October 12, 2020 – Acuity Brands company Iota says its ILBHI HV Series is the first emergency driver design to bring its constant power performance to 347-480VAC applications.

The series accepts incoming high-voltage AC power to operate 55-250VDC LED luminaires for 90 minutes during a loss of normal power. The 347-480VAC input eliminates the need for step-down transformers. Two ILBHI HV constant power models are available (20W and 30W) for delivering egress illumination levels that remain consistent for the full emergency run-time.

Self-diagnostic electronics automatically conduct monthly and annual tests, while the LiFePO4 battery technology minimizes size and weight.
