2. Introduction
2.1 General Characteristics
True double conversion online technology provides uninterrupted output to your critical device with
stable, regulated, transient-free, pure sine wave AC power.
• High-efficiency pulse-width modulation (PWM) sine-wave topology yields excellent overall
performance. The output is capable of handling high crest factor and high inrush current loads.
• User-friendly plug and play design allows hassle-free installation. All units up to 3kVA are supplied
with input cables and output sockets as standard.
• Built-in maintenance-free sealed-type battery minimizes after-sales service.
• Automatic overload protection switches the output from inverter mode to bypass mode if the load
increases to 105 to 120% of full load for 30 seconds and automatically enables inverter mode when
the overload condition is removed.
• 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.
• The USB / RS232 interface provides convenient plug and play with other IT products powered by the
UPS.
2.2 Special Features
• High frequency transformer-less technology with a rack/tower convertible enclosure facilitates
integration of the UPS even in difficult environments with space constraints.
• 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
capability by providing the flexibility for easy remote control and monitoring.
• Wide input voltage tolerance from 60V to 144V (120V version) or 120V to 288V (230V version) allows
under-voltage or over-voltage correction without unnecessary battery drain which helps to extend
the battery life span.
• DC-start function ensures start-up of the UPS even during power outages.
• Revolutionary battery management circuit analyzes battery discharging status to adjust the battery
cut-off point and extend the batteries’ life span.
• Active Power Factor Correction (PFC) control function constantly maintains the UPS Input Power
Factor (PF) at > 0.99 for energy efficiency.
• Selectable Bypass input voltage tolerance (Sensitivity low/high) prevents the supply of under or over
voltage to the loads in Bypass mode. The selectable Voltage ranges are:
• Sensitivity Low: 90/ 180 to 130/ 260V
• Sensitivity High: 97/ 194 to 130/ 260V
• Large number of selectable output voltages (100/ 110/ 115/ 120/ 127 V or 200/ 208 /220 /230 /240 V)
meet the requirements of various voltage systems.
• The UPS complies with various stringent international standards for Electromagnetic Interference &
Compatability (EMI & EMC).
