This series of rugged DC-DC converters is designed for an operating life of up to 20 years in railway environments. This design eliminates optocouplers in the feedback loop, which contributes to an MTBF of over 175,000 hours at 45°C. Very low component count, large design headroom, and full electronic protection also contribute to the long operating life of the units.
The BHR 65X2-4U2NF is a 1kW addition to ABSOPULSE’s line of convection cooled, high-reliability, industrial DC-DC converters. This design encompasses electrical and mechanical features that contribute to an operating life of up to 20 years. The units are suitable for heavy-duty industrial applications where fan cooling is not permitted and in which the replacement or repair of electronic equipment is logistically difficult or costly.
The HVI 500P-D3 series of ultra-rugged, high input voltage, IP66-rated DC-DC converters target extreme applications that require a waterproof, dust-proof, sand-proof, oil-proof solution. They are suitable for mining, marine, military, heavy industry, power generation and distribution, telecom and other severe environments.
The DCR 100R and DCR 150R are recent additions to ABSOPULSE Electronics′ line of rugged, railway quality dc-dc converters. They meet the requirements of EN50155 for electronic equipment used on railway rolling stock. In addition, with an input voltage surge withstand capability of 385Vdc for >1 minute (3.5Vn for 20msec min.), they comfortably meet RIA12, which is the general specification for the protection of traction and rolling stock equipment from transients and surges in DC control systems.
The DHR 150-24 is the latest addition to ABSOPULSE′s line of wide input range, long-life, power conversion products developed for rugged industrial environments.
