Chapter2 Quick Start 
This chapter introduces the front panel, the rear panel, key functions and VFD 
display function of the power supply, make sure that you can quickly know the 
appearance, instruction and the key function before you operate the power 
supply. Help you make better use of this series of power supply. 
2.1 Brief Introduction 
IT6900 series power supplies are high performance single-output 
programmable DC power supplied with communication interface. This series of 
programmable DC power supply can output the maximum voltage or current 
with a fixed power for customers. Take IT6922A (60V/5A/100W) for example, 
when you select 60V for the output voltage, the output power of IT6922A is 
100W, so in this case the maximum output current is 100W/60V = 1.66A. When 
you select 20V for the output voltage, the maximum output current 100W/20V = 
5A, but when the output voltage is down to 10V, due to IT6922A maximum 
current is 5A, so in this case the maximum output current is 5A. IT6900 series 
power comes with a standard communication interface RS232/USB/RS485, 
both desktop and system-based features, can be designed and tested 
according to your needs and provide multi-purpose solutions.
