The ECHVR Series is an economical and versatile regulated high voltage DC to DC converter perfectly suited for small, portable, high performance equipment requiring high voltage biasing. Designed for affordability and reliability, the ECHVR Series is manufactured using all surface mount construction and tested using state-of-the-art automatic test equipment.
The ECHVR Series includes a range of models with output voltages up to 10kV. Fully encapsulated in a compact (1.8”L x 1.0”W x 0.40”H) package, the ECHVR Series has easy-to-use features that enable the designer to quickly integrate high voltage into any design. A high impedance programming input makes the ECHVR Series very easy to use. The ECHVR also has a high voltage monitor output (VMON) that provides the user with a low voltage representation of the high voltage output.
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, making it ideal for battery powered applications.
The device operates directly from 5V or 12V input and the output power rating is 1W. 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 ECHVR Series is designed for stable operation over a wide temperature range of -55°C to +70°C.
