Features The PAN-A Series is a high-performance, highly reliable DC power supply unit featuring regulated variable voltage. These units are suitable for use in a range of fields including research and development, quality control, and production. The PAN-A Series 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. Low temperature drift Quick transient response Low ripple noise voltage Various safety functions GPIB control (optional function) External analog control
