Atlas Sound ECS-3 – 15A Rack-Mount Power Sequencer and Conditioner

Product Overview

The Atlas Sound ECS-3 is a 1RU rack-mount 15-amp power sequencer and conditioner designed to manage AC power distribution, equipment protection, and sequenced startup and shutdown in commercial AV equipment racks. It is used by AV integrators and systems engineers to protect amplifiers, signal processors, and other rack-mount equipment from power surges, voltage irregularities, and improper power-on sequencing. The ECS-3 provides nine total outlets, including six sequenced rear outlets in three independent timing stages, and supports both local front-panel and remote activation for flexible installation in boardrooms, all-hands rooms, and any AV rack requiring sequenced power control.

Product Description

The ECS-3 addresses the full range of AC power management requirements for commercial AV racks. The six rear-panel outlets are divided into three sequential timing stages, allowing integrators to define a power-on order that protects sensitive downstream equipment from in-rush current and sequencing damage. Three additional outlets — two on the front panel and one unswitched rear outlet — are always available for convenience connections. The unit is rated for 15A continuous service and operates within a 102–132VAC range, with Extreme Voltage Shutdown (EVS) protection that automatically disconnects power if the AC mains falls below 102V or exceeds 132V.

Surge and transient protection is handled by dual-clamping spike suppression with DCS circuitry, rated to a minimum clamping voltage of 460 VRMS at 3000A and a maximum clamping voltage of 6000V. Radio frequency and electromagnetic interference (RFI/EMI) filters are included on the AC line. The front panel includes a precision digital AC mains voltmeter for real-time line voltage monitoring, and a pull-out dimmable LED tube light for rack illumination. A rear XLR-style socket supports an optional 16" gooseneck LED lamp (AP-GNL18) for rear rack lighting. Sequence activation can be triggered from the front panel momentary switch, from a rear-panel dry contact closure, or via a 5–24VDC trigger signal — enabling integration with room control systems. A sequenced 24VDC output is available to trigger expansion modules such as the AtlasIED ECM-20SH 20A standalone power module for larger rack systems. The unit is ETL certified to UL 1449 and occupies a single rack unit.

Frequently Asked Questions

Q: How many outlets does the ECS-3 provide and how are they distributed?

A: The ECS-3 has 9 total AC outlets. Six rear-panel outlets are sequenced across three timing stages (two outlets per stage). Two front-panel outlets and one rear-panel outlet are unswitched convenience outlets that are always live.

Q: Can the ECS-3 be triggered remotely by a room control system?

A: Yes. The ECS-3 supports three activation methods: a front panel momentary push button, a rear-panel dry contact closure, and a 5–24VDC trigger signal. The DC trigger input is compatible with control systems from Crestron, AMX, and similar platforms that provide logic-level outputs.

Q: What happens if the AC mains voltage falls outside the operating range?

A: The ECS-3 Extreme Voltage Shutdown (EVS) circuit automatically disconnects all switched outlets if the AC line voltage drops below 102V or rises above 132V, protecting connected equipment from damage due to under-voltage or over-voltage conditions.

Q: Can the ECS-3 be expanded to handle more than 15A?

A: Yes. The ECS-3 provides a sequenced 24VDC output that can be used to trigger the AtlasIED ECM-20SH 20A standalone AC power module, allowing installations with higher amperage requirements to add capacity while maintaining sequenced control from the ECS-3.

Q: Is a remote wall plate available for the ECS-3?

A: Yes. The optional WPD-KSWM key-lock wall plate (sold separately) provides a secure remote activation point for the ECS-3 using a momentary contact closure. A standard push-button wall plate (WPD-SWM) is also available.

Q: What safety certifications does the ECS-3 carry?

A: The ECS-3 is ETL certified to UL 1449, the standard covering transient voltage surge suppression devices.

Q: What is the warranty on the ECS-3?

A: The ECS-3 is covered by AtlasIED's 12-month warranty from the date of purchase.
