The Kikusui PAN35-20, DC Power Supply, is a high-performance, highly reliable DC power supply unit featuring regulated variable voltage. This unit is suitable for use in a range of fields including research and development, quality control, and production. The Kikusui PAN35-20, DC Power Supply, consists of a pre-regulator using FETs and a series regulator using power transistors, providing the high-quality output characteristic of the latter as well as the low power-source harmonic distortion of choke input type phase control. To achieve the high reliability and safety, components of sufficient derating and long-proven mounting techniques are used throughout. All models are carefully designed and furnished with over voltage protection (OVP) and various safety functions.
