Acopian P020HP1.5

The Acopian P020HP1.5 is a single-output AC-DC power supply engineered for precision voltage and current regulation in laboratory and industrial test environments. This unit delivers 0–20 VDC output at 1.5 mA with exceptional line and load regulation, floating output architecture, and comprehensive short-circuit protection. The supply operates from 105–125 VAC, 50–400 Hz single-phase input (230 VAC option available) and accommodates ambient temperatures from –10 to +60°C without derating.
