About This Instrument
The Vartech PPS 3005-3 is a triple-output programmable linear DC power supply. Two main variable channels deliver 0–30 V / 0–5 A each, and one auxiliary channel provides selectable fixed output of 2.5 V, 3.3 V or 5 V at 3 A — covering all common digital logic supply rails. A USB PC interface (supports LabVIEW) enables remote control and automation. Features include 5-digit (V) + 4-digit (A) LED displays, 4 memory sets, panel lock, auto CV/CC, high resolution (100 mV / 10 mA) and comprehensive protection. A lower-current variant (PPS-3003-3, 30 V / 3 A for Ch 1 & 2, 7.5 kg) is also available in the same chassis.
