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 Maximum Capacitive Load The DCMFW02 series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the statup time. Maximum capacitance can be found in datasheet. Overload Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into specified range. 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 poewr is supplied over long lines oand output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure the stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100KHz) capacitor of a 8.2µF for the 5V input device, a 3.3µF for the 12V input devices and a 1.5µF for the 24V and 48V devices. Output Ripple Reduction A good quality low ESR capacitor placed as close as practically possible 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. 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 105ºC. The derating curves are determined from measurements obtained in a test setup. 2/1/2017 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 DCMFW02 SERIES 2 Watts DC/DC Converter Single and Dual Output COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
