15A, front panel switch or latching relay, power sequencer

Economical 15A power sequencer for single-rack AV and audio installations. The SQ-1500 is a standalone 15A power sequencer with three delayed output groups for protecting equipment in single-rack installations from inrush current. It provides a 15A capacity distributed across six outlets, grouped into three sequenced steps to prevent harmful inrush current during startup. An additional seventh outlet remains unswitched for devices that require constant power. The design includes integrated surge protection and line noise filtration. The SQ-1500 can be activated locally via its front-panel switch or remotely using a simple latching contact closure, making it ideal for conference rooms, classrooms, and project studios. Front-panel LEDs provide clear, at-a-glance status of the sequencing process.
