1. PRODUCT INTRODUCTION 
1-1. Description 
PSM-series Programmable Power Supply is controlled by Micro Processor 
Unit (MPU) with extreme high accuracy of 200W maximum, and the single 
output with double range (switching between the main panel and 
communication interface) that can easily connect communication interface 
RS-232 or GPIB to computer in order to satisfy users’ demand for auto-testing 
and auto-control. The software commands are fully complied with the SCPI 
format, it’s convenient for user to proceed auto-tested and auto-controlled 
application program. 
The voltage and current are completely controlled by 16 bits D/A 
Converter with higher resolution and accuracy. Also, the digitalization of 
system makes a speedy, precise and convenient input of information controlled 
by keyboard. 
The adjustment of voltage/current is made by software calibration without 
manual error that will increase the preciseness of the instrument. 
The function of Over Voltage Protection (OVP) and Over Current 
Protection (OCP) is set with software and detected with hardware to achieve 
protected function precisely and speedily in order to secure users from danger 
by using the instrument.
