Info Sheet

The QNET 2.0 HVAC board consists of a chamber with a heater and a brushless DC fan. The heater is a PWM voltage-controlled amplifier that generates heat by applying the input voltage to an array of resistors in parallel. Six high accuracy temperature sensors are placed along the heating channel, with additional sensors measure ambient and heating chamber temperatures. Heat is transferred to the sensors by radiation from the heater and by convection from the air stream.
