NeTYS 400-1000 VA Product Manual
GENERAL DESCRIPTION
2. GENERAL DESCRIPTION
NeTYS: sure power supply for PC, servers, graphics stations and network devices.
The main purpose of the UPS is to protect sensitive and critical equipment from electrical disturbances that
can compromise operation. Black-outs, brown-outs, variations in voltage and frequency, lightning,
electrostatic discharges and rapid over voltages are phenomena found in all office and industrial
environments and which cause damage to the hardware and loss of data.
NeTYS is an Uninterruptible Power Supply designed to power computers and connected peripherals, with
the exception of any other electrical device (such as household appliances, television sets, stereo systems
and video recorders).
INTRODUCTION
The characteristic feature of these
UPS is the constant monitoring of the power supply which, duly filtered
and stabilised (on models with AVR) and if considered suitable, is used to supply consumers. In cases of a
mains failure or if the mains is considered to be outside limits accepted by the load, the inverter (the heart of
the UPS) is activated immediately. Drawing on the power stored in the batteries, the inverter generates a
voltage that instantly takes over from the mains without any disruption to the equipment connected.
During operation under emergency conditions, the internal batteries discharge but are recharged again
automatically when mains power returns.
Being hermetically sealed, the batteries do not require maintenance of any kind at any stage of their working
life.
