Specifications Top

This compact switching power supply offers the unique capability of providing 100W output in any volt/amp combination within its 60V and 5A limits. By providing a wide range of power combinations, fewer supplies are required, saving money and valuable bench space. When the maximum of 60V is selected, the maximum current output is 1.66A. At the 20V setting, the maximum current output is 5A. Any volt/amp combination between these limits is achievable, as long as the 100W max output is not exceeded.

      A fine lab grade power supply for the advanced hobbyist

      Overall: 5 out of 5
      Top 25 Contributor

      This was my first “lab grade” power supply purchase. I bought it on sale for $224. This unit may seem initially expensive, but I feel that it is worth every penny. The output control is very smooth and the settings do not drift after releasing the control. The control can easily be locked with a single button, preventing accidental over-voltage issues. One of my favorite features is the ability to limit the absolute maximum voltage and/or current output settings. This will pay for itself the first time you accidentally twist the control too far and destroy your circuit/device. I have mine set to a maximum 14.4 VDC when working on mobile VHF rigs and it works like a charm. This unit has up to 100 programmable presets available. Quite frankly, I have never used them as it is fairly easy to setup whatever output you desire in just a few seconds. The output voltage and current seem to be quite accurate when compared to two Fluke volt meters. It also has a 0.01 V/1 mA display resolution, which I really like. The inside of the unit appears to be well built and made to laboratory-grade standards. But I expect nothing less from B&K Precision. The only minor issue worth mentioning is the lack of a ground strap between the negative and chassis ground binding post. I have worked with a fair amount of high-end test equipment over the years, and this is one of the few times that I have not seen such a strap provided . Yes, it is easy to just connect a wire between the posts, but would it have cost all that much extra to provide a nice looking $0.10 piece of copper? Overall, I really like this unit and find myself using it all of the time. I would highly recommend purchasing this unit if you need a high quality, laboratory grade power supply.
