• ADSP-HV80 power supply is a high-precision, high-stability, low-temperature drift, multi-channel high-voltage output, and a high-voltage power supply with filament heating driver specially designed for the drive of HITACHI CD-SEM scanning electron microscope electron gun.
• The ADSP-HV80 power supply has the same power input interface, LINK interface, serial communication interface and communication protocol, high-voltage output interface, high-voltage cable and high-voltage plug as the original HVPS. It can be directly used to replace all models of HITACHI’s original CD-SEM dedicated HVPS without any modification.
• We use a new design concept and adopt a new generation of high-precision, compact modular high-voltage unit, which makes the ADSP-HV80 high-voltage power supply reduced by a quarter of the volume and half of the weight compared to Hitachi's original HVPS. The power consumption and heat generation of this unit have been drastically reduced by about 40%.
• More importantly, we designed the new HVPS with a wider high-voltage output range, and built-in a variety of HITACHI original HVPS models of V1/V2 characteristic curve library, the user only needs to set one parameter to change The high-voltage output value range and characteristics of the HVPS, then it can be applied to all different types of HITACHI CD-SEM machines, such as S-8820, S-8840, S-9200, S-9220, S-9260, S-9300, S- 9380 and other models.
