Kikusui PAD35-20L

The Kikusui PAD35-20L is a DC power supply delivering 0–35 VDC at up to 20 A for electronic testing, development, and manufacturing applications. Output voltage is continuously adjustable via a 10-turn potentiometer, with line regulation of 0.005% + 1 mV and load regulation of 0.005% + 2 mV ensuring stable operation across varying conditions. The supply incorporates a thyristor preregulator and series regulator power transistor with choke input circuit, minimizing harmonic distortion and maintaining output ripple and noise below 3.6 mV rms. Transient response is faster than 50 µsec for 5–100% load changes.
