Introduction
2.1. General Characteristics
True online technology continuously supplies your critical device with a stable,
regulated, transient-free pure sine wave AC Power.
1. High-efficiency PWM sine-wave topology yields an 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.
2. 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.
3. Built-in Maintenance-free sealed-type battery minimises the need for
frequent after-sales service.
4. To protect the unit from overloading, the UPS will automatically switch
to bypass mode in 30 seconds if loading is at 105%~ 120% of rated
capacity. It will automatically switch back to inverter mode once
overload condition ceases.
5. Should the output becomes short-circuited, the UPS puts the system on
stand-by mode, provide visual & audible alarm, and cuts the output
supply automatically till the short circuit situation is resolved manually.

2.2. Special Features
1. High Frequency Transformer-less technology with rack/tower convertible
enclosure enables the UPS for integration even in the most difficult of
environment with space constraints.
2. This UPS is equipped with fully digitalized control logic for greater
functionality and enhanced high level of power protection. Digital signal
processing (DSP) also provides the UPS with powerful communication
capability, which enhances the flexibility for easy remote control and
monitoring
3. Wide input voltage tolerance from 60V ~ 144V (110V version) or
120V~288V (220V version) allows under-voltage or over-voltage
correction without unnecessary battery drain and helps extend the battery
life span.
4. DC-start function ensures the start-up of UPS even during power outages.
5. Revolutionary battery management circuit analyzes battery discharging
status to adjust battery cut-off point and extend the batteries’ life span
.
6. Active Power Factor Correction (PFC) control function constantly
maintains the UPS Input Power Factor (PF) at > 0.99 for superb energy
efficiency.
7. Selectable Bypass input voltage tolerance (Sensitivity low/high) to prevent
under or over voltage being supply to the loads at Bypass mode. The
selectable Voltage ranges are (i) Sensitivity Low
：
90/180~130/260V & (ii)
Sensitivity High
：
97/194~130/260V.
8. Vast Selectable Output Voltages (100/110/115/120/127V or
200/208/220/230/240) to meet various voltage systems.
9. The UPS is designed to comply with various stringent international
standards for Electromagnetic Interference & protection (EMC).
