    I bought the 24 VDC power supply (https://www.amazon.com/dp/B00RUUSKS2/ref=cm_cr_ryp_prd_ttl_sol_0) and it appears to have worked well while I had it powered on. I am drawing 2A from it, but shut it off after a few minutes because the NTC thermistor (labelled NTC 5D-9) near the input is very warm (73C measured with an IR camera). Is it normal for this part to be this warm when drawing about 2A ?

    Also, for reference, I am powering this with 120V AC
