The 286 TECMount comes standard with an integrated fan for additional cooling capacity. When used with the Arroyo Instruments TECSource temperature controllers, no additional power supply is needed to power the fan, or use a standard external 12V DC power supply when connecting to other temperature controllers.

TECMount User’s Manual · Page 5 Bolting to an optical table This configuration is very similar to the one above, but instead of the feet, you will use the MB-286 base. Start with the MP-2.00 posts, threading them into the four 8-32 holes on the bottom of the fixture.

The 286 uses a high volume fan for cooling of the heat sink. For full performance, you must place the sides and bottom of the 286 at least 2” away from any other surface, or airflow will be constricted. If you are using an Arroyo Instruments TECSource temperature controller, the...

Mount setting in the menu to either 286 or 286-150, depending on which mount type you have, and the 5300 will be automatically configured for the mount. Where possible, we recommend the use of Arroyo Instruments TEC cables. When connecting to a 5300 Series TECSource, use p/n 1262-17W2.
Page 8 · 286 TECMount User’s Manual Mounting Plates The 286 TECMount is available in a standard bread board configuration with M3 holes on 10mm centers. Custom versions of the cold plate are available, contact the factory for details. Your 286 may be configured with a custom mounting plate, and if so, this manual should be accompanied by drawing for your plate.

Page 12 · 286 TECMount User’s Manual Using the Thermistor on Standard Versions The standard version of the 286 LaserMount is equipped with a 10kΩ negative temperature coefficient (NTC) thermistor, specifically, the BetaTHERM 10K3A1. A thermistor works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’).
The coefficients for the BetaTHERM 10K3A1 thermistor are: A = 1.12924x10 B = 2.34108x10 C = 0.87755x10 These are the default coefficients for Arroyo Instruments temperature controllers. Using the RTD on 150°C Versions The 286-xx-150 LaserMount is equipped with a RTD sensor with a 0.00385 Ω / Ω...

Page 14 · 286 TECMount User’s Manual For the Arroyo Instruments controllers that support RTD sensors, the default coefficients are different for this mount. They must be changed to use the 0.00385 Ω / Ω / °C curve, which has the following coefficients: A = 3.9080x10...
