Connects to the control switch (trigger wire) supplying 24V power to activate the internal electromagnet.

If you are troubleshooting a specific broken power supply unit, let me know:

"F4901" is also listed as a manufacturer part number for certain Dell M4040 motherboards Schematic Resources

The most prominent electronic component matching the "4901" designation in power applications is the NTMFD4901NF Dual N-Channel Power MOSFET produced by onsemi.

This is the core of the schematic, handling the bulk of the 11A current.

: Often used as a co-packaged power stage solution for point-of-load system rails.

: For a more complex Switch Mode Power Supply (SMPS) schematic delivering 24V DC, you can view the SMPS Power Supply Design on Instructables .

(0.8 mm² to 0.5 mm²) is sufficient since the coil current is negligible. Circuit Protection (Fuse Rating) Always fuse the input line matching Pin 30.

Set your DMM to DC Voltage. Measure between Pin 30 and Ground. It must read a steady 24V. If it reads 0V, check your inline fuse.

Because "F4901" appears to be a specific manufacturer's series code (likely ), you will find the official datasheet on their website.

While a "free" standalone schematic file for a specific 24V board is often proprietary, you can find reference designs for these MOSFETs in power supply and motor driver applications:

With the relay clicked "On", test continuity between Pin 30 and Pin 87 . The resistance should be near
