Product Introduction
General Characteristics
True on-line technology continuously supplies your critical device with stable, regulated, transient-free, pure-sine-
wave AC power. A High-efficiency PWM sine-wave topology yields excellent overall performance.
The high crest factor of the inverter handles all high in-rush current loads without the need to upgrade the power
rating.
To protect the unit from overloading, 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 is cleared.
Should the output become short-circuited the UPS puts the system in stand-by mode, provides visible and audible
alarms, and cuts the output supply automatically until the short circuit situation is resolved manually.
Our High Frequency Transformer-less technology and enclosure enables the UPS to be integrated into even the
most difficult environments with space constraints.
This UPS is equipped with fully digital control logic for greater functionality and enhanced power protection. Digital
signal processing (DSP) also provides the UPS with powerful communication capability, which simplifies remote
control and monitoring.

Industry Leading A/C input voltage range of 55-150 V allows under-voltage or over-voltage correction without
unnecessary battery drain and helps extend battery life.
A Cold DC-start function ensures the start-up of the UPS even during power outages.
Our Active Power Factor Correction control function constantly maintains the UPS input power factor at > 0.98 for
superb energy efficiency.
A 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 120 V the Bypass Sensitivity Low range is 120 V ±15%, i.e., 102-138 VAC.
The UPS provides numerous configurable output voltages to match a wide range of system voltages.
The UPS is designed to comply with various stringent international standards for electromagnetic interference
compatibility (EMC) as well as FCC classification.
