Mains power quality should be that of a typical
commercial or hospital environment. If the user
of the TRENDvent ventilator requires continued
operation during power mains interruption, it
is recommended that the TRENDvent ventila-
tor is powered from an uninterrupted power
supply (UPS) or a battery.
