The Importance of Isolation Transformers in PoE Systems
Isolation transformers serve several essential functions in PoE installations:
Electrical isolation:
Isolation transformers provide electrical isolation between the power supply equipment (PSE) and the powered device (PD). This isolation prevents potentially harmful surges, spikes, and ground loop currents from affecting the connected equipment. It increases safety by protecting sensitive equipment and reducing the risk of electrical hazards.

Signal Integrity:
High-quality isolation transformers maintain the integrity of power and data signals transmitted over Ethernet cables. They effectively filter out noise and electromagnetic interference (EMI), ensuring clear and reliable communication between the PSE and PD. This is critical to maintaining consistent network performance and minimising signal degradation.
