PowerShield Commander Tower 1100VA

The PowerShield Commander is a sophisticated pure sine wave, line interactive UPS. Besides providing Automatic Voltage Regulation (AVR) it also provides for a Pure Sine Wave output while in backup mode.

This UPS is a cost effective solution for protecting applications such as networking, telecom, security and motors to name a few.

SKU: PSCM1100 Categories: ,

Pure Sine Wave Output
• The Commander Tower provides a sine wave output, even when the UPS is running off of its batteries.
• The pure sine wave offers an economical solution to back up gates, cameras, computers, motors, telephone systems and other sensitive equipment.
Output Power Factor 0.9
• With an output power factor of 0.9 the Commander Tower is a high-density UPS that will provide higher performance and efficiency to critical applications.
Programmable Power Management
• Features a combination of both Australian and IEC outlets.
• With programmable power management outlets users can easily and independently control load segments. During power failure this feature enables users to extend battery time to mission-critical devices by shutting down noncritical devices in a timely manner.
Ultra Modern, Informative LCD
• Designed by Power Shield engineers this ultra modern LCD features extra large numeral displays and an informative mimic allowing users to view up to date information at a glance.
ECO Mode
• With built in advanced ECO mode this UPS will achieve an efficiency of up to 98% during normal mains operation. Using this option will allow for reduced ongoing running costs.
Smart AVR with Buck and Boost
• With a built in voltage regulator, the Commander Tower will maintain regulated nominal output without using battery power during brownouts and overvoltages.
Emergency Power Off Function (EPO)
• This feature can turn off and isolate the UPS in the event of fires or other emergencies.
Multiple Communication Available
• USB, RS-232 supports PowerShield NetGuard® software for Windows, Linux and Mac
• Intelligent slot for either PSSNMPV4, PSAS400, PSMbus
