Telecom UPS Solution

Modern telecom infrastructure depends on stable, clean and continuous power. Core network rooms, ISP facilities, telecom switching centers, transmission hubs and large communication equipment rooms cannot afford unexpected shutdowns caused by utility outages, voltage fluctuation, frequency instability or poor grid quality.

For medium and large telecom power applications, our OSP33 Three Phase Online UPS 60–200kVA provides reliable three-phase power protection with online double-conversion technology, wide input voltage adaptability, high efficiency and optional remote monitoring. It is designed to protect critical telecom loads such as transmission equipment, network servers, switches, routers, security monitoring systems and communication control equipment.

Why Telecom Sites Need Reliable Backup Power?

Telecom networks are expected to operate 24/7. When a core network room or transmission hub loses power, the impact is not limited to one device. It may affect signal transmission, data communication, internet access, customer service continuity and emergency communication reliability.

In many telecom projects, power problems are caused not only by complete outages, but also by unstable utility input, voltage sag, surge, frequency fluctuation, harmonics and generator transition. Sensitive telecom and IT equipment requires stable sinusoidal output power to avoid abnormal restart, communication interruption or hardware damage.

The OSP33 60–200kVA online UPS helps telecom facilities maintain power continuity by converting unstable grid power into stable three-phase output power. It can also provide backup time through external battery configuration, allowing the system to bridge short outages, generator startup time or controlled shutdown requirements.

Common Power Challenges in Telecom Applications

Utility Outages

Power interruptions can shut down telecom equipment within seconds. For telecom operators, ISP companies and network infrastructure providers, downtime may lead to service complaints, emergency maintenance and business loss.

Unstable Grid Voltage

Telecom power rooms may face voltage sag, surge or unstable input caused by weak grid infrastructure, generator switching or high-load equipment nearby. The OSP33 UPS supports a wide input voltage range, helping improve adaptability in complex power environments.

Frequency Fluctuation

Some telecom sites use grid power and generator backup together. During generator startup or power transition, frequency instability may affect sensitive loads. An online UPS can provide stable output frequency in battery mode.

Harmonics and Poor Power Quality

Sensitive telecom equipment requires clean power. Harmonics, distortion and poor power quality may reduce equipment reliability. The OSP33 UPS is designed with high input power factor and low input current harmonics, helping reduce power pollution and improve system performance.

Backup Time Uncertainty

Different telecom sites require different backup time. Some projects only need UPS backup for generator startup, while others need longer battery autonomy. Backup time depends on actual load, battery capacity and battery configuration, so final runtime should be calculated according to the project requirement.

Lack of Remote Visibility

Telecom power rooms often require centralized monitoring. Without remote UPS status and alarm visibility, maintenance teams may not detect battery or power issues in time. The OSP33 UPS supports communication interfaces such as USB, CAN, RS485 and optional SNMP card, making it suitable for remote monitoring applications.

Recommended Telecom UPS System Configuration

For medium and large telecom power rooms, the recommended system configuration can be:

Utility Grid / Generator
→ OSP33 Three Phase Online UPS 60–200kVA
→ External Battery Cabinet
→ Maintenance Bypass / Distribution Cabinet
→ Telecom Loads
→ SNMP / RS485 Remote Monitoring

Core UPS Unit

The OSP33 Three Phase Online UPS 60–200kVA is the core power protection unit of this solution. It uses online double-conversion technology to provide stable and clean three-phase output power for critical telecom equipment.

Battery Backup System

The OSP33 series uses a default ±240VDC battery system, with battery quantity options available according to project configuration. External battery cabinets can be selected according to required backup time and site load.

Backup time needs to be calculated based on actual load power, battery quantity, battery capacity and required autonomy.

Monitoring System

For remote management, the system can be configured with communication options such as USB, CAN, RS485 and optional SNMP card. This helps telecom operators monitor UPS status, alarms and operating conditions more efficiently.

Parallel Redundancy Option

For higher reliability or larger capacity requirements, the OSP33 series supports parallel operation up to 8 units. This can help telecom customers design redundancy or future capacity expansion according to project needs.

Distribution and Bypass

For telecom power rooms, maintenance bypass, PDU or distribution cabinet can be added according to the installation design. These parts need to be confirmed according to site wiring, load distribution and maintenance requirements.

Application Scenarios

Telecom Power Rooms

The OSP33 60–200kVA UPS is suitable for telecom power rooms that require three-phase power protection for communication equipment, transmission systems, control cabinets and supporting IT loads.

ISP Facilities

For ISP companies, network uptime is directly related to service quality. The OSP33 UPS can help protect routers, switches, servers, storage equipment and network security systems from power interruptions and voltage instability.

Network Aggregation Sites

Network aggregation sites often connect multiple access points and communication links. Power failure at these sites may affect a larger service area. A three-phase online UPS helps provide centralized backup power protection for critical network equipment.

Telecom Switching Centers

Telecom switching centers require stable, clean and continuous power for switching equipment, control systems and monitoring devices. The OSP33 UPS provides online double-conversion protection and supports remote monitoring options.

Transmission Hubs

Transmission hubs handle important communication traffic and require reliable backup power. The OSP33 UPS can be configured with external battery cabinets to match different runtime requirements.

Security Monitoring and Control Rooms

Many telecom operators also operate security monitoring and network operation rooms. The OSP33 UPS can protect monitoring servers, display systems, control terminals and related critical loads.

Benefits of Our Telecom UPS Solution:

Stable Power for Critical Telecom Loads

With online double-conversion technology, the OSP33 UPS helps isolate critical telecom equipment from unstable grid power, voltage fluctuation and frequency problems.

Suitable for Medium and Large Telecom Sites

The 60–200kVA power range makes this solution suitable for telecom power rooms, ISP facilities, network hubs and core communication rooms that require higher capacity than small rack UPS systems.
