Great Power Supply Time Owned: 6 to 12 months.
I purchased one in December of 2022 to power a Kenwood 480 HX. It has operated quietly and has proven itself capable of handling the Kenwoods demands. I highly recommend it.

Excellent Switching Supply Time Owned: 3 to 6 months.
I selected the JTPS50A because of its low cost, 50-amp high current capacity and 1/4-inch termination bolts. Astron has abandoned terminal bolts on its switching supplies in favor of its own poor connector design.

It's important to have a low-resistance connection between transceivers and the power supply. Multiple terminal connections can be made using crimped ring lugs spread around the bolts. By contrast, Anderson Powerpoles at the power supply have some measured resistance no matter how well the mating connector is crimped.

I used a spectrum analyzer to measure switching noise by bringing test leads out from the supply to act as a radiating antenna. No switching spurs were observed between 160m and 6m. If needed, the supply voltage can be adjusted up to +15.5V.

The JTPS50A comes with a quiet fan but I went a step further and completely eliminated the sound of moving air by replacing it with a Noctua model NF-A6x25 FLX 12v. The retrofit to the Noctua fan was very easy. The supply stays cool even under high-current, high-duty-cycle loads.

No Noise or RF Hash Time Owned: 0 to 3 months.
This is a great switching power supply for transceivers and mobile amps in the shack. It is noise free and it delivers about 42 amps continuously. It's compact and looks great!!! You won't be disappointed with this product.

Simple, great size, high capacity Time Owned: 0 to 3 months.
I had to replace my Astron after 25 years....needed a stand alone and forget its there unit. R&L Electronics came through again, I went ahead and got the 50A unit as I can run multiple items off of it if needed. Very small, about 1x6x10 deep. Except for green on switch I don't even know its there. I loved my Aston but this is a quarter the size. No hash, noise, just works. R&L has great deal on these. de WO8USA
