Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%. 3. “Natural Convection’ is about 20LFM but is not equal to still air (0 LFM). 4. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor: 220µF/100V. 5. Other input and output voltages may be available, please contact factory. 6. It is recommended to protect the converter by a slow blow fuse in the input supply line. *Due to advances in technology, specifications subject to change without notice.

Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20Mhz. Position the load between 50mm and 75mm from the converter. TECHNICAL NOTES 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 its 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 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 24V and 48V devices. Output Ripple Reduction A good quality low ESR capacitor placed as close as practical 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 DCIDW08 series has a 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. 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 105ºC. The derating curves are determined from measurements obtained in a test setup.
