UDI-100/200/540 DC Inverter Power Supply

Real time monitoring of the welding process can be realized through the built-in waveform display function.<Application field>

Motor terminals, motor leads, commutator hooks, relay and motors, etc.

Features

■The controller and welding machine are integrated for convenient operation.

■The built-in waveform display function allows you to monitor the welding process in real time.

■Configures I/O expansion terminals used for communication with the transformer, and displays transformer operation information.

■It has a built-in monitoring function for important welding parameters such as time, current and voltage, and in combination with RS-485 communication, realizes production control and data traceability.

■Built in 7 kinds of transformer frequency, and can be easily switched.
