Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500KHz. Peak-to-Peak Output Noise Measurement Test Use a Cout 0.47µF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20MHz. Position the load between 50mm and 75mm from the DC/DC converter. TECHNICAL NOTES Input Source Impedance The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long line and output loading is high, it may be necessary to use a capacitor on the input to ensure startup. By using a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100kHz) capacitor of a 10µF for the 12V input devices and a 4.7µF for the 24V input devise and a 2.2µF for the 48V devices. Capacitor mounted close to the power module helps ensure stability of the unit. 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 DCMKE10-HI 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 the startup time. Connect capacitors at the point of load for best performance. Maximum capacitance can be found in data sheet. Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module, and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 95ºC. The derating curves are determined from measurements obtained in a test setup. 5/4/2017 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 4 of 5 Rev A DCMK10-HI SERIES 10 Watts DC/DC Converter Single and Dual Outputs COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
