Power modules

Each power module is a single UPS with nominal power of 6.7 kW, extremely compact and easy to handle (weighing only 8.5 kg).
They have a plug-in hot swap system and work in parallel with all the modules present to ensure optimum system performance. The power module is the same for all ranges from 20 to 480 kW.

Control drawer

Each control drawer manages up to 36 power modules (for the 480 kW); it contains the control boards and has a drawer stop to prevent it being pulled out too far.
The front panel has a diagnostic multicoloured LED for instant visual communication that of the UPS status and of all communication ports:
SNMP slot, logic level and RS232 communication port and 5 volt-free contacts.


The UPS is provided with two input switches.
These two switches are bridged by default but the connection can easily be removed to obtain two independent input lines.
