1. GENERAL OVERVIEW
1.1.
UPS GENERAL DESCRIPTION
These UPS families have the compact construction, with the outer metal frame and the electronic circuits and
power components inside. All user accessible elements are placed on the back side, while the control panel –
on the front side.
The top and side covers can be removed, giving an access to the internal part of the UPS for the service or
maintenance purposes.
The front side of all units contains the user interface panel useful for monitoring, maintenance and control.
The terminal block for the electrical connection to the mains, reserve, load, external batteries, and the main
switch, are located on the back side of the unit.
The internal batteries are placed in the lower part of the UPS, with an access from front side.
1.1.1. UPS APPLICATIONS
The new UPS family was designed to provide stabilized and filtered power, especially for supplying
sophisticated and sensitive electronic devices (i.e. for data processing systems). Alcor and Mizar UPSes
can be used to supply electronic systems of medical centers, police stations, motorway tunnels,
broadcasting stations, banks, technical and administrative offices, requiring the power source free from
voltage and frequency variations.
1.1.2. POWER AND AUTONOMY
Thanks to its modular design, the UPSes are available in two series with rated power from 10kVA to 15kVA
(Mizar) and from 20kVA to 40kVA (Alcor).
These two families have different power sections, while batteries and cabinet remain the same.
Both UPSes can utilize the internal battery block of 60 pcs. of 5, 7.2 or 9Ah batteries.
An external battery modules can be used to increase the UPS autonomy.
1.1.3. SAFETY AND SIMPLICITY OF USE
All the UPS elements available for user daily maintenance are insulated and disconnected from hazardous
voltages.
Control of the overload and excessive temperatures guarantees the immediate and most suitable
intervention in the case when one of these conditions occurs during operation
.
The operator can view the UPS status on the front panel and perform shut down or switching operations
easily (see chap. 3 page 19).
The unit is provided with the E.P.O. (Emergency Power Off). This function is activated by pressing the
button located on the front panel.
A remote E.P.O (optional) switch can be connected to UPS to provide remote emergency power off action.
The UPS state can be easily monitored with the personal computer and an interacting program (optional) or
through the remote panel (optional), especially when the UPS is installed in unmonitored areas. See chap.
