Acopian K20D50

The Acopian K20D50 is a regulated DC power supply engineered for industrial and laboratory applications demanding precision voltage stability and reliable current delivery. It combines electronic current limiting with automatic recovery protection, transient response of 50 microseconds, and remote voltage sensing to maintain output regulation across the load. The unit accommodates single-phase AC input of 105–125 VAC at 50–400 Hz and features floating or dual output configurations with temperature coefficients as low as 0.015%/°C.
