EA990 G5 10kVA-30kVA (3:3) Transformer Tower UPS
The EA990 G5 Tower UPS is a dependable power conversion and protection device designed for medium- to large-scale power demands. Its design philosophy ensures that in the event of grid faults or power outages, user equipment and systems can continue normal operation, ensuring business continuity.
Product Description
The EA990 G5 is a high-performance transformer designed to meet power requirements ranging from 10 kVA to 30 kVA, with a 3:3 input-output transformer ratio. This transformer serves as a key component of the Tower UPS (Uninterruptible Power Supply) system, aiming to provide reliable power protection.
Features
- Dual input design, supporting independent bypass
- Advanced digital and parallel technology, providing higher reliability than a single system
- Fan speed varies intelligently with load, reducing noise and extending its service life.
- Conformal coating technology to make UPS operate in harsh environments for a long time
- Digitally controlled charger (max. 10A)
- Ability to switch on the UPS by battery in the absence of mains power (cold start)
- Zero switching time for UPS power supply mode when the mains power is unstable, ensuring the output is uninterrupted.
- Linear derating in low-voltage input, reducing battery discharging times, and extending the service life of batteries
Application
- IDC data exchange room
- ISP,Computer Room
- Bank/Bond Clearing Center
- Industrial Process Control Applications
- Precision instruments and equipment
