The Midsize Inverter Series comes in a surface mount enclosure, and the Micro and Mini Inverter Series offer options for surface mounting, recess mounting, or T-Grid mounting. All units and included batteries come with a 3-year warranty. All models we offer are UL Listed for use in damp locations, and all T-Grid mountable models are plenum rated to UL2043. There are also models certified to the California Energy Commission (CEC) under Title 20 Regulations.

When normal utility power to the inverter is lost, the output is automatically turned on and will provide a minimum 90-minutes of emergency power to the connected lighting load. An internal disconnect circuit will protect the battery from damage from a deep discharge. When normal utility power is restored, the unit will switch the load back to normal utility power, and the internal charger will replenish the battery within the requirements of UL924.

Adding to Functional Devices Lighting Controls emergency lighting products, the inverter series will allow for compliance with most egress lighting needs. For more details on any of our products, please go to our website or contact us directly.
