PowerShield Centurion 3000VA Tower overview
The Centurion Tower is PowerShield's true online double-conversion tower UPS for critical equipment. The PSCE3000 is rated 3000 VA / 2700 W (output power factor 0.9) and outputs a pure sine wave with zero transfer time from AC mode to battery mode. PowerShield designed it for critical power applications, remote locations more than 30 km from the city grid, light to heavy industrial environments, sites with generators and applications that need remote connectivity.
Outlets: 15 A IEC C19 x 1 and Australian sockets x 4. It runs on 6 internal 12 V 9 Ah batteries with a typical recharge of 4 hours to 90% capacity. PowerShield notes 3kVA models need a 16 A (15 amp) wall socket rather than a standard 10 amp outlet.
Built for unstable power
A wide input voltage window (110–300 VAC ±5% at 50% load; 160–300 VAC ±5% at 100% load), input power factor correction of 0.99 or better, generator compatibility and a 50/60 Hz frequency converter mode suit regional and industrial sites. ECO mode reaches 98% efficiency when mains quality allows.
Management
USB and RS-232 are standard with HID support for Windows, Apple, Linux and NAS devices and the free PowerShield NetGuard software. The intelligent slot takes the PSSNMPV4 SNMP card, the PSAS400 relay card or a Modbus card, and programmable outlets plus EPO are built in.
Extending runtime
Backup time on the Centurion Tower is extended by plugging in additional battery banks. PowerShield's datasheet lists PSCEBB12 and the PSCEBB18CH (with its own 4 A charger) for 2 and 3 kVA models; see the runtime table below. These battery banks are available on request from ARC IP Networks. The Centurion Tower range runs from 1000 VA to 10000 VA.

Other PowerShield published runtime figures
PowerShield publishes these backup times for the PSCE3000 on its own and with Centurion Tower battery banks added. To size a UPS, PowerShield suggests adding the watts of the equipment to protect and dividing by 0.7 to get the VA rating the UPS must exceed.
