STJ Series TEC Drivers (Temperature Controllers)

The TEC driver is a high-performance temperature control system (air cooling) specially designed for driving laser diode (thermoelectric refrigeration chip, TEC), with high precision and high stability.It is based on the principle of Peltier effect. It has the advantages of high precision, long service life, small volume, no noise, no wear, no vibration, no pollution. The TEC driver has perfect PID control software and intelligent stepless temperature control, which can both cooled and heated. It can control by RS232 / 485 serial communication interface and communication protocol.

It can also supplies 1-2 channels of TEC control output, which can be used to control laser, medical devices, diode, infrared detectors, photomultiplier tubes, or any other devices which need the temperature control.

The TEC driver adopts the latest modern power electronic devices, high-speed microprocessor (MPU) program control technology, as well as PWM modulation, bidirectional power supply and PID regulation technology. It has excellent voltage and current output characteristics. No overshoot, no kickback, no surge and low noise when operation.

It also has over-current, over temperature and under temperature protection circuits, as well as a set of normally open / normally closed temperature alarm signal output.

The driver adopts 16 bit "8" LED, simple menu mode display, membrane button, and has friendly user interface and fault diagnosis function.

It is an excellent choice for laser equipment manufactures, research institute and personal. We used the standard PT1000 temperature sensor (platinum resistance) to have the best precision, linearity and stability.
