Power Supply Unit Basics in Telecom

What Is a Power Supply Unit?

A Power Supply Unit in telecom acts as the backbone of your network’s electrical system. You use it to convert incoming AC power from the grid into the DC power that telecom devices require. This conversion process ensures your equipment receives the right type of energy, keeping your network stable and operational.

You will find several types of Power Supply Units in telecom infrastructure:

• Basic PDUs distribute power without extra features.

• Metered PDUs let you monitor power locally.

• Monitored PDUs allow remote tracking of power use.

• Switched PDUs give you remote control over outlets.

• Intelligent PDUs combine monitoring and control for advanced management.

These units are designed for high reliability, so your communication stays uninterrupted even in demanding conditions.

Why Stable Power Matters

Stable power is essential for telecom networks. If your equipment receives unstable or fluctuating power, you risk outages, data loss, or even hardware damage. A Power Supply Unit provides the necessary energy to keep your devices running and ensures continuous communication. It delivers stable and efficient power, which is vital for networks in both cities and remote areas.

Tip: Reliable power means fewer interruptions and less maintenance for your network.

Here is a quick look at typical voltage ranges for telecom power systems:

Rectifiers and Their Role

What Is a Rectifier?

You rely on rectifiers to convert alternating current (AC) from the power grid into direct current (DC) that telecom equipment can use. This process is essential because most telecom devices, such as routers and switches, require stable DC power to operate efficiently. Without rectifiers, your Power Supply Unit would not deliver the right type of energy, and your network could face interruptions or equipment damage.

The global demand for rectifiers continues to grow as telecom networks expand.

• The global telecom rectifier module market reached USD 2.8 billion in 2024.

• Experts expect the market to grow at a 6.1% CAGR from 2025 to 2033.

• By 2033, the market could reach USD 4.75 billion.

This growth shows how important rectifiers are for modern telecom infrastructure.

Rectifier Functions in Telecom PSUs

You use rectifiers in your Power Supply Unit for several critical functions. First, rectifiers convert AC to DC, which is necessary for powering DC devices like telecom small cells. They also regulate the voltage output, usually to a standard 48V DC, which matches the requirements of most telecom equipment. Rectifiers help charge backup batteries, so your network keeps running during power outages. When you install a rectifier, you ensure that your equipment receives clean, stable power and that your network remains reliable even when the main power source fails.

Modern rectifiers improve the efficiency of your Power Supply Unit in several ways:

• Many rectifiers now achieve up to 97% efficiency, so only a small amount of energy is lost during conversion.

• Leading companies produce rectifiers with efficiencies around 96%, which helps you save on energy costs.

• About 70% of new telecom setups, including 5G networks, use advanced rectifiers to support efficient communication.

Switchmode technology has made rectifiers even more efficient, raising performance from 85-90% to 92-96%. New materials like silicon carbide and gallium nitride push efficiency closer to 98%. These improvements mean you can reduce energy consumption and lower your operating costs.

Note: High-efficiency rectifiers not only save energy but also reduce heat, which means less cooling is needed for your equipment.

How Rectifiers Work in Power Supply Units

The Rectification Process

You start with alternating current (AC) from the power grid. Telecom equipment cannot use AC directly, so you need to convert it to direct current (DC). Rectifiers handle this conversion inside your Power Supply Unit. Here is how the process works:

• Rectifiers take in AC power and allow current to flow in only one direction.

• Half-wave rectifiers use just one half of the AC cycle, but this method is not efficient for telecom needs.

• Full-wave rectifiers use both halves of the AC waveform. This approach gives you a more stable and efficient DC output.

• The rectifier then delivers a steady 48V DC output, which is the standard for most telecom systems.

You rely on this process to power your network equipment safely and efficiently. Full-wave rectification ensures you get the most reliable and consistent power for your operations.

Integration with Telecom Power Systems

You integrate rectifiers into your telecom Power Supply Unit to create a seamless power management system. Modern rectifiers, like those in ESTEL’s solutions, use advanced technologies to boost efficiency and reliability. You benefit from features that support both your equipment and your backup batteries.

You also get advanced battery management when you use ESTEL’s rectifier systems. These features help you keep your backup batteries healthy and ready for emergencies.

You can manage your power and batteries with confidence, knowing your system will respond to changes and protect your equipment.

Benefits for Reliability and Efficiency

When you use high-efficiency rectifiers in your Power Supply Unit, you see real improvements in reliability and cost savings. Here are some of the key benefits:

• You get real-time monitoring of voltage, current, and temperature.

• You can detect wear or abnormal operation early.

• You receive alerts if your system moves away from optimal performance.

Tip: High-efficiency rectifiers not only save you money on energy bills, but they also reduce the need for extra cooling. This means your equipment lasts longer and your network stays online, even during heavy use.

You ensure your telecom network runs smoothly and efficiently by choosing the right rectifier system. ESTEL’s solutions help you maintain stable DC output, support backup batteries, and keep your network reliable in any condition.
