DCHAA SERIES 5~6 Watt DC/DC Power Converters Rev B Wall Industries, Inc. FEATURES Size: 1.25 x 0.80 x 0.50 inches 31.7 x 20.3 x 12.65 mm -40°C to +85°C Operating Temperature Range 5~6 Watts Output Power 4000VACrms I/O Isolation Voltage RoHS Compliant 6000Vpk Isolation Test Voltage No Minimum Load Requirement Short Circuit Protection: Continuous & Auto-Recovery Single and Dual Outputs Over Voltage Protection: Clamp Mode High Efficiency up to 85% 24-Pin DIP Package with Industry-Standard Footprint DESCRIPTION The DCHAA series of DC/DC power converters provides up to 6 Watts of continuous output power in a 1.25” x 0.80” x 0.50” 24-pin DIP package. This series consists of single and dual output models with 2:1 input voltage ranges of 9~18VDC, 18~36VDC, and 36~75VDC. Some features include high efficiency up to 85%, 4000VACrms I/O isolation, -40°C to +85°C operating temperature range, and no minimum load requirement. The DCHAA series is RoHS and UL94V-0 compliant. These converters 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.
