MPT Series

Newer technology has been built into the PTC Series temperature controller. The MPT is not recommended for new designs.

Additional information

  • Size: 3.55" x 3.5" x 1" chassis mount (MPT1000 = 3.55" x 5.5" x 1")
  • Linear Stability: 0.002°C
  • Selectable sensor bias current
  • Adjustable current limit
  • Supports Thermistors, RTDs, IC sensors
  • Remote analog setpoint input

The robust MPT series circuitry achieves 0.002°C temperature stability. It is a chassis mount package with cabling to the male DSub15 connector available: WCB101. The MPT2500 drives up to 2.5 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar). The MPT5000 drives up to ± 5 A. The MPT10000 drives up to ±10 A. For evaluating the unit on a benchtop, the MULTI-HTSK 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 28 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.

The MPT2500 has proven reliable in such diverse fields as medical, defense, communications and manufacturing.
