The Kenwood PDS120-6 is a regulated DC power supply engineered for precision applications in testing, research, and development. It delivers 0–120 V output voltage and 0–6 A output current with 720 W total power, supported by simultaneous digital displays for real-time voltage and current monitoring. The unit combines a series-mode regulator with switching architecture to achieve exceptionally low noise: 1 mVrms ripple across 5 Hz to 1 MHz bandwidth. Transient response completes in 100 μsec, with rise and fall times of 100 msec and 150 msec respectively at full load.
