|I purchased this supply after surveying a number of available options. In particular, I was looking for a physically small, fanless suppy with decent overvoltage and overcurrent protection. This one fit the bill.|
The output terminals are wire push-in screw connections with tension sleeves. There are two terminals each for positive and negative output. I don't much care for these kind of connections and would have preferred an anderson power pole connector or some other beefier connection. My sole issue with the power supply has been a loose connection that caused an intermittent rig failure before I addressed the issue. Otherwise, it's been a solid performer and doesn't get hot even with prolonged transmission of digital modes like FT8.
Inside, the PC board of the supply is marked as a Mean-Well ENP-340 series power supply, The other specifications are consistent with the Mean-Well. Larger filter and electrolytic capacitors are Samxon brands (HP and SK series) rated for 105c. The remaining smaller electrolytics are Rubicons also rated for 105c.
There is a small aluminum heat sink (appx 4.25" x 1.5") that is connected via thermal interface paste to the top of the metal case. During prolonged operation, the case barely gets warm.
Overall, the build quality of the supply seems very good with quality components. There are a number of MOVs for overvoltage protection and an internal-only auto-resetting fuse. There's a voltage adjustment screw externally accessible on the back. The front has only a power switch and power-indicator LED.
This supply is rather expensive for the output, but I like the small size and silent operation.
