2pcs PTC Heating Element 5W-50W AC DC 12V 220 Degree consistant Temperature Ceramic Thermostatic

2pcs PTC Heating Element 5W-50W AC DC 12V 220 Degree consistant Temperature Ceramic Thermostatic

Q: Shows a 5 - 50 w power consumption. does that mean they draw max w at start up and then ramp down as they reach max temp? if not please explain

Initially these PTC heating element will draw low current <1 amp for a few seconds and then they will draw nearly 4.5 amps for about 10 seconds and stabilizes to about 2 amps at maximum temperature. To make this more manageable I found ramping the voltage up to 12VDC from 9VDC keeps the current below 3 amps at all times but does increase the time to get to full temperature (<40 seconds) . You can do your own voltage profile to see what fits your application best.

Q: How many amps does does one unit draw?

0.9A-4.5A-2.0A is the current swing.

Q: If I power these a limited current 12v power supply (lets say 500milliamps) will that limit the temperature or will it simply not function?

These should just limit the temperature available with lower amperage. These type of devices should be able to vary the temperature based on the current provided. I have not put these in service yet, but that is what I am expecting while using these as a heater when combined with heat sinks.

Thumbs up

Exactly as advertised. Worked as it should. Would buy again.

Not Temperature Limiting - Make Sure You Account for Max Heated Temperature!

If you want to limit the maximum temperature, these will not (no adjustment). They will heat to the rated temperature. I was using to heat air coming into an analyzer. However, the devices will produce a slight degradation smoke that is enough in my case to throw off the readings in my application.Probably good for heating anything that will hold up to the maximum temperature. These are essentially raw heating elements, and should be used accordingly.

Voltage identification

These work good. Did not see a UL listing on these. Or a voltage rating marked on the unit or even the packaging.

Thermostatic is accurate.

I bought these because I wanted to create a small thermostatic heating chamber. I have done some testing and they seem to cap out closer to 390°. I have yet to test a situation where I create a conduit to direct the heat and a form of insulation to keep the heat from escaping my desired area.Slightly unfortunate that it requires a separate power source that's not included. I was able to find the appropriate things to make it so I could plug it into a USB
