The CTF is a compact microprocessor-based SCR power controller which is designed for all types of industrial heater loads up to 250 Amps at nominal voltages of 480, 600 and 690 Vac. The CTF will safely and precisely control traditional resistive heating elements, infrared lamps and silicon-based elements exhibiting non-linear resistances with its several different user-configurable zero crossing and phase angle control schemes.  User selectable delay trigger, current limiting and soft start control as well as current, voltage and power diagnostics allow optimized power management of the most challenging load types. On board communications and powerful configuration software make the CTF an ideal power control solution for your critical process heating applications.

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.)
