Why 48V DC Is the Telecom Standard

Technical and Historical Reasons

You may wonder why 48V DC became the standard in the telecom industry. The answer comes from both history and technology. Early telephone systems used local batteries, and 48V DC proved reliable over time. This voltage level became common because it worked well with the equipment and kept people safe during maintenance.

Here is a table that shows why 48V DC stands out:

ESTEL supports this standard with products like the DC48V Rack Mount Rectifier and Hybrid Telecom Power System. These solutions deliver reliable power to your telecom equipment and help you maintain safe, efficient operations.

Comparison with Other Voltages

When you compare 48V DC to other voltage options, you see clear advantages for telecom applications. Higher AC voltages can be dangerous for human contact and may cause more corrosion. In contrast, 48V DC is safe for technicians and helps protect your equipment.

You benefit from 48V DC because it offers:

• Lower risk of electric shock, making your work environment safer.

• Stable voltage delivery, which keeps your telecom network running smoothly.

• Compatibility with a wide range of telecom equipment, making upgrades and maintenance easier.

ESTEL’s power systems use 48V DC to give you these advantages, ensuring your telecom infrastructure remains efficient and secure.

Efficiency in Telecom Power Systems

Power Efficiency and Transmission

You want your telecom power system to deliver the highest efficiency possible. When you use 48V DC, you see a dramatic improvement in power efficiency compared to lower voltages. For example, increasing voltage from 12V to 24V reduces cable losses by a factor of four. Moving from 24V to 48V decreases losses by a factor of sixteen. This means you can transmit more power over longer distances without wasting energy as heat. Higher voltages also let you use more powerful devices and increase the total capacity of your telecom network.

However, when you compare 48V DC to even higher voltages like 230V DC, you notice that 48V DC still has some power losses. Yet, 48V DC strikes the right balance between safety and efficiency for telecom applications. You get enough efficiency to keep your operational costs low, while still maintaining a safe environment for technicians.

ESTEL’s Telecom Power System and Rectifier System help you maximize efficiency. These systems use advanced rectifier designs that reach up to 98% efficiency ratings. High efficiency means less energy is lost during AC to DC conversion, so you save on electricity bills and reduce your carbon footprint. Intelligent monitoring features let you track system performance in real time, so you can quickly identify and fix any issues that might affect efficiency.

Equipment Compatibility

You need your telecom power system to work seamlessly with equipment from different manufacturers. The 48V DC standard ensures broad compatibility and easy integration. Most telecom equipment worldwide is designed to operate at 48V DC, so you can mix and match devices without worrying about voltage mismatches.

This level of compatibility means you can upgrade your telecom power system or add new components without major changes. ESTEL’s Telecom Power System and Rectifier System both follow these global standards. You benefit from a flexible, future-proof network that supports growth and new technologies. Monitoring tools built into these systems also help you ensure that all connected equipment operates at peak efficiency.

Operational Cost Benefits

You want your telecom power system to deliver long-term savings. Using 48V DC can cut your energy costs by up to 75% over a ten-year period, thanks to reduced energy losses. Maintenance costs also drop to just 7% of what you would spend on older systems. Modern rectifiers, like those in ESTEL’s solutions, achieve efficiency ratings over 97%, with some reaching as high as 98%. This high efficiency translates directly into lower operational costs.

ESTEL’s Telecom Power System and Rectifier System offer several features that help you save money:

With these advantages, you can expect fewer site visits, lower electricity bills, and a more reliable telecom network. Monitoring tools give you real-time insights, so you can make informed decisions and keep your system running at peak efficiency.

Safety Advantages of 48V DC

Safe Voltage Threshold

You want to work in an environment where safety comes first. The voltage level in your telecom power system plays a major role in protecting you and your team. International safety standards set the safe voltage threshold for human contact at 50 volts DC or less. 48V DC fits comfortably within this range, making it a preferred choice for telecom sites.

• 48V DC is generally considered safe for human contact.

• The safe voltage threshold is about 35 volts AC or less and 50 volts DC or less.

• In certain conditions, the maximum safe voltage is defined as less than or equal to 30 VAC and 60 VDC.

You benefit from this standard because it reduces the risk of electric shock during routine maintenance. Even if you accidentally touch a power line, the probability and severity of shock are much lower than with higher voltages like 220V AC. This safety margin allows you to focus on your work with greater confidence.

Tip: Always exercise caution in wet conditions, as water can increase the risk even at lower voltages.

Fire and Equipment Protection

You rely on your telecom power system to keep your equipment safe and your site secure. 48V DC systems help protect your devices from hazards that can cause downtime or damage.

• 48V DC systems offer both safety and efficiency, shielding equipment from electrical faults.

• Surge protectors designed for 48V DC divert dangerous currents from lightning strikes, keeping your devices safe and extending their lifespan.
