It stays cool and is RF-quiet

Using it for ham radio. My older linear supply becomes rather hot after a 15min CW (morse) chat. The Samlex SEC 1223 is a switcher and remains cool through 30min at full power where my transceiver draws 20A during "key down". Then the fan comes on so I can go on without it overheating. The fan noise is in my opinion very tolerable, just a strong air rushing but no buzzing sound. It would be nice if it came on gradually but no big deal.

Most impressive: It is a single-layer board built around the really old TL494 chip. Yet ... no RF noise that I could find! Hat's off to the designer. Read full review

The parts kit is fine a bad part can happen. Overall satisfied.

The item is not better than expected, because one mosfet Q1 was defective. I ordered another one and now the power supply works fine.

good tech in there

Nice power supply. I haven't had any particular problems, but if you're
a Ham you might want to consider a model you can tune the birdies
away from your frequency with.

Excellent kit, but you may need more parts

This kit replaces all of the commonly failed parts in the power supply, however, it does not include the 680uF 200v caps or R17, which is a 1.5 kOHM resistor that feeds 24 volts to the PWM control IC. If you install this kit and the voltage is still jumping around and you hear a slight rattle from the transformer, check for 24 volts on Pin 12 of the IC and R17. Replacing R17 should fix the problem.Read full review

Fix a $100 power supply for $20

This repair kit usually restores Samlex power supplies to service all by itself but be aware that a power thermistor also needs to be replaced sometimes. After that, this kit fixed it. I also installed a 16 pin IC socket to make future repairs easier.Read full review

Small handy PS for my Yaesu FT-891

I use the SEC-1223 on my yaesu FT-891 and it works just fine without any problems. Have'nt used the radio for long periode of time so I kan not verify that it will work flawless under such circumstances.Read full review
