NOTES
1. Din Rail Mounting is available for this series. To indicate Din Rail bracket add –D to model number. Ex. DCWIM20-24S51C-D
2. 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. It is recommended to protect the converter by a slow blow fuse in the input supply line.
5. Other input and output voltages may be available, please contact factory.
*Due to advances in technology, specifications subject to change without notice.

TEST SETUP
Peak-to-Peak Output Noise Measurement Test
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
Remote On/Off
Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and off during a logic low. To turn the power module
on and off, the user must supply a switch to control the voltage between the on/off terminal and the –Vin terminal. The switch can be an open collector or
equivalent. A logic low is 0V to 1.2V. A logic high is 3.5V to 12V. The maximum sink current at the on/off terminal (Pin 1) during a logic low is -100µ A.
Overload Protection
To provide hiccup mode protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure
overload for an unlimited duration.
Overvoltage Protection
The output overvoltage clamp consists of control circuitry, which is independent of the primary regulation loop that monitors the voltage on the output
terminals. The control look 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 overvoltage. OVP 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
Resistor (ESR <1.0Ω at 100KHz) capacitor of a 10µF for the 24V and 48V 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 4.7µF capacitors at the output.
Maximum Capacitive Load
The DCWIM20 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. The maximum capacitance can be found in datasheet.
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.
