Welcome to Veracity

| POE systems deliver power and data on network cables, saving installation time and costs

| Three IEEE standards specify up to 15W, 30W and 90W PSEs, and lower powers at the PD

| Veracity can assist with POE system design and power budgets




Power Over Ethernet

“Power over Ethernet (POE) allows both data and power to be transmitted over Ethernet network cables. It eliminates the need for separate power cables, simplifying installations, reducing costs and providing flexibility in powering various devices. Power Delivery: Low-voltage DC power (typically between 15 and 90 watts) is supplied by a POE-enabled network switch, a POE injector, or by a powered device such as HIGHWIRE, LONGSPAN or CAMSWITCH. Ethernet Cable: POE typically utilises Cat5e or Cat6 for power and data transmission. Higher power POE uses all pairs for power transmission. The heavier gauge CAT6 cable is more efficient for power transmission and with lower power losses over distance. POE Standards: IEEE 802.3af, 802.3at and 802.3bt define up to 15W, 30W and 90W POE standards respectively. POE Terminology: Power Sourcing Equipment (PSE) is the power source, such as an injector, whilst the Powered Devices (PD) is the device which is powered, such as an IP cameras. Power to POE systems is limited by the total amount of power available from switch, injector or other device. Proper power management is essential to ensure that the total power consumption of connected devices does not exceed the available power budget. Determining the correct power budget level in a system design is one of the most misunderstood aspects of applying POE in the real world and is an area where Veracity’s experienced pre-sales support engineers can help.“
