The Amrel PPS-1326 is a programmable DC power supply engineered for development, testing, and integration into automatic test systems. It delivers 0–30 V and 0–3 A with selectable AC input (115 VAC or 230/240 VAC ±10%), GPIB remote programming, and remote sense compensation for load-lead voltage drop. The unit combines fine control resolution—10 mV voltage and 1 mA current steps—with tight accuracy specs (0.05% + 20 mV voltage; 0.15% + 3 mA current) and low output noise (1 mVrms/10 mVp-p voltage, 1 mArms current across 20 Hz–20 MHz).
