2. Introduction
2.1 General Characteristics
• The UPS continuously supplies your critical device with stable, regulated, transient-free pure sine
wave AC power.
• High-efficiency 20 kHz pulse-width modulation (PWM) sine-wave topology yields an excellent overall
performance. The output is capable of handling high crest factor and high inrush current loads.
• A multi-functional LCD/LED panel displays the status of the UPS. The LED display shows the UPS
working status, utility power status, and abnormal UPS status. The LCD display shows the input/out-
put voltage, frequency, load status, inner cabinet temperature, and abnormal conditions.
• Automatic overload protection switches the output from inverter mode to bypass mode if the load
increases to between 105 and 120% of full load for 30 seconds and automatically enables inverter
mode when the overload condition is removed. If the load reaches 150% of the rated capacity, the
UPS switches to the bypass mode immediately.
• If the output is short-circuited, the UPS locks automatically, provides visual & audible alarms and
cuts the output supply until the short circuit situation is resolved.
• If the unit overheats, the internal thermal switch detects the temperature and switches to bypass
mode. It switches back to the inverter mode once the temperature drops to a predetermined value.
• This UPS is equipped with fully digitized control logic for greater functionality and an enhanced high
level of power protection. Digital signal processing (DSP) enhances the UPS communication capa-
bility by providing the flexibility for easy remote control and monitoring.
• A maintenance-free, sealed-type battery minimizes after-sales service.
• An optional maintenance bypass switch provides easy and safe troubleshooting or maintenance
when the utility power is normal.
• Four different working modes are provided that can be used for a variety of applications:
a. Normal (On-line mode)
b. ECO (Economic mode)
c. CF50 (50Hz Frequency Converter mode)
d. CF60 (60Hz Frequency Converter mode)
• When the UPS is operated in the CF50 or CF60 mode, the recommended load must be 75% of the
rated capacity if the input voltage is 176 to 280 VAC, and 50% of the rated capacity if the input volt-
age is 160 to 280 VAC.
• A DC-start function ensures that the UPS starts up during power outages.
• Revolutionary battery management circuit analyzes battery discharging status to adjust the battery
cut-off point and extend the batteries’ life span.
• An intelligent temperature-controlled fan extends the life of the fan, and also reduces annoying noise
caused by the sudden acceleration of the fan.
• If the UPS is out of order, a fault message will be displayed on the LCD screen.
