ISL540 Emergency Ballast

Slim Profile Emergency Ballast for Linear LED Retrofit (TLED) and Fluorescent Luminaires

By IOTA

  • Overview
  • Specifications
The ISL540 Fluorescent Emergency Ballast allows the same fixture to be used for both normal and emergency operation. In the event of a power failure, the ISL540 switches to the emergency mode and operates one of the existing lamps for 90 minutes. The unit contains a battery, charger, and inverter circuit in a single can. The ISL540 delivers high performance in a slim design and is ideal for use in linear lighting fixtures where ballast compartment space is limited.
