Radioddity PS30 Switching Power Supply – A Review


--By Robert Gulley K4PKM

Power supplies have come a long way since I started in amateur radio, and the behemoths of old are quickly being replaced with smaller, more efficient, switching power supplies.

I know, I know – those of us who have been around long before these little units became what they are today, cursed them with not-so-very-kind epithets because of the noise (read “dang blasted, infernal interference!”) generated by leaky components and poor design. Things have changed, and, as a rare example of something changing for the better, many modern power supplies are not only quiet both literally and electronically, they are easily portable and space-saving.

Enter the Radioddity PS30 Switching power supply. I asked Radioddity for the opportunity to test out this unit for review, mainly because I have had several friends get similar power supplies and they have been enjoying much success operating in various modes and bands without issue. None. Okay, that made me curious indeed. As always, I list pros and cons at the end of the review.

The unit is solid and the controls are responsive without any play. The unit sports a very nice LCD screen, allowing one to see at a glance how power is being used in volts and amps. There is a noise offset control to move a birdie should one appear on a desired frequency. That is, if you experience noise on your connected gear that you suspect is originating from the switching power supply, use the Noise-offset control to reduce it to a minimum.

There is also the ability to vary the voltage. With an adjustable 8–15V DC output (a fixed option at 13.8V for most radios) and up to 30A peak / 20A continuous current, it easily supports ham radios, CB radios, HF transceivers, and other DC-powered devices. Short-circuit and overload protection is built in via a fuse on the backside.

The unit sports two sets of Anderson Power Pole™ connectors on the front, and a set of terminals on the back that also allow 4mm banana-plugs to be inserted. Personally I like the multiple power connection options as I use all three options depending on the radio I am connecting at the time.

Reliability

For those who have been around a while you know reliability in power supplies is measured in years rather than months or days, so I cannot speak to the expected lifetime of the supply. However, in the months I have had the unit I have seen no issues with fluctuating power, noise (physical or electrical), or the controls. The unit seems well made, heavy enough to give it a sense of solid design, but not so heavy it would be an issue taking it portable, depending on your specific needs, of course.

Pros and Cons

Pros:

Small footprint
Solid Design
Multiple Connections
Adjustable controls for Power and electrical noise offset
Bright LCD Display
Quiet Fan
Detachable standard computer-style power cord.

Cons:

Front power connectors not aligned in the usual fashion. Traditional designs have the red and black connectors next to each other rather than above and below. Not really a big issue, but some folks have reset them (I would check before doing so to ensure that it does not void your warranty!)
Update from Radioddity: The power connector layout has been refined in our current stock to ensure a more intuitive, standard user experience.

Conclusion

I am impressed with the power supply and see no reason not to recommend it. With the cost of linear power supplies having skyrocketed over the last few years, modern switching supplies have much to offer, and the price makes them very appealing. Frankly, even if you had to replace one after a few years, you still would not come close to the cost of a linear supply. Radioddity definitely has a nice offering here in the PS30. 73, Robert K4PKM

Interesting the noise control , I have never Seen bevor, but thaught about it by changeing the switching frequency.👍

Being a product reviewer for Radioddity, one of my biggest problems is mislabeled hardware. Power supply buying is a tedious process and having a reliable PSU is key to your gear working successfully. That said, this product is mislabeled. It should be advertised as a 20A PSU. 20A isnt very large and most mobile radios need 20A to run 50W when rag chewing. The label PS30 is incorrect. If the device is rated at 20A you are at 100% capacity.

You never want to run maximum 100%.
15v at 20A is 300W
12v at 20A is 240W
8v at 20A is 160W

So, I would run this at 10A continuious to have it last and not burn out.
