Product Q&A

Q:Can the output voltage be customized for non-standard telecom equipment?

Yes. While -48VDC is the standard, our system can be customized to provide 24VDC, 110VDC, or 220VDC based on your specific requirements.

Q:What is the benefit of the Class I surge protection included in this system?

Class I protection is designed to handle high-energy surges, such as direct lightning strikes. It ensures that your communication network remains safe even in extreme weather conditions.

Q:Does the system support Lithium (LiFePO4) batteries?

Absolutely. The system includes optimized charging curves for both Lead-acid (VRLA/Gel) and Lithium Iron Phosphate (LiFePO4) batteries, managed by an intelligent monitoring module.

Q:How does the remote monitoring function work?

You can connect the system to your local network or the internet via the Ethernet port. Using our dedicated software, you can view real-time data, history logs, and receive instant alarm notifications.

Q:Is the system suitable for outdoor base stations?

The system is designed for indoor installation. However, when housed in a suitable outdoor cabinet with proper thermal management, it is ideal for outdoor communication base stations.
