All Flex Thermal Controller


All Flex’s AFTC-5000 thermal controller provides easy-to-use heater control using single-button adjustment to advance by pre-set increments. This controller is ideal for OEM’s that do not have sophisticated thermal control requirements, engineers and product developers who are experimenting with thermal requirements of their design, and manufacturers that offer end-users the ability to adjust thermal levels.

The controller utilizes the input power of the heater without the need for a separate power supply. Output power to the heater will shift from full power during ramp-up to PWM (Pulse Width Modulation) during its hold state.

The AFTC-5000 is custom-programmed at All Flex with 6 specific temperature settings defined by the customer. Customers may order online (entering the desired settings during the check-out process) or by placing an order with our customer support team.

Contact All Flex for models with standard settings.
