The TED4015 is a high-performance digital temperature controller designed to drive thermoelectric cooler (TEC) elements with currents up to ±15 A. It supports most common temperature sensors and can be adapted to different thermal loads. The TED4015 can be fully controlled via its robust, SCPI-compatible USB interface. The digital PID control offers an auto PID setting function or separate control of the P, I, and D parameters. The TED4015 boasts excellent temperature stability of 0.002 °C within 24 hrs, enhanced safeguard features, and error indicators, making this device ideal for cooling very sensitive devices where high stability, reliability, and precision is required.

Compared to our TED200C Temperature Controller, the TED4015 offers a wider TEC current range plus additional features like full digital control, easy auto PID setting, constant TEC current mode, set temperature protection, TEC voltage measurement, and adjustable temperature window protection. The TED4015 also offers silent operation.

Adaptability to Different Thermal Loads

The TED4015 can easily be adapted to different thermal loads by a digital PID loop. The P (proportional) gain, the I (integral) offset control, and the D (derivative or differential) rates can be individually adjusted by the user or by the auto PID function. With optimum PID parameters, the settling time for a temperature change of 1 °C for a laser mounted in our LM14S2 Laser Diode Mount is less than 2 seconds.

Supported Temperature Sensors

The TED4015 temperature controller supports almost all common temperature sensors. A sensor selection in the Temperature Control Menu allows the use of thermistors up to 1000 kΩ, the use of a temperature sensing IC (such as the AD590) or the use of platinum RTD sensors. The temperature can be displayed in Celsius, Fahrenheit or Kelvin. For thermistors, two temperature calculation methods can be selected: Steinhart-Hart or exponential. The maximum control range is -55 to 150 °C, limited by the rated temperature range of the connected sensor and thermal setup.

Enhanced Security Features

The TED4015 is designed for maximum TEC element protection and stable as well as reliable operation. An adjustable TEC output current limit prevents the controller from overdriving the TEC element. This limit can be set from 0.1 A to the current range of the controller. Adjustable temperature limits and the temperature window protection provide alerts if the temperature of the TEC element exceed certain values.

The system indicates the presence of an incorrect or missing temperature sensor and a bad connection between sensor and controller by an LED on the TEC "On" key and an audible warning signal. The TEC current is automatically switched off if an error occurs.

Temperature Monitor Output

The TED4015 provides a monitoring signal proportional to the difference between actual and set temperature. An oscilloscope or an analog data acquisition card can be connected directly to the rear panel BNC connector to monitor the settling behavior with different thermal loads.

Companion Products

Our LDC200C Laser Diode Controllers are ideal companions for the TED4015. When combined with our TEC laser mounts, the TED4015 can achieve a thermal stability of 0.001 °C. This temperature stability is required for applications like laser diode wavelength tuning and atomic absorption cell spectroscopy.
