This device is intended for “heat or cool” fixed temperature applications where front panel controls and digital readouts are not required. The HY-5610 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 Amperes of current to a TEC and will operate from a 5 to 12 Volt power supply.
