Innovative Energies dual redundant DC UPSs and PSUs

Click2Contact

Innovative Energies’ DC UPS and PSU options feature a variety of communication options including serial and Ethernet versions of Modbus/DNP3, SMS and SNMP for remote monitoring of the battery, power, temperature and control of scheduled or manual battery condition tests.

The redundant system includes two completely independent chargers, isolated by output diodes, so that failure of one system will not result in any loss of DC power to critical loads. Other features include: a low volt disconnect function that will protect the batteries from a life-shortening deep discharge condition; temperature compensated charging voltage to ensure long battery life; and battery detection circuitry giving an alarm if the battery circuit becomes open circuit or if the battery is missing. Voltage/amp and energy meters can be added with ease.

In addition, there are relay alarm contacts for interfacing with other monitoring equipment. SNMP units come with web pages that can be accessed remotely. Alarms received via ‘Traps’ can be investigated further when the user logs in to the web page and interrogates the system status of the unit. This method has been commonly used by many telecommunication network customers worldwide for monitoring hard-to-access remote sites.
