HVM Technology, Inc. UMHV1240

The UMHV Series is a family of ultra-miniature single-output DC to DC converters supplying up to 5 kV in 0.125 cubic inches (0.5"×0.5"×0.5"). 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 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, typically 1/10th of that of similar devices on the market, making it ideal for battery powered applications. The devices operate directly from 5 VDC ±0.5 VDC input. Output voltage is independent of input power voltage and is proportional to the programming voltage (0 to |N+| produces 0 to full scale output) and features excellent linearity. The output power rating is 0.5 W and the input to output isolation is ±500 V. The UMHV Series is very stable over a wide operating temperature range.
