Standby Power Systems
AROS uninterruptible power supplies
are also designed and built for use in
applications such as central supply
systems for emergency lighting,
security alarms and electro-medical
equipment.
The CEI 64-8 V2, EN 50171 standards
and other guidelines set down the
characteristics and performance levels
required from such systems. The main
ones are summarized below:
• Up to 3 h back-up times
• Battery recharge time of under 12 h
• Galvanically isolated input/output
• High-level diagnostics – preferably
from a front mimic panel
• Remote interface – normally volt-free
contacts
• High short circuit current capability.
The applications require a continuous
power system configured as follows:
• A standard UPS with high capacity
battery charger
• An isolation transformer (option)
• A remote interface to communicate
with other peripherals.
