Modern server rooms house critical IT infrastructure, including servers, networking equipment, and supporting power and cooling systems. Depending on operational scale, a server room may contain anywhere from a few racks to hundreds of servers, all securely organized within rack enclosures for efficiency, safety, and ease of maintenance. These servers typically operate without local displays or input devices and are monitored and managed remotely from centralized control locations.

As computing demands continue to grow, server room power requirements become increasingly complex and critical. To maintain uninterrupted operation and protect sensitive equipment from power disturbances, a reliable uninterruptible power supply (UPS) system is essential. For medium to large server room applications, a double conversion true online UPS in the 10–300 kVA range is the preferred solution, delivering continuous, clean power, zero transfer time, and maximum protection for mission-critical IT environments.

Feature

In a true online double-conversion UPS, the inverter operates continuously to deliver clean, stable, and reliable power at all times. This design ensures complete isolation of the connected load from utility power disturbances, making it ideal for applications where uninterrupted uptime is critical.

By converting incoming AC power to DC through a rectifier and then back to AC via the inverter, the UPS provides precise voltage regulation, stable output frequency, and effective protection against surges, sags, harmonics, and electrical noise. In the event of a mains power failure, the system seamlessly draws energy from the battery without any transfer delay, ensuring uninterrupted power delivery to critical equipment.

True Online Double Conversion

Provides continuous online power with zero transfer time. DSP technology ensures maximum reliability and stable output for critical equipment.

Galvanic Isolation Transformer Design

Built-in isolation transformer delivers true galvanic isolation, protecting sensitive loads from electrical disturbances.

Parallel Capability up to 4 Units

Supports parallel and redundant configuration to enhance overall system reliability and scalability.

Designed to Withstand All Load Types

Industrial-grade design suitable for all types of loads, ensuring consistent performance in varied operating conditions.

Multiple Communication Ports

Equipped with Modbus RS232/RS485, dry contacts, and expansion slots for convenient local and remote monitoring and management.
