This series consists of non-regulated single and dual output models with 5, 12, 15, and 24VDC nominal input voltages. Some features include high efficiency up to 82%, 6.4KVDC I/O isolation (8KVDC optional), -40°C to +85°C operating temperature range, and no minimum load requirement. The DCHBA1 series is RoHS and UL94V-0 compliant. These converters have IEC 60950-1, EN 60950-1, IEC 60601-1 and EN 60601-1 medical approvals and are best suited for use in battery operated equipment, measurement equipment, telecom, wireless networks, industry control systems, and anywhere where isolated and compact size are required.
