Standby UPS Systems
Ultimate cost-effective battery backup for small loads
Minuteman's EnSpire Series standby UPS systems provide a low-cost, high performance solution for protecting small load computers, network equipment, and security devices from damaging power problems.
Minuteman Standby UPS Products
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
Minuteman Line Interactive UPS Products
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
Minuteman True On-line UPS Products
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
Minuteman's range of 3-phase UPS systems provide efficient for large facility backup. Benefits over single phase On-line backup include:
- Increased system efficiency (up to 94%) for lower utility costs
- A centralized backup solution for widespread systems
- Ultimate power quality for large load applications
Minuteman 3-phase UPS Products
How 3-phase UPSs Work
