AtlasIED ECS-3 15A AC Power Sequencer and Conditioner

The AtlasIED ECS-3 is a professional 15-amp AC power sequencer and conditioner designed to provide controlled power distribution and electrical protection for commercial audio, video, and installed AV systems. Featuring three sequential power stages, nine AC outlets, surge suppression, and integrated voltage monitoring, the ECS-3 helps simplify equipment startup and shutdown while protecting connected electronics.

Housed in a compact 1RU rackmount chassis, the ECS-3 provides six sequenced rear-panel outlets divided into three controlled stages, along with three unswitched convenience outlets. This arrangement allows installers to manage the power-up and power-down order of connected equipment while maintaining continuous power for devices that do not require sequencing.

The ECS-3 incorporates Dual Clamping Spike and Surge Suppression (DCS), EMI/RFI noise filtering, and Extreme Voltage Shutdown (EVS) protection. A front-panel digital AC voltmeter provides convenient monitoring of incoming line voltage, while an integrated circuit breaker and status indicator assist with system protection and troubleshooting.

With local and remote activation options, a pull-out LED rack light, and optional keyed wall control, the AtlasIED ECS-3 is well suited for professional sound systems, commercial AV equipment racks, houses of worship, schools, and other installations requiring dependable power sequencing.

Three-Stage AC Power Sequencing

One of the primary advantages of the AtlasIED ECS-3 is its ability to control the order in which connected equipment receives power.

The ECS-3 features three sequential timing sections that activate connected devices in stages rather than energizing all controlled outlets simultaneously.

This is especially useful in professional audio systems where equipment startup and shutdown order can help reduce unwanted speaker pops and other switching-related noise.

For example, a properly configured audio system can power source equipment and signal processors before activating downstream power amplifiers.

During shutdown, the sequencing arrangement can reverse the process to help protect connected loudspeakers from unwanted transients.

The three-stage design makes the ECS-3 a practical choice for commercial AV systems with multiple equipment components.

Nine AC Outlets for Flexible Power Distribution

The AtlasIED ECS-3 includes nine AC outlets divided between sequenced and unswitched connections.

Outlet Configuration

Outlet Type	Quantity	Function
Rear Sequenced Outlets	6	Controlled through three sequencing stages
Front Unswitched Outlets	2	Convenience power connections
Rear Unswitched Outlet	1	Continuous power connection
Total AC Outlets	9	6 sequenced and 3 unswitched

The six sequenced outlets allow installers to assign compatible equipment to the appropriate startup and shutdown stages.

The three unswitched outlets provide power for devices that need to remain energized independently of the sequencing operation.

The ECS-3 has a total current rating of 15 amps. The nine outlets do not each provide an independent 15-amp capacity.

Connected equipment loads must remain within the unit's rated electrical capacity.

Dual Clamping Spike and Surge Suppression

The ECS-3 incorporates Dual Clamping Spike and Surge Suppression (DCS) technology to help protect connected equipment from transient AC voltage disturbances.

Electrical spikes and surges can occur during switching events or other disturbances on the AC power line.

The ECS-3's suppression circuitry is designed to help limit the effects of these disturbances on connected equipment.

Manufacturer-listed protection specifications include:

• Minimum spike clamping voltage: 460 VRMS at 3000A
• Maximum spike clamping voltage: 6000V

These specifications describe the manufacturer's stated surge protection characteristics rather than normal operating voltage.

For commercial AV systems containing amplifiers, signal processors, and control equipment, integrated surge suppression provides an additional layer of electrical protection.

EMI and RFI Noise Filtering

Professional audio and video equipment can be affected by electrical interference entering through the AC power line.

The AtlasIED ECS-3 includes Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) filtering designed to reduce conducted electrical noise.

This filtering is useful in installations containing:

• Audio signal processors
• Commercial amplifiers
• Digital mixers
• AV control equipment
• Video system components
• Other sensitive electronics

By reducing unwanted interference on the incoming AC line, the ECS-3 supports cleaner power delivery to connected equipment.

Extreme Voltage Shutdown Protection

The ECS-3 features Extreme Voltage Shutdown (EVS) circuitry designed to help protect connected equipment during abnormal incoming voltage conditions.

The manufacturer's specified operating voltage range is:

102–132VAC

The EVS protection system is designed to respond to voltage conditions outside the intended operating range.

This feature is particularly valuable in commercial AV installations where connected equipment may remain powered for extended periods.

The ECS-3 provides protective shutdown functionality; it is not a voltage regulator or battery backup system.

Front-Panel Digital AC Voltmeter

The AtlasIED ECS-3 includes a front-panel digital voltmeter that displays incoming AC mains voltage.

This allows installers and technicians to monitor line voltage directly from the equipment rack.

The display can be useful when checking electrical conditions during installation, maintenance, or troubleshooting.

By providing a convenient visual reference, the voltmeter helps technicians identify abnormal voltage conditions without requiring access to the rear of the equipment rack.

Local and Remote Power Sequencing Control

The ECS-3 supports both local and remote sequencing activation.

A front-panel momentary switch provides convenient local control.

Rear-panel trigger inputs support remote activation using:

• Momentary contact closure
• 5–24VDC trigger signal

These options allow the ECS-3 to integrate with compatible remote control systems.

Remote activation is particularly useful in commercial installations where equipment racks are located in secured rooms or away from the primary operating position.

Optional Keyed Remote Wall Control

For installations requiring additional control security, the ECS-3 supports the optional AtlasIED WPD-KSWM remote key-lock wall plate.

This accessory provides a keyed control option for compatible power sequencing installations.

A keyed remote control can be useful in schools, houses of worship, and commercial facilities where power operation should be restricted to authorized personnel.

The WPD-KSWM is optional and sold separately.

Built-In LED Rack Light

The ECS-3 features a front-mounted pull-out LED light designed to illuminate nearby equipment controls.

The light includes a two-position dimmer for adjusting illumination.

This feature is especially convenient in equipment rooms, backstage areas, and AV racks where ambient lighting may be limited.

The integrated light helps technicians identify controls and equipment labels without requiring a separate rack light.

Circuit Breaker Protection and Status Indicator

The AtlasIED ECS-3 includes circuit breaker protection and a dedicated breaker-open indicator.

The indicator provides a visual reference when the breaker has opened.

This feature can assist technicians during system troubleshooting and maintenance.

The circuit breaker works alongside the ECS-3's surge suppression and voltage protection features to support dependable power management.

Compact 1RU Rackmount Design

The AtlasIED ECS-3 is designed for installation in standard 19-inch equipment racks.

Its dimensions are:

• Height: 1.75 inches
• Width: 19 inches
• Depth: 8.5 inches

The compact 1RU chassis allows the ECS-3 to provide power sequencing, surge suppression, and voltage monitoring without occupying excessive rack space.

This makes it a practical solution for commercial AV equipment racks where efficient use of space is important.

Ideal Applications for the AtlasIED ECS-3

The ECS-3 is suitable for professional installations requiring controlled AC power sequencing and electrical protection.

Common applications include:

• Professional audio equipment racks
• Commercial AV systems
• Houses of worship
• School sound systems
• Corporate conference facilities
• Performing arts venues
• Commercial paging installations
• Background music systems
• AV control rooms
• Installed sound reinforcement systems

Its three-stage sequencing design is particularly useful in systems where amplifiers, processors, and source equipment need to power on and off in a controlled order.
