World Highest Level Ripple 1 mVp-p with Ultra-Low-Noise Level

ASX series, an advanced high voltage power supply, features the world's highest level of noise reduction and high stability. With the ultra-low noise of ripple one mVp-p and high stability of 50 ppm/H at ±3.1 kV output, the series is one of the most popular high voltage 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 that you can perform the quick and accurate setting at a 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 minimal noise and aging.

Options

-LA:

Following functions are to be added.

Door switch

High voltage output cut off by external switch

Remote switch ON/OFF

High voltage output ON/OFF by external relay

Output voltage monitor

0 V to 10 V/maximum output voltage (output impedance 1 kΩ)
same polarity as High Voltage output

-LC: Current limit

Limits output current by dropping output voltage

-LG: GPIB control

For output ON/OFF, output voltage setting (resolution 0.1 V) and switching polarity

-LMh

A load side of the output cable will be MHV plug.

-LRs: RS-232C control

For output ON/OFF, output voltage setting (resolution 0.1 V) and switching polarity

-LSh

A load side of the output cable will be SHV plug.

-LW: Slow start

Takes about 10 seconds to reach a set voltage after turning on the output.
(Takes about 5 seconds if setting half of the output voltage.)

-L(3m), -L(5m), -L(7m): High voltage output shielded cable length change

Please choose high voltage output cable length from 3, 5, 7 meters.

(Please contact nearby sales office if specific length other than above.)

-LRs option and -LG option cannot be selected together. Need to be selected either one.

How to Order

When ordering, add Option No. to Model No. in alphabetical order followed by the cable length.
