First Impressions

Right out of the box, the Pyramid PS9KX makes a solid first impression. The unit is compact, measuring just 7.5 x 4.9 x 3 inches, and it weighs in at a manageable 4.4 pounds. Its black finish gives it a sleek look that would fit right in with any home lab or workshop setup. The build quality feels robust, and the device seems durable enough to withstand regular use.

Design and Build

One of the standout features of the Pyramid PS9KX is its linear/regulated power supply design. This ensures a reliable and consistent source of DC voltage, which is crucial for sensitive electronic equipment. The unit is equipped with universal hardwired screw-type connection terminals, making it compatible with a wide range of devices and components. This flexibility is a significant advantage if you frequently test different equipment.

The power supply also includes a 12V car cigarette lighter socket, which is a nice addition for those who need to power automotive equipment. The unit's rugged housing construction, combined with a cabinet heatsink, is designed to dissipate heat effectively, preventing the device from overheating during prolonged use.

Performance and Usability

Performance-wise, the Pyramid PS9KX does not disappoint. It provides a constant current of 5 amps with a surge capacity of 7 amps, which is more than sufficient for most hobbyist applications. The power output is a steady 13.8V DC, and the input requirement is 115V AC at 60Hz with a power input of 70 watts.

The device's plug-in operation is straightforward, and the power supply is equipped with a power ON/OFF switch for convenient control. I found the power conversion to be quick and consistent, eliminating the need for external batteries or additional power sources. This is particularly useful for those who may be new to using bench power supplies and want a hassle-free experience.

Another significant feature is the built-in electronic overload and short circuit protection. This added layer of security ensures the safety of both the operator and any connected devices, giving you peace of mind during operation. The unit is also fuse protected with an auto-reset function, which is a great safety feature that prevents damage in case of power surges.

Cooling and Noise Level

A built-in cooling fan is part of the design, which helps to keep the power supply cool during operation. I noticed that the fan operates quietly, which is a big plus if you’re working in a quiet environment or need to focus without being distracted by loud fan noises.

Practical Applications

The Pyramid PS9KX is incredibly versatile. I tested it with a variety of devices, including a CB radio, a ham radio, and a mobile phone, and it performed admirably across the board. The universal compatibility with different devices makes it a valuable tool for anyone who needs a reliable source of DC power for testing and operation.

For hobbyists and DIY enthusiasts, this power supply is a dream come true. Whether you're working on model trains, RC cars, or other electronic projects, the consistent power output makes it easier to test and run your devices without worrying about fluctuations in voltage or current.

It offers excellent value for money, especially when compared to other power supplies in its class. The safety features alone make it worth the investment, not to mention its versatility and ease of use.
