| Ac voltage emergency supply
Technical data |
FEATURES
The apparatus of this series are outcome of a long experience
both in Uninterruptible Power Supply field and in this
specific one. The double conversion technology assures
a complete protection of the users from main disturbances:
for that reason, these apparatus are studied to feed emergency
lighting devices and privileged users.
PRINCIPALES OF WORKING
The users can be divided in two typologies:
1) Users always feed (SA). They are fed in both conditions,
with and without the main.
2) Users feed only in emergency condition (SE). They are
fed only in back up condition without the main.
- Working as UPS. With the main present, the SA users are
fed by the inverter (stabilized and filtered output voltage),
in power failure condition, the inverter feeds both SA and
SE users.
- Working as Emergency Supply (eco-mode). To reduce the losses,
in alternative to the previous way of working, it is possible
the following method: with the main present, the users are
fed directly by the main, in power failure condition, the
inverter feeds both SA and SE users.
- In both way of working it is possible control the feed
of SE users with an external contact.
