NETYS PR RACK 1U- Ref.: IOMNETPRXX01-GB 02
ENGLISH
The main purpose of the UPS is to protect sensitive and critical equipment from electrical disturbances that can compromise opera-
tion. 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).
2.1. 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.
