    Tips: How to install the voltage sensor?

    There are 3 installation methods of voltage sensor:

    1. Pin-welding installation of the circuit board: Make lines on the circuit board, and weld the voltage sensor to the circuit board like a component. Its advantages are small size, light weight, space saving and easy installation.
    2. Screw fixation installation: The voltage sensor is screwed to the bottom of the chassis or a fixed position, and the external connection is through a variety of different terminals. The advantages are very firm and easy to disassemble.
    3. DIN rail installation: There is a standard 35mm wide dovetail groove on the bottom of the voltage sensor, which can be installed at DIN rail. Its advantages are convenient, versatile, and suitable for field work installation.
