Introduction
Features of this product
Thank you for purchasing Omron's Uninterruptible Power Supply (UPS).
The UPS protects computers and other devices from power failures, voltage variations,
instantaneous voltage drops, and surge voltage such as that caused by lightning (a phenomenon
in which extraordinary high voltage occurs instantaneously).
Under normal conditions, commercial power is converted to direct current, and then it is converted
back to a stable sine wave AC power before it is output.
When a commercial power failure is detected, the unit switches to battery supply to provide
continuous sine wave output. This is especially suitable for use where power supply conditions are
poor (for example, when there are large variations in voltage)
Output capacity is 1500VA/1200W for BU150R.
