HY5640 Subminiature Controller

of the HY5640 Pin Outs * Temperature Set Resistor Rs (Pin 1 to Pin 7) The temperature set resistor for the HY5640 controls the temperature at which the TEC will operate. When the circuit has stabilized, the resistance of the thermistor will be equal to that of the set resistor Rs. For exampl.

HY5640 TEC Controller Subminiature Controller for Thermoelectric Coolers The HY5640 is a subminiature temperature controller for thermoelectric coolers (TEC). This device is intended for “heat or cool” fixed temperature applications where front panel controls and digital readouts are not required. The HY5640 uses a thermistor bridge to precisely measure and regulate the temperature of a device affixed to a TEC. With proper heat sinking, the power stage of this device will deliver up to +/- 2 Amp.
