The Solid-State Load Switch is intended for use in 28VDC aircraft electrical systems and can switch currents up to 75A. It’s sealed between the base and top parts and the load terminals, allowing internal pressure equalization through a membrane at the bottom of the unit.
The SSLS meets aviation standards and requirements and is delivered with a COC or EASA Form 1 upon request.
The applicable approval can be provided by us specifically for your aircraft type.
