Характеристики
Products 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.
This one link photo is expensive one no have capacitance and ripple is small about 100mv.and we have cheap version have capacitance and ripple is larger about 300-400mv .The detals please ask customer service

PIN ASSIGNMENT
Pin | Name | Description |
1 | VA1 | RX Input (1). This input pin is used in conjunction with VA2 and connects to the centre tap of the transformer connected to pins 1 & 2 of the RJ45 connector (RX) - it is not polarity sensitive. |
2 | VA2 | TX Input (2). This input pin is used in conjunction with VA1 and connects to the centre tap of the transformer connected to pins 3 & 6 of the RJ45 connector (TX) - it is not polarity sensitive. |
3 | VB1 | Direct Input (1). This input pin is used in conjunction with VB2 and connects to pin 4 & 5 of the RJ45 connector - it is not polarity sensitive. |
4 | VB2 | Direct Input (2). This input pin is used in conjunction with VB1 and connects to pin 7 & 8 of the RJ45 connector - it is not polarity sensitive. |
5,6 | NC | No Connection |
7 | -VDC | DC Return. This pin is the return path for the +VDC output. |
8 | +VDC | DC Output. This pin provides the regulated output from the DC/DC converter. |
9,10 | NC | No Connection |
