BOMB IIIH Series of Unipolar Pulse Bias Power Supply

BOMB IIIH Series of Unipolar Pulse Bias Power Supply


Technical Specification of Unipolar Pulse Bias Power Supply, BOMB IIIS Series

BOMB IIIS series of bias power supply works in two-stage high frequency conversion mode, with unipolar pulse mode on the output. The power supply voltage can be adjusted by changing the power supply voltage of high frequency conversion circuit; the voltage regulating circuit has 1% stability. High frequency conversion circuit can generate adjustable pulse voltage, width ranging from 10-90%. Because the output voltage and pulse width of the power supply adopt independent adjustment, the workpiece temperature rise is controlled by changing the pulse width, in the same time to meet the required technological voltage. The power supply is applicable to film coating of various tools and decorative coating.
