Acopian VA5H3200M Power Supply

The Acopian VA5H3200M is a linear regulated DC power supply delivering 5 VDC at 32 A, designed for applications requiring stable, regulated power output. This convection-cooled unit operates across 50–400 Hz input frequencies and supports dual input voltage configurations: 105–125 VAC standard, or 210–250 VAC with the -230 suffix option. Built with extruded aluminum construction, It has floating outputs with remote voltage sensing as standard, ensuring accurate regulation at the load.

Short circuit protection is integral. The supply mounts flexibly in 19" RETMA racks, as a 17" benchtop unit, or via threaded mounting holes on bottom and side surfaces. Optional DIN rail and wall-mount kits expand installation flexibility.
