Looking at the below product from droc. I have a 54 volt power supply that fluctuates to 59 volts that i need to regulate down to no more than 57 max.  The challenge is these are outside in arizona in a water tight container, there is a fan but it gets hot. Temps will reach estimated 120 potentially as 120f.   will these devices stay running that hot or do you have another device that would work better?
