Controller

The controller will control and monitor all the relevant operating parameters and provide comprehensive information on the current system status. Its main features will be:

• Control and monitoring of operating parameters (voltage, current, temperatures, rectifier status, fuse status, etc).

• Flexible and scalable

• Battery management.    

• Automatic battery test including advanced scheduled and manual tests  

• Battery low-voltage disconnection.  

• Temperature compensation with programmable compensation factor. User-selectable alarm parameters.  

• Audible alarm.   >

• Programmable alarm routing.  

• 10/100 Mbps Ethernet interface + web server support + SNMP v2c communication.

• Local setting interface with LCD screen    

• Operating status LEDs.

Subrack

The power supply must accommodate 2x rectifiers and 1x controller. The subrack will include at least the following :

• 1x 125A battery breaker.¨                                                          

• 4x load breakers (32A, 63A, 100A, 125A).      

• 8x Digital inputs for external alarms.

• 2x Digital outputs (dry contacts).  

• 1x Battery midpoint measurement  

• 2x Temperature sensors.  >

• 1x Battery Low Voltage Disconnect relay.
