SurgeX SEQ 120V/20A Sequencing Surge Eliminator and Power Conditioner, 2RU

The SurgeX SEQ is a professional-grade 2RU rackmount power conditioner and sequencer, engineered to deliver advanced surge protection, power sequencing, and conditioning for sensitive audio, video, broadcast, and computer equipment. Designed for demanding environments, the SEQ ensures reliable operation by mitigating power anomalies that can disrupt performance or damage valuable gear.

Featuring SurgeX's proprietary Advanced Series Mode® surge elimination technology, the SEQ provides non-sacrificial surge protection up to 6,000 volts with zero let-through voltage. It also incorporates Inrush Current Elimination (ICE®) to prevent damage from power-up surges and Catastrophic Over/Under Voltage Shutdown (COUVS®) to safeguard against voltage fluctuations. The unit includes 14 industrial-grade AC outlets—three sequenced banks of four outlets and two always-on outlets—allowing for flexible power distribution and sequencing. An intuitive front-panel LCD display provides real-time AC line voltage monitoring and system status, while settings are stored in non-volatile memory for consistent performance across power cycles.

Key Features

• Advanced Series Mode® Surge Protection: Eliminates surge energy up to 6,000V without producing harmful side effects such as ground contamination or common-mode disturbances.
• Inrush Current Elimination (ICE®): Softly powers up connected equipment to prevent inrush current damage.
• Catastrophic Over/Under Voltage Shutdown (COUVS®): Automatically disconnects power during voltage anomalies to protect connected devices.
• 14 AC Outlets: Includes three sequenced banks of four outlets and two always-on outlets for flexible power management.
• LCD Display: Provides real-time AC line voltage and system status information.
• Non-Volatile Memory: Stores settings to ensure consistent performance across power cycles.
• Expandable: Can control other SurgeX products or be daisy-chained with additional SEQ units for larger systems.
• Remote Control Capability: Supports DC voltage or contact closure feedback to control systems like Crestron or AMX.
• Made in the USA: Built with quality craftsmanship and reliability.
