The advanced and reliable circuitry of the HTC Series achieves 0.0009°C temperature stability. Its low profile package is ideal for designs with space constraints. The ultrastable linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency. The HTC1500-62 drives up to 1.5 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar).

The HTC3000-62 drives up to ±3 A. An evaluation board simplifies prototyping: HTCEVALPCB. A heatsink that mounts directly to the HTC is available: HTCHTSK. The HTC1500-62 is designed for 0.062″ thick printed circuit boards (PCBs). The HTC1500 is designed for 0.031″ thick PCBs.

The HTC Series temperature controllers are easily configured for any design. Virtually any type of temperature sensor can be used with the HTC and a built in sensor bias current source simplifies use with resistive temperature sensors. The independently adjustable Proportional Gain (P) and Integrator Time Constant (I) can be modified to optimize temperature overshoot and stability.

Other features offer added flexibility. A single resistor sets the maximum output current to load. Add a diode to operate resistive heaters with a unipolar output current. An onboard reference voltage simplifies potentiometer control of the temperature setpoint. You can also choose to operate remotely with an external setpoint voltage. Two monitor pins provide access to the temperature setpoint voltage and the actual sensor voltage.

The HTC1500-62 has proven reliable in such diverse fields as medical, defense, communications and manufacturing. The HTC is particularly suited to applications where temperature is scanned across ambient.

Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. The standard product can be easily modified to meet your application requirements.
