The Micronta 22-121 is a linear regulated dual-tracking DC power supply engineered for bench testing, circuit development, and laboratory environments. This dual-output instrument delivers independently adjustable or tracking-coupled voltage outputs, each capable of 0–15 VDC at up to 1 A. Individual voltage control potentiometers govern each channel, while selectable tracking mode simplifies applications requiring matched output voltages. Built-in current limiting provides load protection, and a metal chassis with passive cooling supports extended operation in laboratory settings.
