DISCRIPTION
The KHV series is an ultra-compact, medium-high voltage
DC/DC converters with 5sided metal shield case. Output
voltage can be adjusted by external voltage or external
variable resistor, with built in short circuit and over current
protection providing this unit with high reliability and long life.

Note
1.
The output voltage will be controlled by applying the Vcont voltage. Using an adjustable resistor or an external voltage, voltage should be applied
on the Vcont in in order to control the output voltage. When Vcont voltage=0V, the output voltage (output residual voltage) should be less than
2.0% of the max output voltage.
2.
The ON/OFF control is optional. When ordering, add a suffix “R” to the end of the product name. (example: KHV12-350S10PR; R=Remote
