3.3 Description of functions of voltage divider board
The voltage divider board is to reduce the voltage after arc starting of plasma cutting torch in a certain
proportion, and is separated and converted to the functional module reflecting the low-voltage signal of
cutting nozzle and cutting board. It is the indispensable accessory in the height monitoring and control
of plasma cutting. The voltage dividing ratio of the voltage divider board of standard configuration is 50:
1.
The description of various interfaces of the voltage divider board is shown in Figure 3-10.
