Absopulse Releases 700Vdc Input, 50W DC-DC Converter for Rugged Industrial Applications

Absopulse Electronics’ HVI 50 series, a 50W rugged, industrial quality dc-dc converter, accepts 700Vdc nominal input voltage, and has an input range of 600 to 800Vdc. All critical components on the primary side are designed and tested for corona inception levels that are significantly higher than the operating voltages, ensuring high reliability and long operating life of the units. (Input to chassis/output isolation is 3000Vdc and it is type tested to 5600Vdc).

Standard output voltages are 12, 24 and 48Vdc, with other output voltages available on request. The converter is filtered to meet EN55022 Class A EMI conducted and radiated with wide margins and it is designed to meet EN 60950 and related standards.

The HVI 50 is ruggdized to ensure immunity to shock and vibration (EN61373/IEC61373 compliant) and it is conformal coated for protection from moisture, humidity and airborne contaminants. Additional ruggedizing is available for operation in severe environments. The unit is housed in a vented enclosure that measures 114 x 51 x 201mm and weighs 0.8kg. Indicators include a green "Output ON" LED that is visible through the cooling slots. Cooling is by conduction to customer heat sink or chassis and by natural convection; it requires no fans.

Each HVI 50 unit is priced in the US$168 range in quantities of 100.
