RS PRO is proud to introduce a series of Online Uninterruptible Power Supplies. These superb UPS units are designed to keep equipment such as computers safe when there is a reduction or loss in the primary power source. Our single phase online UPS devices are rack mount/standalone units that offer a medium power density, internal battery packs and have been tested and approved for reliability.

An uninterruptible power supply (UPS) is designed to give your computers, servers, server rooms, and data centres power in the case of any unexpected energy cut-off or in similar applications. These power supply devices contain a battery that guarantees power to your computer system for a certain period. These enable the user time to save the current task and shut down the software. Uninterruptable power supplies ensure mission-critical data loss can be prevented.

RS PRO online uninterruptible power supplies have been specifically designed for operation in low or poor power areas. These are true double-conversion enabled UPS that does not require a transfer switch as the primary power source passes through the batteries. They provide protection with stable power making them ideal for diverse environments. For full specifications please view the datasheets.

What's the difference between an offline and an online UPS?

An offline UPS supplies the AC mains power directly to the load under normal conditions and switches to the battery backup in the event of an outage. This means that there is a brief disruption of about 5ms (milliseconds) to the power supply. An online UPS supplies the AC electricity through a rectifier and inverter at all times, so there's no interruption in power.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards they’re only given the RS PRO seal of approval if we’re confident of their exceptional quality, which means you can be confident too.
