TC621HCPA

Applications Field of TC621HCPA and Working Principle

TC621HCPA is a precision temperature controller/thermostat with solid state output. This integrated circuit is used in a variety of consumer, industrial, and automotive applications that require temperature-measurement and control. It offers numerous advantages over mechanical thermostats, such as longer lifetime, better stability, accuracy, and durability. In addition, its cost is lower than that of a mechanical thermostat.

Temperature Range

The maximum temperature range for the TC621HCPA is 85 deg-C to +125-degrees C. It also has a temperature accuracy of +/-1deg-C. The temperature range and accuracy make it a suitable choice for various temperature-related applications, such as in food cooking, wine-cooling, HVAC systems, automotive climate control systems, and other industrial applications.

Thermostat Operation

The TC621HCPA thermostat works by sensing the temperature of the surrounding environment and comparing it to a user-set point. If the temperature deviates from the set point, the solid state output is activated. This effect is regulated with a stable low-power voltage regulator (3.3 VDC) and an LED to provide visual indication of the output.

Solid State Outputs

The TC621HCPA offers a solid state output, allowing for the reliable control of industrial machinery or other temperature-sensitive processes. The solid-state output, which is a low-voltage barrier, is configured as a transistor switch that will activate when the temperature exceeds the set point. The outputs are rated up to 1000vDC, allowing for the control of high power devices such as fan motors, heaters, HVAC systems, and other environmental control devices.

Thermal Shutdown

The TC621HCPA is equipped with an internal temperature monitor, which will activate thermal shutdown when the temperature exceeds its limit. This safety feature helps to protect the device from excessive heat damage. Additionally, the TC621HCPA also comes with a wide tolerance range for operation, allowing it to work in extreme temperatures.
