The Rigol DP821A is a dual-channel programmable linear DC power supply delivering 140 W total output power. It combines independent high-voltage and high-current outputs in a single benchtop instrument, serving R&D labs, manufacturing test floors, and system integration environments where precise, stable power sourcing is essential. Channel 1 spans 0-60 V at 0-1 A; Channel 2 operates at 0-8 V with 0-10 A capacity. Low noise and tight regulation make it suitable for sensitive analog circuits, power device characterization, and automated test sequences.
