World Highest Level Ripple 1 mVp-p with Ultra-Low Noise Level
ASX series, an advanced high voltage power supply, features the world highest level of noise reduction and high stability. With the ultra-low noise of ripple 1 mVp-p as well as high stability of 50 ppm/H at ±3.1 kV output, the series is one of the most popular HV power supplies among various research institutes in Japan and all over the world.
In addition, the ASX series offers the digital setting system having a large-sized five-digit meter and three rotary encoder switches, so you can perform the quick and accurate setting at full scale output voltage of 170 ppm.
ASX series is especially suited for driving photomultiplier tubes used in low-light-level measurement which could be adversely affected by very small noise and aging.
