EA990 G4 40kVA-200kVA (3:3) Rack Mount UPS
The EA990 G4 is a high-performance online transformer-based Uninterruptible Power Supply (UPS) designed to address power fluctuations and outages. The UPS series has a rated capacity ranging from 40 kilovolt-amperes (kVA) to 200 kVA, employing a 3:3 input-output configuration to provide users with stable and reliable power protection. One of its key features is the utilization of advanced online transformerless technology, ensuring efficient and reliable power conversion and transmission.
Product Description
The EA990 G4 UPS series represents an advanced online transformer-based UPS designed for critical applications requiring high-quality power protection, such as data centers, and industrial production. Unlike traditional transformer-based UPS systems, this series adopts transformerless technology, specifically the Online Transformerless UPS. This means that it does not rely on conventional transformers during power transmission, thereby improving efficiency, reducing energy consumption, and minimizing size and weight.
Features
- Flexible battery configuration setting, selectable battery numbers: 30~ 44 pcs
- Digitally controlled charger (Max. 48A)
- 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 uninterrupted output
- Settable delayed start time when mains power is restored
- 5-inch LCD color touch screen, friendly human and machine interface
- Powerful background software for parameter configuration and online upgrade
- Advanced multi-platform communication for UPS monitoring: RS232, USB, RS485, RJ45, dry contacts, SNMP card, Wi-Fi card, and GPRS card
- Intelligent battery management, automatic equalized and float charging control, charger dormancy control, improving the reliability of the charger, and extending the battery life
- Options and accessories: RS232, USB, RS485, RJ45, parallel, dry contacts, EPO, and battery temperature compensation interfaces are supplied; optional SNMP card, Wi-Fi card, GPRS card, battery temperature sensor, EMD detector, and SMS alarms
