How Standby UPSs Work

The most basic UPS technology, Standby UPSs provide filtering and protection from spikes and surges. The battery within the unit is utilized to normalize low voltage situations, high voltage events, and blackout conditions. If one of these conditions occurs, the inverter automatically switches to battery mode to condition the power.

Line Interactive UPS Systems

Cost-effective protection for critical devices

Minuteman's Line Interactive UPSs utilize an Automatic Voltage Regulator (AVR) to normalize power problems. Added benefits over Standby UPSs include:

  • Longer battery life spans
  • Higher efficiency (lower engergy cost)
  • Longer runtimes during outage situations
  • True sine wave output on select models

How Line Interactive UPSs Work

The "Better" level of UPS technology, Line Interactive UPSs provide filtering and protection from spikes and surges by utilizing an automatic voltage regulator. A Line Interactive UPS preserves battery life because it is not constantly switching to battery mode in areas plagued with brownouts.

In a blackout situation, all Minuteman line-interactive UPSs switch to battery mode in less than 4 milliseconds. Additionally, line-interactive units provide protection from spikes and surges, plus RFI and EMI filtering.

True On-line UPS Systems

The best quality protection for critical and sensitive devices

Minuteman true On-line battery backup systems provide the highest quality of power protection for critical, large load devices. Added benefits over Line Interactive units include:

  • Zero transfer time to battery when utility power fails
  • Complete protection during changeover to auxiliary generators
  • The highest efficiency levels of all UPS types
  • Large load and extreme runtime capability

How On-line UPSs Work

The "Best" level of UPS technology, On-line battery backup systems provide the highest quality of power protection by incorporating double-conversion technlogy, whereby power coming in to the UPS is converted from AC to DC. Power is then conditioned and converted back to AC at the output of the UPS.

There is no transfer or switching time since power actually runs through the battery system at all times. By isolating the input from the output, on-line UPSs provide true sinewave power to attached equipment that is clean and free of any power anomalies, making them an ideal solution for sensitive information systems, network equipment, as well as protection from power anomalies which can be present during changeover to generator power.

3-phase UPS Systems

Efficient, high quality protection solutions for data centers and facilities

GE's Digital Energy 3-phase UPS systems provide efficient for large facility backup. Benefits over single phase On-line backup include:

  • Increased efficiency for lower utility costs
  • Redundancy (Redundant Parallel Architecture or RPA) for fail-safe protection
  • Ultimate power quality for large load applications
