Atlas Sound AP-C15D – 15A Rack Power Conditioner with Digital Voltmeter

Product Overview

The Atlas Sound AP-C15D is a 1U rack-mount 15A power conditioner and distribution unit providing 10 total AC outlets with EMI/RFI filtering, dual clamping spike and surge suppression, and Extreme Voltage Shutdown (EVS) protection. As a 15A rack power conditioner with digital voltmeter, the AP-C15D gives AV system integrators real-time visibility into AC mains voltage directly from the front panel, a practical advantage when diagnosing power quality issues in installations where voltage anomalies are a recurring concern. ETL certification to UL 1449 confirms that the suppression and filtering components meet recognized safety standards for commercial AV and IT equipment protection.

Product Description

The AP-C15D distributes AC power across 10 outlets: 6 filtered and switched rear-panel outlets, 1 filtered unswitched rear outlet, 1 unswitched rear outlet, and 2 unswitched front-panel convenience outlets. This outlet configuration allows critical system components to be separated from general convenience loads while keeping frequently accessed devices on front-panel outlets. The front-panel digital AC voltmeter provides continuous mains voltage monitoring, making it straightforward to identify whether incoming power quality is within normal operating range. An Abnormal Voltage indicator LED flashes if the AC mains is between 101–107V or 128–132V AC, providing an early warning of supply problems that could stress voltage-sensitive equipment. If voltage falls below 101V or exceeds 132V, the EVS circuit automatically disconnects all switched outlets until manually reset, preventing equipment damage from sustained out-of-range supply conditions. The dual clamping spike and surge suppression (DCS) circuitry addresses fast transient events that the EVS circuit is not designed to handle. RFI filtering reduces interference from radio transmitters and wireless devices on the AC line, while EMI filtering reduces noise from motors and switching power supplies. A pull-out front-panel LED tube light with 2-position dimmer provides rack illumination for installation and maintenance work. A rear XLR connector supports the optional AP-GNL18 16" gooseneck LED rack lamp for rear-of-rack lighting. The 9-foot power cord and 1U form factor make the AP-C15D straightforward to integrate into standard 19" equipment racks in boardrooms, government facilities, and conference rooms.

Key Features

• Digital Front-Panel AC Voltmeter — Displays real-time mains voltage for power quality monitoring without external test equipment.
• 10 Total AC Outlets — Six filtered switched rear outlets, one filtered unswitched rear outlet, one unswitched rear outlet, and two front-panel convenience outlets.
• EVS (Extreme Voltage Shutdown) — Automatically disconnects switched outlets when mains voltage falls below 101V or exceeds 132V AC; requires manual reset.
• Abnormal Voltage Indicator — Front-panel LED flashes when voltage is in the marginal 101–107V or 128–132V range, warning of supply quality issues before shutdown.
• Dual Clamping Spike and Surge Suppression (DCS) — Two-stage protection circuitry handles fast transient spike and surge events that could damage sensitive electronics.
• RFI and EMI Filtering — Reduces AC line noise from radio transmitters, wireless devices, motors, and switching power supplies.
• 15A Circuit Breaker Protection — Internal breaker prevents overloads without requiring fuse replacement.
• Pull-Out Front LED Light with Dimmer — Built-in rack light with 2-position dimmer illuminates equipment rack during installation and servicing.
• Rear XLR Connector for Gooseneck Lamp — Supports the optional AP-GNL18 LED lamp for rear-of-rack illumination.
• ETL Certified to UL 1449 — Third-party safety certification validates suppression component performance to recognized industry standards.

Frequently Asked Questions

Q: What is the difference between the AP-C15D and the AP-S20RT?

A: The AP-C15D is a 15A unit with a digital voltmeter, 10 outlets, and a built-in front-panel rack light. The AP-S20RT is a 20A unit with remote activation (dry contact closure), making it suitable for systems requiring programmatic power control or EPD integration with fire control panels.

Q: Does the AP-C15D regulate voltage?

A: No. The AP-C15D monitors voltage and activates EVS shutdown if the mains goes outside the 101–132V AC range, but it does not actively regulate or stabilize voltage. For true voltage regulation, a separate AVR or UPS would be required.

Q: What happens after an EVS shutdown occurs?

A: After EVS activates, power to switched outlets is removed and must be manually reset once the mains voltage returns to a safe level. The front-panel abnormal voltage indicator provides visual confirmation of the condition.

Q: Can I use the AP-C15D with equipment that draws more than 15A?

A: No. The total current draw across all outlets must not exceed 15A. The internal circuit breaker will trip if the combined load exceeds this limit.

Q: What is the warranty on the AP-C15D?

A: The AP-C15D carries a 1-year limited warranty from AtlasIED. Contact AtlasIED or your authorized distributor for warranty service procedures.
