Ultra small size adjustable output type high voltage power supply
2W to 2.6W high voltage DC-DC converter
0V-470V、1000V、1500V、2000V VHV Series
The VHV series is the first high voltage product supply in the industry to use the latest SMT (surface mount technology)
making the size 1/5 to 1/6 from the normal product, with an adjustable output voltage type mid-high voltage DC-DC converter.
Output voltage can be controled using an external voltage or external adjustable resistor. The VHV series has adopted a 5 side
metallic shield, with farther low ripple and low noise.

■ Model name/Rating
■ Specifications
Note1: The output voltage can be controlled by impressing the Vcont voltage. Using an adjustable resistor or an external voltage,voltage should
be impressed on the Vcont pin in order to control the output voltage. When Vcont voltage=0V the output voltage(residual output voltage)
should be less than 0.5% of the max output voltage (at Input/Output rating).
