The SK Series is a family of miniature single-output, fully regulated DC to DC converters supplying up to 5kV @1W in 0.9625 cubic inches (1.75”L x 1.10”W x 0.50”H). These ultra-compact converters are ideal for applications requiring small size and ease of use. A high impedance programming input makes it very easy to use, eliminating the need for a low impedance adjustable power source voltage.
HVM’s proprietary, ultra-compact resonant converter design minimizes quiescent current and operating noise while delivering maximum performance and reliability. The SK Series is sold with a factory installed copper adhesive shield for further noise reduction.
The devices operate directly from 5VDC ± 0.5VDC input. Output voltage is independent of input power voltage and is proportional to the programming voltage (0 to 5V produces 0 to full scale output) and features excellent linearity. Adjustment pads are available to calibrate the unit to ±5% outside of factory settings. The output power rating is 1W. The SK Series is very stable over a wide operating temperature range.
The SK Series is available with alternate output voltages. Consult sales for additional information

The SK Series is the newest member of our mini high voltage dc to dc converter family. It is easy to use and requires no external components, which saves space. It offers outstanding load and line regulation, with its low quiescent current and factory installed copper adhesive shield, we have made doubly sure that operating noise is reduced to a minimum. This is why it is so widely used in a variety of industries that includes: the military, scientific, aerospace, analytical, and bio-medical fields.
This compact but powerful dc to dc converter has low output ripple and EMI/RFI, and can operate throughout a wide range of temperatures. It also comes in a miniature PCB mountable package. It is delivered to our clients at a low cost. Because our clients have certain specifications, the SK Series can be made available with alternate output voltages.
Our goal has always been the same from the moment we started in 2004. Create, manufacture and deliver the most advanced and cutting-edge technology to our clients at the lowest possible price. This is how we empower our customers to create the technology of the future, and it is our honor to play a small role in that process.
