Frequently Asked Questions

Find answers to common questions about our products and services

What is PoE and how does it work?

Power over Ethernet (PoE) delivers both data and electrical power over a single Ethernet cable. It allows devices like IP cameras and VoIP phones to be powered without a separate power supply, simplifying installation and reducing costs.

What are the differences between IEEE 802.3af, 802.3at, and 802.3bt?

802.3af (PoE) supports up to 15.4W, 802.3at (PoE+) up to 30W, and 802.3bt (PoE++) up to 60W (Type 3) or 100W (Type 4). Winchen Power offers modules compliant with all three standards.

Can I use PoE with my existing network cables?

Yes, standard Cat5e or higher Ethernet cables can support PoE. However, longer cable runs may experience voltage drop, so proper planning is recommended.

Do you offer custom power solutions?

Yes, we specialize in custom PoE modules, DC-DC converters, and AC-DC power supplies tailored to your specific voltage, current, isolation, and form factor requirements.

What certifications do your products have?

Our products are CE, RoHS, and IEEE 802.3af/at/bt certified. We also comply with ISO9001 quality management standards.
