Functions and Characteristics
•
Advanced IGBT modules are used in our UPS, with electronics that will work for more than
300,000 hours.
•
Digital Control Technology with high efficiency algorithm delivers a most reliable controller
design used to optimize the output parameters of the UPS.
•
The UPS performs a Self-Diagnostic Test before starting, enabling the UPS to detect and correct
any potential problems prior to powering up the load.
•
Double Conversion On-Line Topology makes the output of the UPS a pure sine wave with
consistent frequency and voltage regulation, low noise, and no interruption in power to the load
when utility power is lost.
•
Zero Transfer Time when the utility power fails or returns.
•
The UPS has a Bypass Function that allows for the load to be transferred to a bypass mode
when a UPS fault occurs. No interruption in power occurs to the load and an alarm will alert to
this occurrence. This feature also allows for configuring the UPS to support fully rated loads of
switching power supplies, as the bypass circuit can handle the start up.
•
Advanced Voltage Compensation Technology allows the input voltage range to be 115VAC to
295VAC, reducing battery usage and enhancing UPS response during utility power fluctuations.
•
Advanced Wide Input Frequency Technology enables the UPS to perform from 45 to 55 Hz
when 50Hz output is selected, or 55 to 65 Hz when 60Hz output is selected. All of this means
that the UPS is very compatible with single-phase generator operation.
•
Advanced Power Factor Correction (PFC) Technology on the input of the UPS makes the input
power factor more than 0.98, increasing power efficiency, removing harmonic noise, and lowers
the UPS operational cost.
•
Auto Start on Battery allows the UPS to start in battery mode when utility power is not
available.
•
Rack-Tower Conversion LCD means that the display can be read in Rack or Tower configurations
by only pressing a button – the display electronically rotates to provide the detailed information
in an easy-to-read manner.
•
ECO Function can help to save electricity by allowing the UPS to operate in a line-interactive
mode. The load is supplied with utility power directly while the inverter is in a standby mode
until needed.
