Ultracompact, Adjustable Output High-Voltage Power Supply
1.5Watt Medium-High Voltage DC-DC Converter
Volgen
1000V, 1500V, 2000V VHV Series
The VHV series is our new line of medium-high voltage DC-DC converters featuring an ultracompact size with the footprint
reduced by about 60% as compared to conventional models.
With a pentahedron metal shield case, ripple noise has been reduced to as low as 10mVp-p. Output voltage can be adjusted by
external voltage or external variable resistor. The built-in short circuit and overcurrent protection provide high reliability and a long
life.

MTBF expectation
Either with 0V to +6V external voltage or a 5KΩ external variable resistor
Between 2pin and 5pin, OFF when opened and ON when short-circuited
-10°C to +50°C (no temperature derating needed
-25°C to +85°C
20% to 95% RH (no condensation)
Non-isolated type (2pin through 6pin are connected inside)
Min. 390,000 to 400,000H (calculated from Bellnix MTBF calculation table)
Note 2 Output voltage is controlled by applying Vcont voltage. Apply voltage to the Vcont terminal by either variable resistor or external voltage to control output voltage.
Note 2 When Vcont voltage is zero, output voltage (output residual voltage) will be within 0.5% of maximum output voltage (input/output rating).
Note 3 Details are subject to change for improvement, etc., without prior notice.
