Atlas Sound AP-S20RT – 20A Rack Power Conditioner with Remote

Product Overview

The Atlas Sound AP-S20RT is a 1U rack-mount 20A AC power distribution and conditioning unit designed to protect commercial AV equipment from power-related failures. As a 20A rack power conditioner with remote activation, it addresses the full range of threats to sensitive electronics: EMI/RFI noise, voltage spikes, surges up to 6000V, and unsafe line voltage conditions. The remote activation feature — triggered by a latched dry contact closure — makes the AP-S20RT well suited for larger AV system installations where centralized power control and emergency shutdown are required.

Product Description

The AP-S20RT provides 9 total AC outlets: 6 switched rear-panel outlets, 2 unswitched rear-panel outlets, and 1 unswitched front-panel convenience outlet. Switched outlets can be controlled remotely via a dry contact or DC voltage input, enabling integration with fire control panels as an Emergency Power Down (EPD) system. The unit incorporates EVS (Extreme Voltage Shutdown), which automatically removes power from switched outlets if line voltage falls below 101V or rises above 132V, protecting connected equipment from sustained overvoltage or undervoltage conditions. Built-in RFI filtering attenuates noise from radio transmitters and wireless devices on AC lines, while EMI filtering reduces interference from motors and switching power supplies — both of which can manifest as visible noise on video outputs or audible interference in audio systems. The spike suppression circuit responds within a nanosecond and can sustain clamping for up to 2 milliseconds, handling spikes up to 6000V and surge currents up to 3000A. A front-panel AC fault LED illuminates if suppression circuitry is damaged. A rear-mounted bypass switch disables remote activation when local control is needed. A front USB charging port and a rear XLR connector for the optional AP-GNL18 gooseneck rack lamp add practical utility for system technicians. With a 1U form factor and 9-foot power cord, the AP-S20RT integrates cleanly into standard equipment racks serving boardrooms, government spaces, and professional AV deployments.

Key Features

• 9 Total AC Outlets — Six switched rear outlets, two unswitched rear outlets, and one unswitched front convenience outlet provide flexible power distribution.
• Remote Activation via Dry Contact or DC Voltage — Allows up to 20A of switched power to be turned on or off from a remote location using a latched contact closure.
• Emergency Power Down (EPD) — Integrates with fire control panels to cut power to switched outlets upon a safety event.
• EVS (Extreme Voltage Shutdown) — Automatically disconnects switched outlets if AC mains drops below 101V or exceeds 132V AC.
• Spike Suppression to 6000V / 3000A — Nanosecond response time with suppression sustained up to 2 milliseconds protects against fast transient events.
• RFI and EMI Filtering — Reduces radio frequency and electromagnetic interference introduced on AC lines by nearby wireless devices, motors, and switching supplies.
• Circuit Breaker Protection at 20A — Internal 20A breaker prevents overloads from damaging connected equipment or wiring.
• Remote Status LED Terminals — 12VDC at 100mA available to power a remote indicator LED showing activation status.
• Front USB Charger Port — Provides a charging port for mobile devices or low-current accessories directly on the rack front panel.
• Rear XLR Connector for Gooseneck Lamp — Accommodates the optional AP-GNL18 LED rack lamp for rear-of-rack illumination.

Typical Applications

• Boardroom
• Conference room
• Government space
• House of worship
• Multi-purpose room

• Broadcast studio

Technical Specifications

Frequently Asked Questions

Q: Can the AP-S20RT be integrated with a fire alarm or building automation system?

A: Yes. The Emergency Power Down (EPD) feature uses the Remote Activation contact closure to cut power to switched outlets when an external safety condition is triggered. Keeping the remote contact closed until a fire or emergency condition opens it removes power from switched outlets automatically.

Q: What is the difference between the switched and unswitched outlets?

A: The six rear-panel switched outlets are controlled by the remote activation circuit and can be turned on or off remotely or by the front panel. The two rear unswitched and one front unswitched outlets remain powered at all times regardless of remote activation state.

Q: Does the AP-S20RT regulate voltage or just shut down on extremes?

A: The AP-S20RT does not actively regulate voltage. It monitors the AC mains and activates EVS (Extreme Voltage Shutdown) if the line falls outside the 101–132V AC safe operating range, disconnecting the switched outlets to protect equipment.

Q: What remote LED indicator capability does the unit offer?

A: A 12VDC / 100mA output is available at the remote status LED terminals on the rear panel. This allows an installer to wire a small LED indicator at a remote location to show whether the switched outlets are active.

Q: What is the warranty on the AP-S20RT?

A: AtlasIED covers the AP-S20RT with a 1-year limited warranty. Contact AtlasIED or your authorized distributor for warranty service details.
