Product Overview:

The model WHY5640 is a sub-miniature TEC Controller that can be used in thermoelectric or resistive heater temperature control applications.

It is a general purpose analog PI (Proportional, Integral) control loop and maintains precision temperature regulation using an active resistor bridge circuit that operates directly with thermistors or RTD temperature sensors. Supply up to 2.2 Amps of heat and cool current to your TEC from a single +5 Volt power supply.

The WHY5640 is specifically designed to operate in a master/slave output current boosting confi guration. You can connect two or more WHY5640 units together and drive higher output currents. A single resistor or trimpot sets the temperature setpoint. Independent heat and cool current limits are set by single resistors. A single resistor sets proportional gain. A resistor / capacitor in series sets the integrator time constant.

The WHY5640 can also operate with unipolar current for Resistive Heaters.
