SDAPO PM1202 12v poe ModeA or ModeB DC to DC power module

Product Description

You are welcome to customize the POE modules of various sizes and appearances and function.
The layout is required to receive the initial research and development expenses.
After ordering a certain number of modules (usually 5000 pieces), the r&d cost can be deducted.
After the sample is qualified, batch production.
