Lowell SEQ-4A Sequencer 4-step

Product Description

The LOWELL SEQ-4A is a 4-step sequencer designed for commercial audio and video distribution systems. A sequencer controls the power-on and power-off order of connected equipment, preventing simultaneous inrush current that can trip breakers or damage components. This type of device is commonly specified by AV integrators and commercial electricians working on installed sound systems, conference rooms, and multi-zone display setups. The SEQ-4A manages four discrete switching steps, allowing equipment to energize and de-energize in a controlled sequence rather than all at once.

The SEQ-4A is suited for commercial-grade installations where multiple pieces of powered equipment must be brought online in a defined order. Typical applications include rack-mounted AV systems, commercial display arrays, and distributed audio installations. It is sold in single-unit quantities and is intended for professional installation in commercial environments.

Key Features

• 4-step sequencing for controlled power-on and power-off of connected equipment
• Prevents simultaneous inrush current across multiple loads
• Commercial-grade construction for rack or panel installation
• Single-unit packaging suitable for individual system builds

Compatibility

Designed as an OEM-style replacement or direct-fit component for commercial AV rack systems requiring 4-step power sequencing control.

Installation Notes

Installation should be performed by a licensed electrician or qualified AV integrator familiar with commercial power distribution and NEC requirements. De-energize the rack or panel completely before wiring the sequencer. Verify load ratings for each step against the connected equipment draw before commissioning. Follow the manufacturer wiring diagram included with the unit.
