UMHVP no backround.jpg


The UMHVP Series is a family of low cost ultra-miniature single-output DC to DC converters supplying up to 5kV in 0.125 cubic inches (0.5” x 0.5” x 0.5”). These ultra-compact converters are ideal for applications requiring small size and ease of use.


HVM’s proprietary resonant converter design minimizes quiescent current and operating noise while delivering maximum performance and reliability. A special feature of this power supply is its extremely low input current at no load, making it ideal for battery powered applications.


The output voltage is directly proportional to the input voltage from approximately 0.7V input to maximum input voltage, allowing for a controllable output voltage and features excellent linearity.


The output power rating is 0.5W and the input to output isolation is ± 500V.


The UMHVP Series is very stable over a wide operating temperature range.
