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  
reducedby 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.  
■ Features  
･Ultralow ripple noise 10mVp-p  
･World's smallest size (about a 60%  
reduction from comparable  
conventional models)  
･ON/OFF Control  
･Adjustable voltage by variable resistor or  
external voltage  
･Adjustable output voltage from 0 to  
100%  
･Use of pentahedron metal shield case  
･PCB mount type  
･Control voltage 0 to +6V  
･Built-in over current protection circuit ･High reliability and long life  
･Output capacity 1.5W  
･Supports 24V input with an external DC-DC converter

■ Specifications  
Line regulation  
0.01% typ. (for a line regulation of 11.0 to 13.0V)  
Load regulation  
0.02% typ. (for a load current regulation of 0 to 100%)  
Temperature regulation  
Over current protection  
Output voltage setting accuracy  
70ppm/°C typ. (for temperature regulation of -10°C to +50°C)  
Drooping characteristic, built-in automatic return circuit, activated at 105% or more  
±2% or less (when controlling a 6.0V external voltage)  
Output voltage control  
ON/OFF control  
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  
Operating temp range  
Storage temp range  
Operating humidity range  
20% to 95% RH (no condensation)  
Isolation between input and  
output  
Non-isolated type (2pin through 6pin are connected inside)  
MTBF expectation  
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.
