The Furman Merit M-8S Power Sequencer is an ideal, cost-effective AC power management solution for any professional rack-mount audio, video, or broadcast system where safe and orderly power sequencing is essential. Designed for reliability and ease of installation, the M-8S ensures your equipment powers up and shuts down in a controlled sequence to prevent harmful inrush currents and protect sensitive gear.
Simply install the M-8S in the top slot of your rack, and its six delayed, rear-panel outlets—organized into three sequenced banks—will automatically power on in order, delivering clean, consistent power for loads up to 15 amps. Two additional unswitched outlets (rear) and one front convenience outlet allow always-on operation for critical devices.
