The Cence Telecom Power System

Reduce cable size and voltage drop

Class 4 power systems (like Cence) can supply higher voltages (up to 450V DC), making them superior to 48V DC systems to remotely power telecom.

A Class 4 Power System For Telecom

Cence HVDC is a Class 4 Power (CL4) system, ideal for telecom applications.

The NEC added the Class 4 rating in November 2022 in Article 726. This rating is applied to power systems that can provide up to 450V DC, and have fault-management built-in for safety. You can think of Class 4 rated power systems as a combination of Class 2 power systems (such as PoE), and traditional AC power. Class 2 and Class 4 both provide suitable protection from fire and shock hazards, but PoE can only provide up to 100 W of power. Read our blog to learn more about Class 4 Power Systems.

Fault-Managed for Safety

Cence intelligently stops power as soon as a fault is detected.

A Class 4? Higher Voltages

Reduce telecom project capital costs associated with cabling. Class 4 power systems provide higher voltages (up to 450V DC).

48V DC cable

Cables in low voltage, high power, applications (such as traditional telecom rectifiers) require larger cable gauges to support the current needed.

450V DC cable

Cables in Class 4 systems have a gauge that is about 10x smaller than the gauge of a cable with 48V DC running through it, carrying the same amount of power.

Why Class 4? DC Power

Boost battery backup capacity, and reduce power consumption with DC Power.

Reliable 5G Internet

Increase battery backup capacity

Batteries only store DC power (not AC). Distribute DC power with Cence to improve battery capacity, and keep telecom sites in operation for up to 8 hours if power fails

Reduce Operating Costs

Reduce voltage drop along cables

Save on operating costs by reducing voltage drop with Cence. Cence distributes DC power, and less typical line losses affect DC, as opposed to AC power.

Why Class 4? Fault Managed For Safety

Onboard computers in the Cence Class 4 power system continuously monitor cables for faults, such as human touch, and stop power immediately if one is detected. This enables Cence to distribute up to 450V DC of power to telecom applications, while safely making use of low-voltage wiring practices.

Prepare for Hybrid Fibre Cables

Implementing a Class 4 DC power system, like Cence, makes the transition to hybrid cables more streamlined.

Hybrid Fibre Cables

A hybrid cable incorporates optical fibers (for data transmission) and copper wires (for power transmission) within the same jacket. They are a distribution medium for both Class 4 power and 5G. Hybrid cables enable long-distance power supply while ensuring high-speed data transmission.
