Temperature Derating Curve: The DC/DC converter will operate over a wider temperature range if less power is drawn from the output and the device is already running. The temperature derating curve shows the operating power-temperature range. As shown below. 10. Switching Frequency: The nominal operating frequency of the DC/DC converters. 11. Input to Output Isolation: The dielectric breakdown strength test between input and output circuits. This is the isolation voltage the device is capable of withstanding for a specified time, usually 1 second or 1 minute. 5/10/2016 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: [email protected] Page 6 of 7 Rev A DCMRD5 SERIES 5 Watts Isolated DC/DC Converters Single and Dual Output COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
