![]() ![]() HAP heaters typically are clamped or factory laminate to heat sinks, but can be applied using PSA at the cost of lower maximum temprature ratings. With UL component recognition: -45 to 220C (-50 to 428F) Resistance tolerance: 10 or 0. Minco's unique ability to manufacture these heaters has prompted success in many high-temperature applications worldwide. Heaters can include thermostats, temperature sensors and cutouts, wiring harnesses, connectors, and controllers RoHS compliance Temperature range: -45 to 235C (-50 to 455F). ![]() Alternatively, use an N-channel logic-level mosfet - there are many suitable ones, including STP40NF10L.HAP All-Polyimide heaters are a high performance alternative to Minco's standard polyimide heaters, allowing higher temperatures and watt densities. I wouldn't use a BC337 to switch these currents from an Arduino, but the ZTX851 would be OK if you limited the voltage to 50-55V (its Vceo rating is 60V). The current would be about 500mA 50V or 600mA 60V. If so, could we still use an NPN transistor and perhaps specifically those models above? Will we also need a Solid-state or non solid state relay? Also, do you see us needing anymore components? Thanks!! One for the arduino (possibly a wall adapter or 12V battery), and a much larger one to power the Kapton heater (perhaps with 50 or 60V capacity). Therefore, it seems like we'll need 2 power sources. It seems like we can use an NPN transistor (BC337 or ZTX851) with 24V, but I don't believe we can get up to 150F with only 24V. If you use a thermocouple, then you must make sure that the thermocouple itself has long enough wires to reach the breadboard, because you cannot extend the thermocouple wires without messing up the cold junction compensation. Therefore the thermocouple will be great to get a temperature reading from a distance.Īlmost any temperature sensor can be read from a distance, including semiconductor sensors such as DS18B20 and LM34. We are going to go with the K-type thermocouple because we cannot have the breadboard in the same room as the platform. What is the best way to get a high voltage to power this Kapton heater without frying the Arduino Uno? Any idea if I need a solid state relay and if so, what kind? Do I need a shield? Budget is not a concern - more focused on a simple solution. Seems like I need some sort of amplifier to increase the power signal from the Arduino. Hoping to use about 50V (24.75W, 0.5A) to heat up the platform in a reasonable time. If I use epoxy to mount the Kapton heater to my platform, it can crank up to ~240F! However, I think I need a lot more than 12V input to achieve a high temperature. With the Kapton heater I have (model: HK5369R101L20A), the resistance is 101 ohm and yields 1.43W at 12V (current = 0.12A). English Metric Element Code, PD Temperature Range, -50 to 260C (-58 to 500F) Pressure Rating, 7,000 psi (483 bar) at 21C, reducing to. Buy Mica Thermofoil Heaters from, your online source for Minco products. ![]() Therefore I believe I will need either a MAX31855 or AD595 - anyone have a preference? I would like to use K-Type thermocouples as my temperature sensor. Use a thermocouple to read the temperature of the platform and have the temperature displayed on an LCD monitor. Let the user set the temperature within this given range. Project Goal: Heat up a 1/2x3x4" aluminum platform anywhere from room temperature to 150F using a 1x2.5" Kapton heater and an Arduino Uno with PID control. I'm new to Arduino, but have some experience with C++. ![]()
