Product Introduction:

ZX7-IV is a MMA control board, which applies to single-tube IGBT full-bridge welding machine. It is divided into power supply board with switch and power supply board without switch. The board is small-size, low-cost and easy to use with high integration and few peripheral connections.

Characteristics:

1. The IGBT driving frequency of the two kinds of boards is 20K, and it has functions of pulse by pulse current limit, peak current detection, and constant peak current, with sampling resistance not required.

2. Power supply board without switch: the control transformer can be used to supply AC voltage and 220V or 380V MMA power can be supplied as support.

3. Power supply board with switch: the control transformer is not required, and the switching power is directly supplied by the bus; the DC voltage input range is 200V-600V, and 220V or 380V MMA power can be supplied as support. The board has 24V 0.5A DC fan power and 5V data display instrument power.
