The OHM AMERICAS OHD6-4-1 is a robust DC-DC converter designed for demanding applications. This enclosed unit provides four isolated 28V outputs, delivering a total of 56W of power. It operates reliably within a wide temperature range of -55°C to 85°C and features conduction cooling via its base plate.
Key design features include comprehensive protection mechanisms, such as current limit/fold-back, separate over-voltage protection for each channel, and over-temperature shutdown with auto-recovery. The converter also includes reverse polarity protection and requires no external EMI filter. Its compact dimensions (65mm x 50mm x 12.5mm) and chassis mount type make it suitable for integration into various systems.
With its fully enclosed and conformal coated construction, the OHD6-4-1 is well-suited for harsh environments. The unit utilizes a 20-pin connector for interface and is built for reliability, boasting an MTBF of 150,000 hours.
