20A SmartSequencing Power Conditioner (CN-2400S)

20A SmartSequencing Power Conditioner (CN-2400S)

120 Volts 

The new CN-2400S is one of the first products to feature Furman SmartSequencing™ technology, which allows large and complex A/V systems to be safely powered on and off with a simple press of a button or turn of a key, even by nontechnical personnel. SmartSequencing’s bidirectional communications between installed units enables a primary unit to control and sequence multiple secondary units, ensuring multizone electronic systems are powered on and off safely and dependably from a single control point across an entire installation. Units can be connected via current loop at runs of more than 1,000 feet with backwards compatibility with Furman’s legacy sequencers.

Description

The CN-2400S is a cutting-edge power management solution designed for professional A/V installers, offering seamless integration with complex systems and superior protection for sensitive electronics. Equipped with Furman’s groundbreaking SmartSequencing™ technology, the CN-2400S simplifies power control for large multizone A/V installations. A simple push of a button or turn of a key can safely power on or off entire systems, even by nontechnical users, with bidirectional communication to manage multiple units from a single point.

 

Key features include:

  • SmartSequencing™ Technology: Enables safe, bidirectional sequencing of power across multiple units with simple controls, ensuring reliable operation.
     
  • Advanced AC Protection: Series Multi-Stage Protection (SMP) safeguards against surges and spikes, while Extreme Voltage Shutdown (EVS) automatically powers down during unsafe voltage conditions.
     
  • Noise Filtration: Linear Filtration Technology (LiFT) ensures audio and video clarity by reducing AC noise across a wide bandwidth.
     
  • Comprehensive Control Options: RS-232 ports and command sets allow easy integration with external control systems.
     
  • Nine Outlets for Versatile Use: Featuring eight rear panel NEMA 5-20R outlets (six sequenced, two unswitched) and one front panel NEMA 5-15R convenience outlet.


Designed for demanding environments, the CN-2400S offers robust functionality with diagnostic lights for monitoring system performance, configurable DIP switches, and support for long-distance connections of up to 1,000 feet. With its industry-leading protection, control, and sequencing, the CN-2400S is the ultimate solution for safe and efficient power management in commercial A/V installations.
