2. Product 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 han-
dles 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
3kVAva are supplied with input cables and
output sockets as standard.
3. Built-in Maintenance-free sealed-type bat-
tery 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 over-
load 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
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.
1. This UPS is equipped with fully digitalized
control logic for greater functionality and
enhanced high level of power protection.
Digital signal processing (DSP) also pro-
vides the UPS with powerful communica-
tion capability, which enhances the flexibil-
ity for easy remote control and monitoring
2. Wide
input
voltage
tolerance
from
184V~288V allows under-voltage or over-
voltage correction without unnecessary
battery drain and helps extend the battery
life span.
3. DC-start function ensures the start-up of
UPS even during power outages.
4. Revolutionary battery management circuit
analyzes battery discharging status to ad-
just battery cut-off point and extend the
batteries’ life span.
5. Active Power Factor Correction (PFC)
control function constantly maintains the
UPS Input Power Factor (PF) at > 0.99 for
superb energy efficiency.
6. 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 : 184~260V
& (ii) Sensitivity High : 194~260V.
7. Fast

tems.
8. The UPS is designed to comply with vari-
ous stringent international standards for
Electromagnetic Interference & protection
(EMC).
9. A use different from that described here is
considered to be an improper use. Rittal
cannot accept any liability for damage re-
sulting from the improper use or the non-
observance of this guide. The guides for
the used accessories may apply.
