More than just another regulator. The LR3C Controller combines three essential devices in one physical container, making it a lightweight, space-saving, and cost-effective alternative for any aircraft electrical system, while also mproving safety of flight. First, the LR3C operates as a “quiet,” linear regulator, generating no audio or radio noise (in contrast to switching-type regulators). Second, it provides a vital safeguard for your aircraft electrical system with a solid-state, “crowbar” overvoltageprotection circuit. And third, the LR3C Controller functions as an important low-voltage monitoring and warning system.
