The Plug Dialog
series includes the 350 and 550VA models. The
load is powered from the mains through an EMI
filter to suppress transients, spikes and electrical
noise. An internal battery provides power protection
from wide fluctuations and blackouts. When the
mains fails, connected loads are powered with
a pseudo sine wave supply from the inverter
and battery supply to provide sufficient runtime
for computer system shutdown using the PowerShield
UPS monitoring and control software supplied
as standard.
