Acopian N020HP1.5

The Acopian N020HP1.5 is a single-output AC-DC power supply delivering regulated 20 VDC at 1.5 A (30 W) from standard 105–125 VAC input. The unit features remote voltage adjustment via external 1K potentiometer, screw terminal connections, and threaded mounting holes for fixed installation. Line and load regulation both hold ±0.05% or 5 mV, with transient response of 300 µS to ±1% and automatic current-limiting protection.

Remote sensing compensates for up to 0.5 V drop per output line. Output is floating and can be grounded or floated to 300 V above ground. The supply operates across –10 to +60°C ambient without derating, handles 90–265 VAC universal input configurations, and meets TAA compliance and ISO 9001 certification.
