How to use

Mount the SPAN02C-05 onto a PCB using the SIP through-hole pins and ensure correct polarity of the input connection. Provide an input source within the specified 36–75 V DC range and verify the output with a multimeter before connecting sensitive loads. For stable operation, place the module away from heat sources and follow standard PCB layout recommendations for power modules, including short traces for input/output and adequate grounding.

Recommendations

Do not exceed the rated input voltage range or output current. Use appropriate input filtering and transient protection when connecting the converter to noisy power lines. Allow sufficient spacing around the module for cooling and avoid covering it with insulating materials.
