The Interposing Relay with UPS Battery monitoring Panel is proposed to drive the electrical loads in AAU panel. By using this unit, we can drive two types of loads of maximum 10A and 40A. And also to monitor/measure the UPS battery voltage and inform the status to alarm panel by using inbuilt Modbus
communication interface .The unit eliminates the use of bigger sized, high cost rotary switch and uses a simple toggle switch for bypass action and drive for the relays which drives the high load. Simple preventive maintenance should be performed on a regular basis to make sure UPS operating at maximum efficiency. This panel is provided to monitor/measure the UPS battery voltage and inform the status to alarm panel by using inbuilt Modbus communication interface .

The user has the following benefits

• Switching heavy loads through the unit instead switching directly from alarm   panel
• Work on any scheduled operation from the alarm panel
• Provided with bypassing option
• Reliable and Secured facility
• Error free switching of high loads
• Modbus RS485 Communication to panel
• Measurement of Voltage with 1% accuracy
• Ability to measure voltage from 0-120V range
