relay in the 300A voltmeter, if you want to use relay, you need to buy the relay by yourself. If you have any technical issues, please contact us by e-mail.
