The Topward TPS-4000 is a bench top triple output power supply. Voltage outputs may be electrically connected for tracking. The two main power supplies in the TPS-4000 have four meters for monitoring output voltage and current. Each of the power supplies is also equipped with independent controls for use when the unit is not being operated in the tracking mode. The remaining power supply has a fixed 5 volt 3 amp output.

The TPS-4000 may be used in many applications in schools, laboratories, and commercial engineering and testing departments, as well as with the advanced hobbiest.
