The CTF-Xtra microprocessor-based advanced SCR power controller is designed to control all types of industrial heater loads ranging from 25 A to 60 A and up to 480 Vac in several different configurations. Integral programmable over-current fault protection, powerful system parameter diagnostics, multiple firing mode options, control mode versatility and on-board Modbus communications make the CTF-Xtra an ideal choice for almost any process power control application.

The “Xtra” is an on-board over-current fault protection feature which eliminates the need for extra-rapid fuses, reduces machine downtime and the cost of replacing failed fuses. In applications susceptible to intermittent short-circuits and overloads, the CTF-Xtra power controller can be programmed to restore power automatically when the fault has cleared, preventing complete process shutdown and maintaining production.

The CTF-Xtra runs complete diagnostics of temperature, current (including full or partial load interrupt/heater break), voltage, and power and offers programmable soft start-up and current limiting controls to keep your system safe and reliable while extending the heater life.

The CTF-Xtra also features the powerful and detailed C-PWR configuration software, which allows you to run trends, save historical data and read or write device parameters quickly and easily. Configurations may be saved locally for later retrieval or sent across a network for cloning of other units. This significantly reduces mistakes and system setup time.

The C-PWR Configuration Software permits efficient programming of the following Chromalox SCR power controllers: CTF, CTF-Xtra, C4, C4-IR, CFW, and CFW-Xtra. It will facilitate the cloning of multiple controllers and fast parameter file uploads and downloads to and from the controller and PC.

Parameter value settings may be entered via the master table or through the Setup Wizard which methodically walks you through the main screens. Use the C-PWR Configuration Software Manual for program installation and connection details. To program your specific SCR controller, use the appropriate controller programming manual.

Current Release Version: 1.3.0
(Note: New configuration software releases occur without notice. If you need to update your release, you must first uninstall your current version prior to installing the latest release. This may be done in Programs and Features located in the Windows Control Panel.)
