UNINTERRUPTIBLE POWER SUPPLY
Single phase ON-LINE double conversion Rack 19” UPS,
SR 5kVA ÷ 10kVA series
Single phase ON-LINE double conversion Rack 19” UPS, SR 5kVA ÷ 10kVA 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. Input power factor correction, high efficiency and parallel redundant capability (N+X) 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.

CONTROL PANEL

The front display panel provides all major systems parameters and operational status of the UPS that include full diagnostics for simple, easy servicing. The SR series UPS with DSP control, systematically checks each component and displays the result using on LCD display. This feature allows service technicians the ability to pinpoint and repair the UPS very quickly.

N+X POWER SCALABLE PARALLEL REDUNDANCY

The SR UPS may be paralleled for power capacity or for redundancy up to 4 units to increase the power capacity or configuring a parallel redundant UPS system.



The standard apparatus can be simply interconnected up to 4 units using the CAN-bus RJ45 cables on the rear of the SR series UPS. The SR series UPS used an inverter control technology that allows to achieve N+1 scalable redundant power without the use of additional components. Parallel Distribution Box are available till 200 A (40kVA).

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 Off facility 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.

- Optional External 1000W Charger. Its independent electronic control allows to the device to work in parallel up to 4 units. The external battery charger is foreseen to be placed on back of the cabinet.



- 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.











- Rail kit to support UPS in rack 19” cabinet.
