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 80%, 3000VDC I/O isolation, remote on/off control, and -40°C to +85°C operating temperature range. The DCBOB3 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.
