ATTP1A is a temperature plate assembly, which can be also called cold plate. This assembly includes a TEC module, a TEC controller, an evaluation board of TEC controller, a fan, a heat sink and a thermistor. This temperature plate assembly is designed and used to evaluate TEC controller, TEC module or heat sinks. It can also be used to stabilize the temperature of the target objects for scientific experiments.(more)

TEC controller can also be called Peltier controller, since it is used to driving Peltier modules, which is also called TEC modules. TECA1-xV-xV-D has high efficiency, more than 90%, and high stability, 0.01°C. This TEC controller has a compact size, which saves valuable spaces for systems.(more)

TECA1-xV-xV-DAH TEC controller is designed and applied for driving Peltier coolers with high stability. This TEC controller is the updated version of TECA1-xV-xV-D, since it has a higher precision.(more)

TEC controller TEC5V6A-D is designed to drive thermoelectric cooler, which is also called TEC module or Peltier cooler. TEC module can heat up or cool down target objects by applying currents of different direction, and has been widely used in temperature related applications.(more)

TEC module is also called thermoelectric cooler or Peltier cooler, which can generate heating or cooling thermal power when an electric DC current is applied at different directions. Current direction determines heating and cooling. There are two ceramic plates on both sides of TEC module, and when the current flows in one direction, one plate is heated up while the other one is cooled down. When the current direction reverses, the two plates will reverse thermal polarity accordingly. TEC modules can be used to keep diode laser working at a constant temperature. TEC controller TEC5V4A-D is designed and used to drive TEC modules.(more)

ATFC106D digital TEC controller assembly is the updated version of the old ATFC105D, which has stopped production now. As shown in the photo below, there is a LED display and a panel for operation. In this panel, you can set different parameters and monitor different status by the LED indication.(more)

This noise measurement amplifier, ATNMA2, is designed for testing ultra low noises such as nanovolt or microvolt noises that cannot be detected by oscilloscopes. When it detects the noise signals, the noise measurement amplifier amplifies the noise to magnifications, 3,000×, 10,000×, 30,000×, 100,000×, 300,000×, 1,000,000×, 3,000,000×, according to different requirements. There are three noise measurement bandwidths: 0.1Hz ~ 10Hz, 0.1Hz ~ 1kHz, 0.1Hz ~ 100kHz.(more)
