Liebert EXS 30kVA 3:3 UPS. Output power factor up to 1, Double conversion efficiency up to 96.2%, LCD screen, internal batteries for standard runtime, Parallel capability for capacity & redundancy

Description

The Vertiv Liebert EXS 30kVA UPS is a transformer-free, high-performance power protection system engineered for modern IT and industrial environments. Using online double-conversion technology, the UPS continuously converts incoming AC power to DC and back to AC, ensuring that connected equipment receives clean, stable, and uninterrupted power even during outages or electrical disturbances.

With its unity output power factor, the Liebert EXS delivers full rated power to critical loads such as servers, networking equipment, medical devices, and automation systems. Its compact footprint and high power density allow deployment in data rooms, network closets, and small to medium-sized IT installations where space is limited.

The system also supports parallel operation with up to four UPS units, allowing organizations to increase power capacity or create redundancy for higher availability. Integrated monitoring, battery management, and optional network communication cards enable remote supervision and improved operational control.

Vertiv Liebert EXS 30kVA UPS – Key Features

1. Online Double-Conversion Technology

The UPS uses online double-conversion technology, which continuously converts incoming AC power to DC and then back to AC. This process completely isolates connected equipment from power disturbances such as voltage spikes, sags, frequency fluctuations, and electrical noise, ensuring clean and stable power at all times.

2. Unity Output Power Factor (PF = 1.0)

With a unity output power factor, the UPS can deliver the full 30kW of usable power to connected equipment. This means more efficient power utilization and the ability to support more IT equipment such as servers, networking devices, and storage systems without needing a higher-rated UPS.

3. High Energy Efficiency

The system achieves up to 96% efficiency in double-conversion mode and up to 99% in ECO mode. High efficiency reduces energy consumption, lowers electricity bills, and minimizes heat generation, which also helps reduce cooling requirements in data centers and server rooms.

4. Compact High-Density Design

The UPS is designed with a compact footprint and high power density, allowing it to deliver large power capacity while occupying minimal floor space. This makes it ideal for installations where space is limited, such as server rooms, telecom facilities, and small data centers.

5. Parallel Capability for Scalability and Redundancy

The system supports parallel operation with up to four UPS units. This allows organizations to either increase total power capacity as demand grows or create redundancy (N+1 configuration) to ensure continuous operation even if one UPS fails.

6. Integrated Maintenance Bypass

The built-in maintenance bypass switch allows technicians to service or maintain the UPS without shutting down connected equipment. This ensures continuous power supply during maintenance, reducing downtime for critical systems.

7. Advanced Battery Management

The UPS includes intelligent battery management that optimizes battery charging and discharging cycles. It uses temperature-compensated charging and monitoring to extend battery life, improve reliability, and ensure batteries are always ready during a power outage.

8. High Input Power Factor and Low Harmonic Distortion

The UPS provides a high input power factor (≥0.99) and low input harmonic distortion (≤3%), which reduces stress on upstream electrical infrastructure such as generators and transformers. This results in more efficient power distribution and improved electrical system stability.

9. Flexible Monitoring and Communication Options

The UPS supports communication interfaces such as SNMP, Modbus, and dry contacts, allowing integration with network monitoring systems and building management systems. This enables remote monitoring, alerts, and proactive maintenance.

10. Reliable Power Protection for Critical Loads

The UPS is engineered to protect mission-critical equipment including servers, storage systems, telecom devices, medical equipment, and industrial control systems from outages and power disturbances, ensuring continuous operation and preventing costly downtime.
