The nHV Series is a family of micro sized single-output DC to DC converters supplying up to 1kV in a (.45”L X .35”W X .37”H) case size. These ultra-compact converters are ideal for applications requiring small size, high performance, 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 resonant converter design minimizes quiescent current and operating noise while delivering maximum performance and reliability. Its low power and extremely small size make it ideal for battery powered applications.


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.  The output power rating is 0.1W.


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