Uninterruptible Power Supplies (UPS) play a vital role in protecting critical installations by ensuring continuous power in the event of a power outage or grid disturbance. They are widely used in data centers, IT infrastructures, healthcare facilities, security systems, and industrial applications.
The electronic components within UPS systems generate significant heat, which must be efficiently dissipated to ensure optimal performance, reliability, and long service life.
ETRI compact axial fans are designed to cool UPS cabinets and electrical enclosures effectively. With their high airflow, compact design, and proven reliability, they help maintain optimal operating temperatures and ensure the continuous operation of mission-critical equipment.
ETRI compact DC axial fans provide efficient cooling for electronic equipment while minimizing installation space. Thanks to their high airflow and proven reliability, they are ideally suited for electrical enclosures, electronic racks, Uninterruptible Power Supplies (UPS), industrial control systems, data centers, and other applications requiring high-performance thermal management.

Thermal Management for UPS and Uninterruptible Power Supply Systems
Uninterruptible Power Supplies (UPS) play a vital role in ensuring business continuity for critical infrastructures such as hospitals, data centers, telecommunications networks, and industrial facilities. By continuously converting and regulating electrical power, these systems generate significant heat that must be efficiently dissipated to prevent failures and maximize equipment lifespan. ETRI designs compact, robust, and intelligent ventilation solutions specifically engineered for UPS and power electronics applications.
- Key Thermal Challenges in UPS Systems
- Power electronics cooling: Active semiconductor components—including IGBTs, power diodes, and rectifier bridges—generate substantial heat during operation. Efficient forced-air cooling is essential to maintain safe junction temperatures and ensure long-term reliability.
- Backup battery protection: The service life of lead-acid and lithium-ion batteries is highly dependent on operating temperature. Excessive heat accelerates battery aging and significantly reduces backup capacity. ETRI fans maintain a stable and uniform temperature, helping to extend battery life.
- ETRI Fan Technologies for UPS Applications
- Operational safety and diagnostics: Available with tachometer outputs for fan speed monitoring and locked-rotor alarm signals, enabling predictive maintenance and preventing thermal runaway.
- Precise speed control: PWM and EC speed control technologies dynamically adjust airflow according to UPS load conditions, reducing fan power consumption and lowering noise levels.
- High operational reliability: Premium ball-bearing systems provide high MTBF (Mean Time Between Failures) for continuous 24/7 operation in mission-critical environments.
- Compact Integration for Modern UPS Systems
- Ultra-compact axial fans: Standard AC and DC form factors allow easy integration into rack-mounted modular UPS systems and power cabinets.
- Centrifugal blowers: Designed to overcome the high static pressure generated by densely populated power electronics cabinets, ensuring effective cooling even in compact, high-power UPS installations.
