Online UPS(EA860 10-60KVA)

Detailed Product Description

Idea Application

Centralized server center, network control center, computing center

Features & Benefits

100% digital technology
Self-diagnosis, circuit control, parameters setting and program management are based on 3 high speed micro-controllers.
Applies high-tech components
DDC (Direct Digital Control), DSP (Digital Signal Processing), ASIC (Application Specific IC) and CPU are used in this system.
Super performance from IGBT
High speed on/off, operating on high voltage and large current, simple gate control circuits (voltage-controlled), high efficiency, and high stability.
Fully meets sharp load fluctuation from 0 to 100%
Completely meet the requirements of sharp load fluctuation without transferring to bypass, and maintain the output within tolerance.
Large screen LCD display
Users can conveniently operate the UPS according to the instructions and easily get UPS operating status at any time via large screen LCD.
Perfect protections
Built-in over/low-voltage, over-current, overload, and short circuit protections ensure lowest failure rate.
Low output voltage distortion
Owing to partial circulating current control, inverter could rapidly control impulse current from load change and surge. UPS can quickly respond to load change via feedback control.
Intelligent battery management
UPS will automatically charge and discharge the battery in float charging or boost charging mode according to the cycle set by the internal software, and automatically maintain the battery without manual operation, which prolongs the battery life.
