PRODUCT INTRODUCTION
Product Overview
72-8795 Programmable Power Supply is controlled by a Micro Processor
Unit (MPU) that is designed for a communication interface by RS-232 or USB to
computer to enable advanced testing and power delivery by programmable control.
T h e v o l t a g e a n d c u r r e n t a r e c o n t r o l l e d by a 12 b i t D / A C o n v e r t e r
