Why is the
S4 theyour
most
reliable
critical power protection solution?
System Operation:
Tri-Layer Redundancy:
The Inverter plant receives 48 VDC from a
DC power plant/battery bank and converts
the output to precision regulated AC power
(user selectable voltage and frequency). In
the event that the DC is not available or out
of tolerance due to a discharged battery, or
the inverters are not able to maintain the
critical load, the system will automatically
transfer via the static transfer switch and
disconnect from the DC source. The static
transfer switch (standard) will make a seamless, uninterrupted transfer from the critical
load to an alternate AC power source where
the inverter power was synchronized to
utility power or another protected AC
source. The MTBF of the S4 N+1 on-line
mode with a backup source present is
greater than 99.9999%.
Three independent layers of redundancy
contribute to the S4’s reliability
starting with the N+1 inverter assemblies,
dual independent microcontrollers
and integrated static transfer switch for a
final layer of protection.

Telecom Grade Filtering:
Since the S4 is connected to large telecom
battery plants and shared by other critical
equipment, it is equipped with a high grade
noise filter system, limiting ripple current
on the battery to well under required levels,
as well as ensuring that radiated and
conducted EMI are kept to safe levels.

Regulatory Compliance ~ built to meet industry standards
The S4 inverter is designed to meet the
stringent regulatory qualifications demanded by telecommunications facilities. As
well as meeting all major safety standards,
the S4 inverter is one of the only inverters
designed to meet Network Equipment
Building System (NEBS) standards~
the industry benchmark
for product quality and reliability.

Power-Invert™ S4 Inverter Plant Accessories
Options to meet your specific requirements
The S4 is available with the following optional accessories, all of which can be factory
installed on an open frame relay rack, providing a ready to install inverter system.
Maintenance Bypass:
AC Distribution Panel
Safely and seamlessly transfers the output to an alternate AC source (utility power
or protected AC power from another inverter or UPS system) allowing the inverter
to be shutdown or removed without interrupting power to the critical loads. The
Maintenance Bypass assembly is factory wired to the inverter module when
ordered as a system.
AC Distribution Panel:
The AC distribution panel accommodates 20 single pole breakers and is available
in 120 and 240 VAC versions. 10 x two pole breakers can be used if distribution
alarm monitoring is required.
Maintenance Bypass Cabinet
Web Based Monitoring:
The Falcon monitoring system (1.75” high rack mounted) provides inverter, maintenance bypass and AC distribution status and alarms over a closed network or via the
Internet serving up web pages that can be viewed with a standard browser or via
SNMP or dial up access. Accessories include environmental monitoring modules and
auxiliary inputs to monitor other devices such as leak detection systems, room
security or any other dry contact status points.
S4 Fortress Inverters
Open Frame Relay Rack:
All components can be mounted on an industry standard open frame relay rack with
the entire inverter plant certified for zone 4 seismic installations.
Conduit Junction Boxes: (optional when maintenance bypass is not used)
Larger inverter modules such as the 14 kVA through 21 kVA require substantial
cable gauges. The conduit junction box is factory mounted to the back of the inverter
module, easing conduit landing requirements and simplifying installation of rear
mounted cable entry systems.
Rack
Inverter Systems
Inverter systems include inverter(s), receiver cabinet, static switch and single controller module (redundant controller module optional).
N+1 redundant power rating indicates that a single inverter module can go off-line with existing inverters maintaining the critical load.
(Rack mount bracket kit is optional.)
