K2 - Dual LAB Power Supply

While numerous bench power supply designs have emerged over the years, few combine all aspects of performance, flexibility, and low cost. This universal lab supply design combines exceptional current and voltage range (0-50v, 0-5A) and control with an economical modularity. At the same time, the custom heat sink and circuit board design combine to leave point-to-point wiring at a minimum, greatly simplifying the construction process. For a summary of the performance characteristics, see Specifications.

This kit is available as the hard to get components, and kit of all board mounted parts plus potentiometers, transformer, and heat sinks. The transformer will power two supply channels.
