Frequently Asked Questions

Why use 48V DC in telecom systems?

48V DC is standard in telecom because it offers a safe voltage level while minimizing power loss over long cable runs. It provides efficient power distribution with reduced current, lowering resistive losses and cable costs.

What is the difference between 24V and 48V power systems?

48V systems deliver the same power at half the current of 24V systems, reducing I²R losses and allowing thinner cables. This makes 48V more efficient for high-power or long-distance applications like telecom and data centers.

Do you offer custom power solutions?

Yes, EVS Group provides OEM/ODM services. We can customize voltage, form factor, communication interfaces, and enclosure design to meet your specific requirements.

Are your inverters pure sine wave?

Yes, our telecom and data center inverters produce pure sine wave output, ensuring compatibility with sensitive electronic equipment and reducing harmonic distortion.

Can your systems be monitored remotely?

Most of our power systems include RS485 interfaces with Modbus protocol for remote monitoring, alarms, and control. SNMP gateways are also available for network integration.
