2. Product Introduction
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. 20 kHz 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. To protect the unit from overloading, it automatically switches to bypass
mode in 160 seconds ~ 40ms if loading is at 105 ~150% of rating. In case
of overloading at 150% of rating, it switches to bypass mode immediately.
It will automatically switch back to inverter mode once the overload
condition ceases.
2.1.5. Should the output become short-circuited, the UPS cuts the output
automatically until the short-circuit situation is removed manually.
2.1.6. Should the unit become overheated, the internal thermal switch will detect
the heat and switch to bypass mode and vice versa.
2.1.7. The fully digitalized control circuit built into the UPS allows upgrading the
functionality of the UPS as well as reaching a high-level of protection of
the UPS. Powerful communication capability enhances its ability for
remote control and monitoring.
2.1.8. Maintenance-free, sealed batteries minimize after-sales service.
2.1.9. The maintenance bypass switch provides an easy and safe
troubleshooting or maintenance function when the utility is normal.
2.1.10. Providing four different working modes (Normal, ECO, CF50 and CF60) it
may be used in a wide variety of applications.
2.1.11. The DC-start function ensures the start-up of the UPS during power
outages.
7
2.1.12. A revolutionary battery management circuit analyzes battery discharging
status to adjust the battery cut-off point and extend battery life.
2.1.13. The intelligent, temperature-controlled fan may not only extend the life of
the fan but also reduce annoying noise because of sudden fan spin. This
helps keep your office quiet and comfortable.
2.1.14. When the UPS is out of order 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 176-
280 VAC and 50% of rated capacity if the input voltage is 160-280 VAC.

2.4. Communication Port
The communication port on the UPS provides for RS-232 communication
with the UPS software to remotely monitor the power and UPS status.
You may use optional interfaces cards for R2E (second RS-232), RSE (RS-
485), USE (USB), DCE (Dry Contact), and SNMP. However, the R2E card, RSE
card and USE card must not be used simultaneously.
The software bundled with the UPS is compatible with many operating
systems such as Windows 98, 2000, ME, NT and XP. For other applications such
as Novell NetWare, Unix, or Linux please contact your local distributor for a
proper solution.
When the optional interface cards are used together with the onboard RS-
232 port the EPO signals will get highest priority, then the SNMP/WEB card, then
the shutdown command at the DCE, R2E, RSE, and USE cards, and then finally
the onboard RS-232 port gets the lowest priority.
