NOTES
1. # for each output.
2. It is recommended to protect the converter by a slow blow fuse in the input supply line.
3. Other inputs and outputs may be available, please contact factory.
4. To meet EN61000-4-4 & EN61000-4-5 and external capacitor across the input pins is required. Suggested capacitor: 220µF/100V.
5. To meet EN55022 Class A, B an external filter is necessary. Please contact factory.
6. Natural Convection is about 20LFM but is not equal to still air (0 LFM).
*Due to advances in technology, specifications subject to change without notice.

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 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.
