Sentry Multistandard
SENTRY MULTISTANDARD provides
maximum protection for critical data
processing networks and security
applications, thanks to its advanced
design, selectable operating modes and
communications capabilities. Operating
modes include: On-line, Economy,
Smart-Active, Standby/Off and Voltage
Stabilisation. Standard communications
features include a front panel LCD with
128 potential messages, RS232
interfaces, EPO input, communications
interface slot and Watch&Save 3000
management software.
The SENTRY MULTISTANDARD series
includes 60-80 kVA three-phase models,
and uses on-line double conversion
technology (VFI). The load is powered
continuously by the inverter with a
filtered, stabilised and regulated sinewave
supply. The input and output filters
considerably increase the immunity of the
load to mains disturbances and surges,
even on bypass.
LOW POWER CONSUMPTION
• On-line Mode: up to 92% efficiency
can be achieved due to the use of
IGBT technology, increasing to 98% in
one of the other operating modes
• Economy Mode: uses Line Interactive
(VI) technology to power less critical
loads from the mains supply for certain
periods
• Smart Active Mode: if the mains supply
is out of range, the UPS will power the
load from the inverter as an On-line
UPS. When the mains supply returns
to within range again, the UPS will
monitor this for a certain period before
selecting Line Interactive operation.
