Product Introduction
2.1.
General Characteristics
2.1.1.
Pure online UPS architecture to provide connected equipment with
pure sine wave AC power that is stable, continuous and has a fixed
voltage.
2.1.2.
High-efficiency PWM sinusoidal modulation technology is used to
improve the UPS efficiency and stability.
2.1.3.
Overload Protection: Automatic overload protection that will run for 60
minutes when load exceeds 110%. Overload protection lasts 10
minutes when load exceeds 125% and 1 minute when load exceeds
150%. When overload protection ends, UPS will automatically switch to
the alternative power supply circuit. When the situation ends the UPS
automatically restores the inverter. If overloading forces the UPS to
switch to the alternative circuit more than 3 times, the switching
mechanism is locked on the 3rd time to keep the UPS on the alternative
circuit.
2.1.4.
Short Circuit Protection: When there is short circuit in the output, the
UPS will automatically cut off, sound an alarm and retain the error so
the user can troubleshoot the problem. The automatic cut-off prevents
electrocution and fire hazards during the troubleshooting process.

Special Features
2.2.1.
Digital Signal Processor (DSP) is used to monitor the UPS operation to
improve its function and protection. Monitoring is enabled through the
signal port.
2.2.2.
There are three user-selectable operating modes: VFI mode, ECO
mode, and CONVERTER mode.
2.2.3.
The cold-start module allows the UPS to be started from the battery
side when emergency power is needed.
2.2.4.
PFC Control is used to maintain the input power factor correction at
PF>=0.99 and reduce the load on the grid.
2.2.5.
Programmable output voltage devices allow the user to select the
voltage appropriate to the current environment.
2.2.6.
Touch control interface allows data to be displayed in real-time. The
