3 Data communication and telecom equipment: used to power network switches, routers, and communication modules in telecom cabinets

4 Test equipment: provides stable power for precision test instruments and measurement devices

5 Medical devices: suitable for low-power medical equipment requiring stable DC power (compliant with relevant safety standards)

6 Embedded systems: ideal for space-constrained PCB applications (compact 1.0"×1.0" size)

7 Battery-powered devices: compatible with 12V/24V battery systems, suitable for portable or mobile devices

注意事项 PRECAUTIONS

1 Input source impedance: Use a low AC-impedance input source; if the source inductance exceeds a few μH, add a 47μF electrolytic capacitor close to the module's input terminal to improve stability

2 Input filtering: For EMC compliance (e.g., EN55022 Class A), use the recommended input filter (1uH inductor +47μF electrolytic capacitor) as per the reference design

3 PCB layout: Adopt multi-layer PCB with large copper areas connected to the module's pins to enhance thermal performance

4 Remote ON/OFF operation: This model uses negative logic (code N); if not using the remote control function, short the ON/OFF pin to the input negative terminal (Vi-). Control can be implemented via an external switch between the ON/OFF pin and Vi- (supports open collector/drain circuits)

5 Output voltage trim: For single output modules, connect an external resistor between the TRIM pin and Vout- to increase the output voltage, or between TRIM and Vout+ to decrease it (max ±10% range). Leave the TRIM pin open if this function is not needed

6 Thermal management: The module uses natural convection cooling; refer to the thermal derating curves to determine the maximum ambient temperature based on input voltage and output power. An optional heatsink can be installed to improve heat dissipation in high-temperature environments

7 Soldering: The module's through-hole pins are designed for wave soldering; do not use reflow soldering processes

8 Input protection: It is recommended to install an external fuse at the front end of the module for input protection

9 Specification updates: Product specifications are subject to change without prior notice; please refer to the latest official documentation for the most accurate information
