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 4.7µF 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 Over Load Protection To provide hiccup model protection in a fault (output over load) condition, the unit is equipped with internal current limiting circuitry and can endure overload for an unlimited duration. Over Voltage Protection The output over voltage clamp consists of control circuitry, which is independent of the primary regulation loop that monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop. This provides a redundant voltage control that reduces the risk of output over voltage. The OVP level can be found in data sheet. Input Source Impedance The power module should be connected to a low ac-impedance 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 on the input to ensure startup. By using a good quality low Equivalent Series Resistance (ESR <1.0 at 100kHz) capacitor of 10µF for 12V input devices, a 4.7µF for 24V input devices, 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 4.7µF capacitors at the output. 12/8/2017 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 5 of 6 Rev A DCMRH15 SERIES 15 Watts Medical DC/DC Converter Single and Dual Output Maximum Capacitive Load THE DCMRH15 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. The maximum capacitance can be found in the 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. COMPANY INFORMATION Wall Industries, Inc. has created custom and modified units for over 50 years.
