Quality Power from Furman

The Furman CN-20MP Remote Duplex Power Sequencer allows you to extend your remote power sequencing outside of the equipment rack. It is designed to provide two outlets with sequenced power, and it includes remote control inputs and outputs, enabling daisy-chaining of more units. Customization of parameters for features like sequencing delays, 12V on/off, and more is possible due to an integrated potentiometer and DIP switches. The DIP switches are protected by a security cover, which is supplied. A fire alarm can trigger the CN-20MP to switch off automatically as well.


SmartSequencing allows bidirectional, safe sequenced power up/down operations at the push of a button or turn of a key.

Voltage Protection

Extreme Voltage Shutdown (EVS) safeguards from catastrophic undervoltage (under 77V ±3V sustained) or overvoltage (over 140V ±5V sustained) conditions. The EVS feature can be selectively enabled or disabled, as you prefer.

Diagnostic Lights

Diagnostic lights provide system information, including power quality.

DIP Switch Customization

The DIP switches and potentiometer allow customization of settings such as sequencing delays, 12V on/off, and more. A security cover is provided to prevent unauthorized personnel from tampering with DIP switches.

BlueBOLT Compatible with Optional Equipment

IP Control (Telnet or cloud-based BlueBOLT) via SmartSequencing, when connected to the optional CN-1800S/CN-2400S with a BB-RS232 adapter.

Furman CN-20MP Features
