Power is pleased to announce its first battery-less Uninterruptible
Power System. It is a state-of-the-art, double-conversion
“UPS” that uses Supercapacitor technology
for energy storage instead of conventional batteries. |

 Description |
|
| |
|
|
The
system is designed to provide short term backup to sensitive
loads in applications that either need to ride-through
voltage sags and momentary power outages or simply bridge
the startup of a generator.
Since most power interruptions (87%) last no more than
1 second according to the Electric Power research Institute,
there is seldom a need for long-term storage technology
such as batteries. It is targeted specifically at applications
that are sensitive to power disturbances that last from
a few cycles to around one minute.
This most ‘Green’ of all UPS technologies
offers numerous advantages over conventional UPS’s
and other energy storage technologies such as flywheels
and fuel cells. There is no battery replacement, system
maintenance, hazard waste disposal or component recycling.
The system consists of 2 parts – the UPS Electronics
module and the Energy Storage module.
The Electronics module is configured as a true-online
double conversion UPS. This topology is ideal for the
most critical applications where the best level of power
protection is required. Connected equipment is not only
immune to the slightest power fluctuations, but also other
power anomalies such as spikes, surges, sags, swells,
harmonics and frequency variations.
The unit features a wide input voltage tolerance, tight
output voltage regulation and very low harmonic distortion.
Twin microprocessors aid redundancy and an automatic bypass
switch ensures that power to the load is not interrupted
in the event of a system fault.
The Energy Storage module is a self contained unit that
consists of the Supercapacitors and their associated electronics.
The module can be charged independently of the system.
The first model in the lineup is a 3000VA, 2100 Watt model
at either 120V or 230V and a backup time of 15 seconds
at full load and 45 seconds at half load. Recharge time
is approximately 2 minutes but can be reduced with a suitable
AC source. Other run times are available using additional
energy storage modules or different Supercapacitor combinations.
The system features a user-friendly, multifunction LCD
control panel that indicates the status of the system
and allows the user to make parameter adjustments. Communication
options include power-monitoring & system management
software and SNMP capability.
One of the key applications is in healthcare where critical
loads in this environment need support during the startup
of an emergency generator. Another primary application
is in the industrial automation market where relatively
short holdup times will allow a process to continue uninterrupted.
An example of this is the semiconductor fabrication industry
where manufacturing equipment is required to meet semi
F47 ride-through standards.
