These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules; however they may not meet all listed specifications. 2. We recommend to protect the converter by a slow blow fuse in the input supply line. 3. Other input and output voltages may be available, please contact factory. 4. Natural Convection is about 20LFM, but is not equal to still air (0LFM). 5. It is not recommended to use water-washing process on SMT units. *Due to advances in technology, specifications subject to change without notice. 1/12/2017 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 2 of 5 DCMSE02-HI SERIES 2 Watts DC/DC Converter Single and Dual Output Rev A DERATING CURVES MECHANICAL DRAWINGS Connecting Pin Patterns Pin 1 7 8 9 10 16 Pin Connections Single Output Dual Output -Vin -Vin NC NC NC Common +Vout +Vout -Vout -Vout +Vin +Vin Notes: All dimensions in mm (inches) Tolerance: X.X±0.5 (X.XX±0.02) X.XX±0.25 (X.XXX±0.01) Pins ±0.05 (±0.002) 1/12/2017 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 5 Rev A DCMSE02-HI SERIES 2 Watts DC/DC Converter Single and Dual Output TEST SETUP 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 Maximum Capacitive Load The DCMSE02-HI 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 startup time. For optimum performance we recommend 100µF maximum capacitive load for dual outputs and 330µF capacitive load for single outputs. The maximum capacitance can be found in data sheet. 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 lines and 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 stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100KHz) capacitor of a 2.2µF for the 5V input devices, a 1.0µF for the 12V input devices and a 0.47µF for the 24V input devices. 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. 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 90ºC. The derating curves are determined from measurements obtained in a test setup. 1/12/2017 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 DCMSE02-HI 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.
