COLLENCE 3D Printer Heating Controller 30A Heatbed MKS MOSFET for Extruder MOS Module

I've been using this on my Tronxy X5S inline for the headbed, and it's been doing a great job. The fins get to about +10°F from the ambient temperature of the room, not enough to notice most times. It cut my bed heatup time to under half the previous time, and should be fine to upgrade to 24V when I update the bed power supply down the road.

This is the same as the TriGorilla one I put in an earlier printer. This one went into a Monoprice Maker Select Plus printer.1st this board is large. I had to trim about a 1/4 inch off the circuit board to get it to fit in the Plus chassis. But with the extra wiring added to get the cables to reach, it was quite easy to wire up. It also takes a lot more current than my heat bed can produce to overwhelm it. It should be a good protection instead of the old connections running all current through the motherboard. Ive run this printer and MOSFET up to 100 degrees C and it showed no sign of problems providing the current necessary. Works on either 12V or 24V which means its perfect for most 3D printers. Much better than the BIQU one I looked at. It was however one of the more expensive MOSFETs I looked at but is worth the price.Update 03-18-18:I have smelled something a little smokey for the last few days around my 3D printers but couldn't determine the source. 03-17-18 The heated bed on my Monoprice Maker Select Plus was no longer warming up. I troubleshot the printer and found the board and heat bed and wiring OK. But this MOSFET has gone bad and was the source of the smell. It had voltage coming into the board from the power supply and motherboard but would not switch on. I removed it and redirected the heatbed wiring back to the original motherboard connector. All is now working again. I will have to get another MOSFET. I reduced the rating to 2 stars because it lasted less than 5 months.
