DSOS24V v.1.0/III
Fireman's microphone power supply for the voice alarm systems 24V
CODE:
TYPE:
DESCRIPTION
The DSOS24V is designed for uninterruptible power supply of call stations (firefighter's microphone) used in
VAS (Voice Alarm Systems) requiring stabilized voltage of 24V DC (-5%/+5%).
In the case of mains power loss, the PSU immediately switches to battery power. The power supply unit
is housed in a metal enclosure (color red RAL 3001) with space for a 7Ah / 12V battery. The power supply unit
uses maintenance free, AGM or gel batteries (7Ah/12V).
