If so, can you suggest some part numbers? I am assuming these are too light for the duty they are trying to perform and would datasehet to try and replace them with heavier Mosfets.
The unit is relatively new and hasn’t seen much use. So when carrying 14 amps, it will be dissipating about 78 watts of heat. Don’t forget to check the caps. This means that the the junction is.

Ken1 Member Feb 28, Otherwise you’ll need to resort to cold water or refrigerated cooling. I am assuming these are too light for the duty. Welcome to our site! Often the input FETs are just the weak link and something else is the real culprit. Electrolytic caps are a prime suspect. Replacement Transformer Started by ncag Today at 7: Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
What are you doing with it? I am attempting to repair a Powermax PM power supply unit. Tc is case temperature, not ambient.
So it will only handle 14 amps continuous if the case is kept at 25C all of the time. Doable in a cryogenics lab, but not really a practical value for most real world applications. They are mounted on dtaasheet large aluminum heatsink and the unit also has a cooling fan.
Datasheets, Manuals or Parts. But if increased current capacity is your only goal, there is a big trap you need to look out for. Ken1 Member Mar 1, We need to recalculate everything again based on the new info.
Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at That’s way too low as this power supply is powered by VAC which is fed through a bridge rectifier, then filtered with an uF V capacitor then fed to the Mosfets through the SMPS transformer.
The unit belongs to a neighbour and he said it just quit working; he doesn’t know if it was running hot before it quit.
As Tony points out, there will usually be some other parameter that changes along the way. This is determined by the V-I slope of the driver and RdsOn of the switch. Take a look at this one. Forums New posts Search forums.
