5300-08-24 8A / 24V TECSource

The 5300-08-24 TECSource is our most powerful temperature controller. Providing 192W of TEC control, the 5300-08-24 is flexible enough to meet the demands of most temperature control applications. The 5300-08-24 supports all common sensor inputs (thermistor, RTD, AD590, and LM335), and has a 4-wire RTD mode to eliminate connector resistances.

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.

Excellent Stability
The 5300-08-24 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, the 5300-08-24 provides an excellent solution for precision temperature control.

Fully Adjustable PID
The 5300-08-24 comes with eight factory set gain settings for the temperature control loop, which are sufficient for most applications, but also offers fully adjustable PID settings, allowing you to fine tune the response of the instrument. Also, because the loop is digital and uses the temperature (not sensor resistance) as the control variable, variations in sensor sensitivity across temperature (primarily seen with thermistors) does not affect the unit as it does with analog-based PID loops.

  • 192W of TEC power
  • 0.004°C stability
  • AutoTune automatic PID
  • Bi-polar output: heat & cool
  • Thermistor, RTD, LM335, & AD590 sensors
  • 4-wire RTD mode

Integrated Fan Supply
The 5300-08-24 includes an adjustable 4.5V to 12VDC power supply for power external fans, such as those on our 240 and 260 Series LaserMounts. By incorporating the power supply, it eliminates the need for an external power supply and simplifies cabling to the mount. If you will be using this power supply, make sure you choose the 1262B or 1263B TECSource Cable, which includes the additional wiring for the power supply.

Standard Computer Interfaces
The 5300-08-24 includes both USB and RS232 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 User Interface
The 5300-08-24’s user interface is remarkably simple… so easy to use, you’ll have it up and running in no time. Unlike other instruments which rely on 7-segment LED displays and a confusing array of indicators and buttons, the 5300-08-24 instead presents the information on a high contrast VFD display in an easy-to-read format. The 5300-08-24 displays the temperature set point, actual temperature, current, and voltage simultaneously… no need to toggle though the readings like on most instruments. If you need a larger display for viewing at a distance, you can press the knob to toggle to a larger display of the actual temperature. Settings and error messages are in clear English, not cryptic codes and flashing status lights.
