With input capacitor 22µF/50V (CHEMI-CON KY) for input voltage >28VDC, input voltage allows 32VDC, max. 2. Other input and output voltages may be available, please contact factory. 3. It is recommended to protect the converter by a slow blow fuse in the input supply line. 4. Natural convection is about 20LFM but is not equal to still air (0 LFM) 5. To meet EN55022 Class A,B an external filter is necessary. Please contact factory 6. This series can meet EN61000-4-4 by adding a capacitor across the input pins. Suggested capacitor: 22µF/50V (CHEMI-CON KY). *Due to advances in technology, specifications subject to change without notice.

Scope measurement should be made by using a BNC socket, measurement bandwidth is 020MHz. Position the load between 50mm and 75mm from the DC/DC Converter. TECHNICAL NOTES Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.3µF capacitors at the output. Maximum Capacitive Load The DCMAR1 series has limitation of maximum connected capacitance on the output. The power module may operate in current limiting mode during start-up, affecting the ramp-up and startup time. Maximum capacitance can be found in the data sheet. 3/9/2017 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 3 of 4 Rev A DCMAR1 SERIES 1A DC/DC Switching Regulator Single Outputs COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
