2.1. General Characteristics
2.1.1. True online architecture continuously supplies your critical device with stable, regulated, transient-free,
pure-sine-wave AC power.
2.1.2. High efficiency PWM sine-wave topology yields excellent overall performance. The high crest factor of the
inverter handles all high-inrush current loads without a need to upgrade the power rating.
2.1.3. The multi-functional LCD/LED panel displays various states of the UPS. The LED display shows the UPS
working status, utility status and abnormal status. The LCD display shows input/output voltage, frequency,
load status, inner cabinet temperature and abnormal phenomena.
2.1.4. The unit automatically switches to Bypass mode after 5 minutes to protect it from overheating, if loading is at
111~130% of rating. In case of overloading at 131~150% of rating, it switches to Bypass mode after 1 minute.
In case of overloading at 151% of rating, it switches to Bypass mode immediately. It will automatically switch
back to Inverter mode once the overload condition ceases for 5-10 kVA.
2.1.5. The UPS will automatically switch to Bypass mode in 30 seconds if loading is at 105% of rated capacity. It will
automatically switch back to Inverter mode once the overload condition ceases for 1-3 kVA.
2.1.6. The UPS cuts the output automatically when the output gets short-circuited. The short-circuit situation needs
to be removed manually.
2.1.7. When the unit gets overheated, the internal thermal switch detects the heat and switches to Bypass mode
and vice versa.
2.1.8. The fully digitalized control circuit built into the UPS allows the upgrading of its functionality as well as
reaching a high-level of protection of the UPS. Powerful communication capability enhances its ability for
remote control and monitoring.
2.1.9. Maintenance-free, sealed batteries minimize after-sales service.
2.1.10. The maintenance Bypass switch provides an easy and safe troubleshooting or maintenance function when the
utility is normal.
2.1.11. The unit provides four different working modes (Normal, ECO, CF50 and CF60) to be used in a wide variety
of applications.
2.1.12. The DC-start function ensures the UPS starts up even in power outage.
2.1.13. A revolutionary battery management circuit analyzes the battery discharging status to adjust its cut-off point
and extend the battery life.
2.1.14. The intelligent, temperature-controlled fan not only extends the life of the fan but also reduces the annoying
noise of sudden fan spin. This helps keep your office quiet and comfortable.
2.1.15. When the UPS malfunctions you can read the possible reason from the LCD screen directly, which reduces
unnecessary repairs.
2.1.16. When the UPS is operated in CF50 or CF60 mode; the recommended load connected shall be 75% of rated
capacity if the input voltage is 160-300 VAC, 50% of rated capacity if the input voltage is 140-160 VAC and 25%
of rated capacity if the input voltage is 110-140 VAC.
2.1.17. Our selectable Bypass input voltage tolerance (sensitivity low/high) prevents under- or over-voltage being
supplied to the loads in Bypass mode. The selectable voltage ranges are (i) Bypass Sensitivity Low: many
selectable output voltages ±15% and (ii) Bypass Sensitivity High: many selectable output voltages ±10%.
For example, if the output voltage setting is 230 V, the Bypass Sensitivity Low range is 230 V ±15%, i.e.,
195.5-264.5 VAC
