The best way to distribute uninterruptible power to several single phase rack cabinets is via a sub-distribution board. From this device, a single cable can be run under a raised access floor or via overhead cable trays to the server rack PDU. The cable connector can include a blue Commando style connector for the rack PDUs to connect to.
Single Phase UPS Systems
Our single phase UPS systems are designed to provide reliable power protection for server rooms and datacentre applications. Configured with a 1 phase input (1/1) or a 3 phase input (3/1), these systems ensure seamless operation. Whether you need a desktop, tower, or 19-inch rackmount unit, our UPS 1 phase options have you covered. For enhanced performance, we offer single conversion UPS systems and a range of accessories, including SNMP cards, UPS maintenance bypass switches, and extended runtime battery packs for longer backup times.

On-line Double Conversion UPS
The most commonly used power solution in a server room is an on-line double conversion UPS. This is because from a business continuity plan point of view, a on-line UPS includes an automatic bypass and will safely fails to mains power if there is an overload or internal fault. The UPS inverter is also running continuously to provide a digitally generated sinewave output. The next level power solution is a line interactive UPS which may have a sinewave or square-wave output on inverter and a built-in automatic voltage regulation (AVR). Basic UPS protection can be provided for IT peripherals and small loads using a standby / off-line uninterruptible power supply.
Single Phase Power Backup
For longer runtime critical power UPS installations battery extension packs may be an option or the UPS power supply can be installed with a backup power generator.
UK Single Phase Power
The UK single phase power supply is 230Vac 50Hz. To work out the UPS size multiply the Amps required by 230 to give a VA or kVA 1phase phase ups system size.
