HTCEVALPCB Evaluation Board

The advanced and reliable circuitry of the HTC series achieves 0.0009°C temperature stability. Its small, low profile package is ideal for designs with space constraints. The linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency.The HTC 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 your 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 PTC-CH Series Chassis Mount Temperature Controllers deliver the precision performance and long-term reliability you expect from a Wavelength Electronics temperature controller. PTC-CH Series controllers are found in such diverse applications as particle and droplet measurement, manufacturing machine vision systems, biomolecular interaction analysis, and more. The PTC-CH controllers operate from a single power supply between 4.5 V and 30 V, and a selection of models allows you to optimize the current output level for your application. The linear bipolar controller drives a Peltier thermoelectric cooler or a resistive heater, and the chassis-mount package integrates easily into OEM applications.PTC-CH controllers interface with a variety of temperature sensors, and the bias current is adjustable in order to maximize controller sensitivity and stability for your application. The compact chassis-mount design simplifies heatsinking and requires minimal space. PTC-CH controllers are quick to configure for your prototype project, and there are no surprises when it's time to integrate the controller into the final design. Practical Features For Real-World Conditions Built-in features make your product more robust to real-world operating conditions and minimize your electronics overhead: If the optional remote temperature setpoint signal is lost, the controller defaults to a standard "safe" temperature setpoint (25ºC when a 10 k Ω thermistor is used). The safe temperature can be changed at the factory; call for details. An on-board trimpot is used to set the output current limit to prevent over-driving the TEC, and helps protect your load from thermal runaway situations. Proportional gain is easily adjusted with an on-board trimpot. Low temperature coefficient design remains stable across a wide range of ambient conditions.When used with Wavelength's laser drivers, such as the PLD Series, these temperature controllers provide stable and reliable performance that sets your system apart from your competitors' and keeps your customers satisfied.
