The linear, PI control loop offers maximum stability while the bipolar current source has been designed for higher efficiency. The PID1500 drives up to 1.5 A for either Thermoelectrics (bipolar) or Resistive Heaters (unipolar). An evaluation board simplifies prototyping: PIDEVALPCB. Heatsinking is already provided to support operation across a -20°C to +85°C operating range.
The PID1500 temperature controller is easily configured for any design. Virtually any type of temperature sensor can be used with the PID1500and a built in switchable sensor bias current source simplifies use with resistive temperature sensors. The Proportional Gain (P) is adjustable with an onboard single turn trimpot. Use an onboard trimpot to adjust the setpoint or the Analog Input pin for remote control. Use another onboard trimpot to set the maximum output current to the load or set it with a resistor between pins 1 & 2. A switch between those pins acts as a remote enable / disable. Remove a jumper to operate resistive heaters with a unipolar output current. Two monitor pins provide access to the temperature setpoint voltage and the actual sensor voltage.
The PID1500 has proven reliable in such diverse fields as spectroscopy, defense, and medical research.
