Absopulse Electronics‘ HVI 500-D3G series of high input voltage, ultra-rugged, IP66-rated dc-dc converters are designed and built for extreme applications that require a waterproof, dust-proof, sand-proof, oil-, fire- and/or explosion-proof solution. They are typically used in heavy industry, mining, marine, military and power generation and distribution environments.
The 500W converters operate from a 600Vdc input voltage, with a 400- to 800-Vdc input range. All critical components on the primary side are designed and tested for corona inception levels that are far higher than the operating voltages. The design is verified for 5600Vdc input-to-output isolation, and production level testing is 4300Vdc. The converters deliver voltages of 24-, 36-, 48-, or 110-Vdc. Custom output voltages are also offered.
The converters utilize Absopulse’s new proprietary KHR 301 topology which enables a significantly more compact construction than earlier high input voltage designs at the same level of output power. The converters measure 360 x 160 x 90 mm.
