BN50T/BN75T/BN100T/BN150T/BN220T/BN300T 1
Introduction
Features of this product
Thank you for purchasing Omron's Uninterruptible Power Supply (UPS).
lThe UPS protects computers and other devices from power failures, voltage variations, instan-
taneous voltage drops, and surge voltage such as that caused by lightning (a phenomenon in
which extraordinary high voltage occurs instantaneously).
lBN50T/BN75T/BN100T/BN150T/BN220T/BN300T are line interactive UPS with simple output
voltage adjustment functions. Under normal service conditions, commercial power input passes
through the transformer and is output, and when the input voltage is low, the transformer raises
the voltage, and when the input voltage becomes high, the transformer lowers the voltage. In
addition, when abnormalities in commercial power are detected, such as in a power failure or
when there are large changes in voltage, power supply is shifted to the battery within 10ms, and
sine wave output is continued.
lOutput capacity is 500VA/450W for BN50T, 750VA/680W for BN75T, 1kVA/900W for BN100T,
1.5kVA/1350W for BN150T, 2.2kVA/1980W for BN220T, 3kVA/2700W for BN300T.
