Overview
The 5240 TECSource is a popular temperature controller for lower power applications. With 28W of TEC control power and support for thermistor sensors (10µA or 100µA bias current), it’s still a powerful unit, and a good choice when the higher power or sensor support of the 5305 or 5310 is not needed. It also has an auxiliary DC fan power supply for controlling external fans, such as those in our 207 LaserMounts. Housed in a compact enclosure, and supporting many of the same features as the larger 5300 family, the 5240 is an excellent mix of features, size, and price.
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 5240 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 5240 provides an excellent solution for precision temperature control.
Fully Adjustable PID
The 5240 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 ogf 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.
