Furman CN-2400S SmartSequencing Power Conditioner (20A)

Furman CN-2400S SmartSequencing Power Conditioner (20A)



Furman CN-2400S Overview



The 20A SmartSequencing Power Conditioner from Furman is designed for commercial A/V installers and combines robust control capabilities via SmartSequencing Technology, advanced AC protection, AC noise filtration, and optional compatibility with the BlueBOLT Remote Power and Energy Management Platform (BB-RS232 adapter required and sold separately). It combines AC power distribution, protection, filtration, and sequential system power on/off in a 1RU, 120VAC, rackmount unit.

This sequencer features 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 that 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 1000′ (304.8m) with backwards compatibility with other Furman sequencers.

In addition, the CN-2400S offers robust control options, being equipped with RS-232 ports and command sets for integration with control systems. An RS-232-to-Ethernet adapter (sold separately) adds full IP-addressability to the unit, allowing it to be controlled, programmed, and monitored from a smartphone, tablet, PC, or any Web-enabled device via Telnet, direct HTTP connection, or Panamax/Furman’s BlueBOLT-hosted remote power and energy management platform.

Surge Protection

SMP (Series Multi-Stage Protection) technology provides a high level of surge and spike protection. It ensures zero downtime for mission-critical installations by safely absorbing, clamping, and dissipating transient surges and spikes without damage to internal circuitry or connected equipment.

Noise Filtration

LiFT (Linear Filtration Technology) reduces AC noise linearly across a very wide bandwidth for enhanced audio and video clarity. LiFT ensures maximum performance from connected equipment.

Voltage Protection

Extreme Voltage Shutdown (EVS) circuitry safely powers down itself and connected equipment during unsafe voltage periods. EVS safeguards from catastrophic undervoltage (under 80V sustained) or overvoltage (over 145V sustained) conditions. Circuit may be set to auto-reset when voltage returns to normal or manual reset after an event is detected.


SmartSequencing allows bidirectional, safe sequenced power up/down operations of large and complex A/V systems via the push of a button or turn of a key, even by nontechnical personnel.

Diagnostic Lights

Diagnostic lights provide valuable system information including power quality, protection ok indicator, and extreme voltage indicator.

Remote Access (RS-232)

RS-232 compatibility and command set provide integration with control systems, open source, and control programming. RS-232 to Ethernet adapter (sold separately) allows for control, programming, and monitoring from any Web-enabled device via Telnet, direct HTTP connection, or Panamax/Furman’s BlueBOLT platform.

BlueBOLT Compatible

BlueBOLT provides remote access to reboot components, power equipment on/off, and monitor power quality via the Internet from anywhere in the world.
