7154-04-08 MultiSource TEC Controller

The 7154-04-08 MultiSource is a compact, four channel temperature controller for lower power applications. With 32W of TEC control and support for thermistor sensors, it is the ideal choice for high density, low power TEC applications. Each channel includes an auxiliary DC fan power supply for controlling external fans, such as those in our 207 LaserMounts.

AutoTune Automatic PID Calculation
All Arroyo Instruments temperature controllers feature AutoTune for automatic PID calculation. With AutoTune, you no longer need to fiddle with PID parameters to find values that work with your application. Simply hook up your mount, set the appropriate limits, and start the AutoTune process. The instrument will automatically calculate PID parameters that will work with your mount.


Preliminary information
This is a preliminary product specification. Initial models of the MultiSource product family will begin shipping in Q1 2018, with additional models following.

  • 4 Channel TEC
  • Shipping Q1 2018, contact factory for details
  • 32W of TEC power per channel
  • 0.004°C stability
  • Bi-polar output: heat & cool
  • Thermistor sensor
  • Compact enclosure

Excellent Stability
The MultiSource offers excellent short term and long term stability. At less than 0.004°C stability over one hour, and 0.01°C over 24 hours, it provides an excellent solution for precision temperature control.

Standard Computer Interfaces
The MultiSource includes both Ethernet and USB computer interfaces, allowing for quick and easy connection to a PC for remote operation. In addition, the TECSource’s command set is compatible with ILX and Newport controllers, allowing you to leverage any existing software you may have already developed.

Simple Local Control
While intended to be primarily operated from a PC, the display on the MultiSource allows you to locally monitor status and turn channels on and off.
