| UPS SINGLE PHASE ON-LINE RACK 19”, SR 1 ÷ 3kVA SERIES |
The SR series on line double conversion UPS with full time Digital Signal Processor control technology is the perfect solution for
mission critical users who demand high reliability, availability and performance from a UPS. The rack/Tower convertible design,
input power factor correction, and high efficiency provide a superior level of power quality for sensitive electronic equipment
and computers loads.
PRINCIPLES OF WORKING
The backup series is composed by: Rectifier, Inverter, Static Switch, manual by-pass and Battery.
The Rectifier-Inverter line normally feeds the users, and the Battery is kept charged by the Rectifier. If a black out occurs,
the Battery supplies power energy to users always through the Inverter. When the blackout is over, the Rectifier provides for
Battery charge.
If a short circuit or an overload occurs to the users, the Static By-pass switches the load over the emergency line. When the fault
is over, the Inverter feeds users.

INTERFACES
In additional to the standard RS232 with software, the SPH Series UPS also provides 2
additional customer options communication slots.
Standard serial RS 232
The smart port is an intelligent RS232 serial port that allows the UPS to a computer. The connector is
a standard D-Type, 9 pin, female. The software optionally allows the computer to monitor the mains voltage and the
UPS status continuously.
Dry contact card provides isolated contacts for industrial and remote alarm application.
|
|
2nd RS232, RS485 and USB port for remote signaling and automatic computer shutdown.
SNMP card for monitoring and integration in network management. The Simple Network Management Protocol
(SNMP) is a worldwide-standardized communication-protocol. It is used to monitor any device in the network via simple
control language.
The Emergency Power Offfacility must use a normally NO contact, which closes to operate the emergency stop procedure.
The emergency stop port is located at the rear of the UPS SPH module. Through the dry contact interface it is available also
a NC contact.
The SR series UPS is provided with monitoring and shutdown software. The monitoring software provides real-time UPS status
display via easy-to-read Meter and Gauges, Digital Table, Block Diagram and Graph Chart as well as remote monitoring of the
UPS through Intranet or Internet.
The software is compatible with many operating systems such as Windows 98, 2000, XP, Vista and Windows 7 For other applications
like Novell, NetWare, Unix, Linux, please contact your local distributor for a proper solution.

ACCESSORIES
- Additional battery cabinets to upgrade the backup time till several hours even after the first installation.
On request the add battery cabinet can be provided with an external independent battery charger to guarantee a fast recharge.
|
|
- External Bypass Switch Box Series. Beyond to the standard manual by-pass fitted in each UPS, the external maintenance bypass
and power output distribution switch allows you to manually transfer the connected equipment to utility power via a maintenance
bypass switch and vice versa. It is available till 400 A and it is suitable for single UPS and for a system composed till no.
4 UPS in parallel.
