Newer technology has been built into theย PTC10K-CHย 10 A temperature controller. The MPT is not recommended for new designs.
The robust MPT series circuitry achieves 0.005ยฐC temperature stability. It is a chassis mount package with cabling to the male DSub15 connector available:ย WCB101. Theย MPT10000ย drives up to 10 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar). Theย MPT5000ย drives up to ยฑ 5 A. Theย MPT2500ย drives up to ยฑ2.5 A. For evaluating the unit on a benchtop, theย MULTI-HTSK-HIย is available.
This temperature controller interfaces with virtually any type of temperature sensor. An onboard sensor bias current source can drive thermistors, RTDs, or the LM335. For current sensors like the AD590, simply bias it and drive it into the sensor input. A trimpot adjusts the Proportional Gain (P). A fixed Integrator Time Constant (I) capacitor can be custom fit to your application to optimize temperature overshoot and stability. Another trimpot adjusts the setpoint temperature. You can use a remote signal (D-to-A, or remote trimpot, for example) with the external analog input to control the operating temperature. Up to 25 V can be delivered to the load with 30 V input. Heatsinking then becomes critical and a Safe Operating Area tool is available to make sure you don’t exceed the maximum internal power dissipation of the package. Monitor pins bring out both Setpoint and Actual temperature signals. Current limit is set via a single-turn trimpot under the cover.
Theย MPT10000ย has proven reliable in such diverse fields as medical, defense, communications and manufacturing.
Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard product can be easily modified to meet your application requirements.
