B2.19.3.6 Uninterruptible Power Supply (UPS)

a. Operating Characteristics

For the safe supply of the servers, operator and engineering work stations and other equipment requiring continuous supply a UPS shall be provided with the following characteristics:

? Rated Output 10 kVA

? Supply Voltage 125 V DC & 110VDC

? Output Voltage 220/230/240 Selectable

? Protection Degree IP41

Under normal input conditions energy from the main circuits is channelled through the AC/DC converter. Surge and spikes will be blocked completely at the input converter and very instable supply shall be supported.

In normal condition the UPS shall be capable to operate in all the 125 or 110 VDC battery conditions (floating voltage, equalizing voltage and final discharge voltage)

In the events of main circuit failure the static switch will transfer the energy to through the transformer. The transfer time shall be not less than 2 ms.

After failure fixing the transfer to normal condition shall be done manually.

A manual by-pass switch shall permit the transfer from normal supply and vice versa for maintenance purpose.

b. Construction Characteristics

The AC/DC converter shall be of last generation type, possibly PWM (Pulse Width Modulation)

The ups shall house the following components:

? one DC/AC inverter;

? one emergency circuits composed by one transformer, reactors

? static switches;

? one manual bypass;

? distribution system.

The transformer shall be dry type with insulation class H and installed on anti-vibration support and placed in such a way to have easy accessibility.

Each output circuit shall be protected by a miniature circuit breaker.

On the front of the board at least the following signalizations shall be foreseen:

? Normal Supply;

? Emergency Supply

? Internal Failure;

? Low output voltage;

? High output voltage;

? Low input voltage;

? Earth fault

It shall be foreseen a communication port for the communication with PC.
