Overview

First off, let's talk about what this device is. The Pyramid PSU990KX is essentially a benchtop power supply that converts AC to DC, providing a solid and consistent 13.8 volts of DC power at up to 7 amps with a continuous 4.5 amps. It's perfect for powering devices like CB radios, scanners, HAM radios, and a whole plethora of other electronic equipment. The dual USB ports are a nice touch, allowing you to charge phones or other USB-powered devices alongside whatever you're working on.

Design and Build

Out of the box, the first thing you'll notice is the robust and compact design of the PSU990KX. It's not flashy or over-the-top in any way, which I personally appreciate. The dimensions are modest at 7.7 x 4.9 x 2.8 inches, and it weighs just a tad over 5 pounds. This makes it quite portable for a bench power supply, and it can easily be moved around your workspace or stored away when not in use.

The casing is made from a durable metal that feels quite rugged. I've accidentally bumped it off my desk once (don't ask), and it survived without a scratch. The front panel sports a simple setup with a power switch, a couple of LED indicators, and the aforementioned dual USB ports alongside banana plug terminals. There's also a cigarette lighter socket, which is a great addition if you're working with portable devices that require such a connection.

Performance

This is where the Pyramid PSU990KX truly shines. In terms of performance, it provides a constant and reliable source of power that makes it ideal for testing and powering a variety of electronic devices. I've used it with CB radios, tested a few Arduino projects, and even powered a small LED strip setup, and it hasn't faltered once.

The power conversion is steady and efficient, thanks to its regulated linear design. The advertised 7-amp capability is spot on, although I generally use it at the continuous 4.5 amps for most of my projects. The voltage remains stable under load, which is crucial when you're working with delicate electronics that require precise power input.

Dual USB Ports

The dual USB ports are a standout feature for me, as they add an extra layer of utility to the power supply. Whether I need to charge my phone or power a USB-powered device, these ports have been incredibly handy. They output a consistent charge and have been reliable with every device I've connected.

Cigarette Lighter Socket

The inclusion of a cigarette lighter socket is another thoughtful addition. This allows you to power up devices that usually require a car's power outlet. It's not something I use daily, but having the option is definitely a bonus, especially when working with car-related devices or testing portable gear.

Safety Features

Safety is paramount when dealing with electronics, and the Pyramid PSU990KX doesn't skimp in this department. It comes equipped with built-in electronic overload and short-circuit protection. This feature gives me peace of mind knowing that both I and my devices are protected from any unexpected electrical mishaps. The unit also features a heatsink to dissipate heat effectively, ensuring it doesn't overheat during prolonged use.

Ease of Use

One of the things I appreciate most about the PSU990KX is its simplicity. It's a plug-and-play device, meaning you don't need to be an electronics expert to use it. The banana plug terminals are clearly marked, making it easy to connect your devices correctly. The LED indicators provide immediate feedback on the power status, which is always a good thing to have when working with power supplies.

Intended Use and Versatility

While this power supply is marketed primarily for use with radios and similar equipment, its versatility cannot be overstated. I've found it invaluable for a wide range of applications, from hobbyist electronics projects to more professional setups. It's become a staple on my workbench, and I imagine it would be just as useful in a garage or repair shop setting.

Comparisons and Alternatives

When compared to other power supplies in its class, the PSU990KX holds its own quite well. Its compact size and dual USB ports give it an edge over some competitors that might be bulkier or lack such features. While there are other models with higher amperage ratings, for most home and hobbyist applications, the 7-amp capability is more than sufficient.

In terms of price, it's reasonably positioned in the market. You're getting a lot of features and reliability for the cost, which makes it a great value purchase. If you're looking for something with even more power output, Pyramid does offer other models, like the PS15K.5, but for most users, the PSU990KX will likely hit the sweet spot.

Final Thoughts

So, would I recommend the Pyramid Universal Compact Bench Power Supply? Absolutely. It's a reliable, well-built, and versatile power supply that caters to a wide range of applications. Whether you're a hobbyist, a professional, or just someone who needs a dependable power source for various devices, this unit will serve you well.

The combination of its compact design, dual USB ports, and robust safety features make it a standout choice in the world of bench power supplies. It's become an indispensable part of my toolkit, and I have no doubt it will be the same for anyone else who gives it a try.

If you're on the fence about getting a bench power supply or upgrading your current setup, I suggest giving the Pyramid PSU990KX a shot. It's a purchase you won't regret.
