Minuteman
UPS
Uninterruptible Power
Supply
Which type of UPS backup power
supply do you need?
Stand-By UPS
Applications: Small to large PCs, Phone Key Systems,
Workstations and Security Systems.
(Sometimes called
"off-line") With this type of power supply, power comes directly from the
A/C outlet until the voltage sags or the power fails. After the power sags
or fails, a battery powered inverter almost immediately turns on to
continue to supply you with power. Batteries are charged, as necessary,
when direct A/C power is available. Even while power is coming directly
from the A/C outlet, the UPS provides protection from voltage spikes and
surges. Standby units are the low cost solution in the UPS family.
Standy-By
UPSs provide surge and spike protection as well as battery
backup when utility power fails. Voltage regulation is handled using
internal batteries.
The MINUTEMAN MN Series is a stand-by UPS system.
Line-Interactive UPS
Applications: Small to large PCs, Key and PBX Systems,
Servers, Phone Systems, Networking Equipment, Rackmount Servers and
Workstations.
Just like the
standby units, line-interactive UPSs provide protection from spikes and
surges, as well as supplying auxiliary power if a voltage sag or a
blackout occurs. Unlike the standby units, line-interactive UPSs provide
automatic voltage boost when the power dips, without accessing the
batteries. This feature provides continuous lined conditioning, promotes
longer battery life, and eliminates electronic "noise" that can cause
minor application errors and loss of data.
Line-Interactive UPS systems provide full protection from surges and sags without
going to batteries thereby increasing battery life for blackout
conditions. The unit interacts with the utility line to regulate small
changes in voltage. Minor voltage fluctuations are raised or lowered by
the AVR function of the UPS.
MINUTEMAN MBK-E, PRO-E, SmartSine,
Enterprise, and XRT are all line-interactive.
Sinewave UPS with Limited Runtime/Sinewave UPS with Extended Runtime
Applications: Workstations, Servers, Internetworking,
Telecom Equipment, Phone Systems, Security Systems and any device that has
internal motors such as large printers or factory equipment.
This
type of system produces output power virtually identical to that of
utility power. It is ideal for protecting sensitive types of electronic
equipment or motors that require a true sinewave to operate properly.
MINUTEMAN SmartSine models provide a true sinewave output with a limited
amount of battery runtime. MINUTEMAN Enterprise and XRT models provide a
true sinewave output and offer extended runtime using external battery
packs.
MINUTEMAN SmartSine, Enterprise, and XRT are all line interactive
and sinewave UPS products.
True On-line/Extended Runtime UPS
Applications: Workstations, PBX Systems, Network Servers,
Internetworking, Telecom Equipment, Phone Systems, Security Systems and
Other Critical Devices.
On-line UPSs provide the
highest quality of power protection by using a double-conversion
technique. The UPS takes the incoming A/C power and recreates it by
converting the voltage to D/C, then conditioning the power to eliminate
noise, sags, or surges, and, finally, converting it back to A/C before it
exists the UPS. Since the power runs continuously through the inverter,
there is no transfer or switching time to battery mode in the event of a
blackout.
The MINUTEMAN MCP-E and MCP Series models are true on-line UPS products
that feature extended runtime options.
