Minuteman UPS Battery Back up UPS

Minuteman UPS systems prevent brown outs and electrical outages.  If you are not sure what UPS to purchase please use our UPS SIZING GUIDE to choose the correct system.  If you need help configuring your system please call us at 800-822-2604.

UPS Systems come in 3 basic configurations.  Stand-by, line interactive, and double conversion.

Whats the difference?

A stand-by UPS is the lowest priced type of battery backup protection available. During any type of power fluctuation, a standby UPS switches to battery mode to provide clean power to attached devices. Standby UPSs do provide total protection from any type of power problem and are a good choice where there are budget constraints.

Line interactive UPSs also provide complete protection, but manage incoming power differently than a stand-by UPS. The most common power problems are small variations in incoming AC voltage, such as brownouts or sags, as well as over-voltages, such as surges and spikes. This type of UPS employs an automatic voltage regulator that corrects these anomalies without accessing battery power, thus putting less strain on the battery and extending its life.

A true online double conversion UPS completely re-generates the incoming AC power to provide the best type of power protection available. This is accomplished by an internal inverter converting incoming power from AC to DC, and at the output, the DC signal is then converted back to AC. Through this double conversion process, the UPS creates an “electrical firewall” to fully isolate attached equipment from any type of power problem.
