1 Purpose of VAS-Power Supply
Power supply unit VAS-PS21 is created to supply backup low voltage (12V and 24V) to
power amplifiers and other equipment of Public Address and Evacuation management system.
Unit also may be used to supply power to emergency light system, other technical
systems such as light emergency signs, electromagnetic locks of emergency exits, siren
generators etc.
Unit complies with EN54-16:2008 and EMC Directive 2004/108/EC which is confirmed
by relevant papers.
All units have a built-in battery, charging and battery control system with indication of
condition of battery and circuit voltage, nonswitched DC outputs for 12V and 24V, switched DC
for 24V and switched 220V AC.
