There are three types of chopper modules, each one for particular power source:

1. OrigoMig 4002c/4002cw
2. OrigoMig 5002c/5002cw
3. OrigoMig 6502c/6502cw

Differences lay within heatsinks dimensions, type and number of power IGBT modules,
capacitance of capacitors, type of rectifier diodes. All of types have similar structure.
