The "Model:DC PULSE" is a pulsed power supply that is effective in suppressing abnormal discharges that occur in reactive processes.
This power supply reverses the output voltage at a set period and cancels out charge accumulation (charge-up) on the target surface, thereby suppressing abnormal discharge and improving yield and throughput.

Features
- High power can be input by suppressing abnormal discharge.
- Reduces substrate damage caused by arcing
- Oscillation frequency can be set from 5kHz to 250kHz for output.
- Up to 6 units can be operated in parallel (only combinations of the same model)
- By changing the operating mode, it can also be used as a DC power supply with a low arc function.
