The DCBOB5 series of isolated DC/DC power converters provides up to 6 Watts of
continuous output power in an industry standard 1.25” x 0.80” x 0.40” shielded metal case.
This series consists of single and dual output models with 4:1 input voltage ranges of 936VDC and 18~75VDC. Some features include high efficiency up to 83%, 3000VDC I/O
isolation, remote on/off control, and -40°C to +85°C operating temperature range. The
DCBOB5 series is RoHS compliant and has short circuit, over load, and over voltage
protection. These converters are best suited for use in battery powered equipment, industrial
applications, process control equipment, distributed power systems, and anywhere where
isolated, tightly regulated voltages and compact size are required.
