Power over Ethernet (PoE): Intelligent Power Meets Data Transmission
Cincon’s Optimized Power Solutions for Modern Networked Devices
FORTEC Switzerland highlights Cincon’s introduction to Power over Ethernet (PoE)—a key technology enabling the simultaneous transmission of power and data over a single Ethernet cable. Through RJ45 connectors, PoE simplifies installation, reduces cabling costs, and supports a wide range of smart and connected devices.
What Is PoE and How Does It Work?
A complete PoE system consists of two core components:
- Power Sourcing Equipment (PSE) such as switches, routers, and hubs that provide power.
- Powered Devices (PD) including IP cameras, VoIP phones, wireless access points, and smart lighting.
This setup eliminates the need for separate power cables, accelerating deployment and reducing total system cost.
PoE technology is based on industry standards - 802.3af for low-power devices, 802.3at (PoE+) for mid-range applications like video phones, and 802.3bt (PoE++) for high-power equipment such as laptops and HD video systems. Each evolution delivers increased wattage and voltage ranges to support more demanding devices.
PoE is effective up to 100 meters from the power source. To counteract voltage drops over longer distances, higher supply voltages between 48 V and 56 V are typically used. Cincon offers a wide selection of 48 V, 54 V, and 56 V models, making them ideal for both short- and long-distance Ethernet-based power delivery.

Product Examples for PoE Projects
Cincon’s CFM500S AC/DC open frame series includes advanced protection features like over-temperature, over-voltage, over-current, and short-circuit safeguards. The series also supports key functions such as standby outputs, power signals, and remote monitoring. With an operating case temperature from -40 °C to +85 °C and compliance with MIL-STD-810F, it is suitable for demanding environments.
The CQB75W14 DC/DC converter series offers an input range from 12 to 160 VDC, output voltages from 5 V to 54 V, and reliable protection against various failure modes. It supports remote on/off control and meets shock, vibration, and altitude standards, making it ideal for robust PoE infrastructure.
