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 HTC3000 drives up to 3.0 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar).

The HTC1500 drives up to ±1.5 A. An evaluation board simplifies prototyping: HTCEVALPCB. A heatsink that mounts directly to the HTC is available: HTCHTSK. The HTC3000 is designed for 0.031″ thick printed circuit boards (PCBs). The HTC3000-62 is designed for 0.062″ 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 HTC3000 has proven reliable in such diverse fields as medical laser control, 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.

FAQ1086: Do you have a chart indicating the relationship between the resistance of the setpoint and the current of the thermoelectric?
FAQ1097: We are building a prototype laser cooling system that needs to control the temperature of two thermoelectric coolers (Melcor part: CP1.4-127-10L) connected in series. Each TEC has the following operating specifications: Qmax = 33.4 Watts Delta Tmax = 68°C Imax = 3.9 Amps Vmax = 15.40 Volts Module Resistance = 3.44 Ohms Will the HTC3000, 3.0 Amp product and its evaluation board be a suitable controller for this application since the TECs won't really be driven too hard (except maybe at start-up)? Would a 24 V power supply be sufficient to drive these TECs if they were connected in series?
