Pulsar Esprit
3 –13.5 kVA
High Availability UPS for Internet Servers
MGE UPS SYSTEMS all new Pulsar Esprit has been specifically
designed to meet the needs of Internet Service Providers & Application
Service Providers. Esprit provides total power availability with redundant
UPSs for the price of a regular, single UPS. This redundant combination,
called Power Cluster, has been pioneered exclusively by MGE.
Pulsar Esprit has been designed with the Internet in mind:
For the first time, it is possible to remotely monitor an UPS using
XML tags to perform automatic actions. This breakthrough technology
is the result of MGE's heavy investment in research and development.
They provide ISPs with the best combination of power availability
and cost. With the revolutionary Esprit Power Cluster, MGE brings
affordable, total power availability to smaller ISPs and mid-size
businesses with 3 to 15 servers.

Configuration Comments
Single point of failure Traditional redundant UPSs are paralleled at their outputs and provide
a worrisome single point of failure.
Redundant power paths With Esprit, power sharing is achieved within each server on the DC bus.
Redundant power sources Input power connections of servers will be connected to 2 (or 3) different Esprit
modules, providing 2 (or 3) different sources, eliminating a single point of failure.
Esprit, for the first time, provides MGE’s advanced engineering & design significantly reduces the component
total power availability combined count for high availability and reliability at an affordable price. Traditional N+1
with maximum reliability UPS redundancy can provide power availability at the expense of reliability with
multiple sub-assemblies that increase the chance of costly failures.
Power redundancy for servers with multiple power supplies
Most servers provide multiple power supplies for N+1 redundancy. To maintain high availability of the system when considering
power, a redundant configuration as offered with the Esprit Power Cluster is better than traditional N+1 redundant UPSs:

Example of 5 PC servers with 3 redundant power supplies:
◗ Select a 4.5 kVA Esprit Power Cluster
◗ Connect the first power supply of each server to the Esprit
◗ Connect the second power supply of each server to the Esprit
◗ Connect the third power supply of each server to the Esprit
◗ Connect each Esprit to a separate wall outlet.
