  • Overview
  • Specifications
The IOTA IIS 35 HE is a UL Listed pure sine wave output inverter designed to provide power to the designated emergency lighting fixture. In a power loss situation, the IOTA IIS 35 HE will supply 120 or 277 VAC power to operate up to a 35W total connected load for not less than 90 minutes. The IOTA IIS 35 HE works in conjunction with LED, fluorescent, and incandescent lamp and fixture types and will automatically run switched, normally-on, or normally-off designated emergency fixtures. The IIS 35 HE is ideal for applications requiring an emergency source in elevated ceilings, for high output luminaires, and lamp types utilizing Edison Screw (ES) designs. The IIS 35 HE features high-efficiency performance to help meet CEC Title 20 efficiency requirements.
