Comprehensive test and measurement service provider-Shenzhen Weike Electronic Technology Co.
The TH6220 series are single-channel programmable linear DC power supplies. This series of instruments have superior performance, clear display, easy operation and compact size, which are very suitable for the application needs of college laboratories and bench test and maintenance. At the same time, this series of instruments provide RS232 interface and USB interface, support for serial commands, for computer remote operation provides the conditions.
Functional Features
A. Linear programmable output design
The biggest advantage of linear power supply is high precision, high stability, low ripple, low noise, applicable to the need for stability and small ripple occasions such as test benches, integrated systems, etc.; also applies to aging and other occasions that require a long period of time.
B. Compact size
The TH6220 series of linear programmable power supplies is a vertical design with a height of 162mm, a width of 111mm, and a depth of 243/275mm, which occupies a small footprint and is ideal for bench use.
C. Simple and fast operation
TH6220 series linear programmable power supply panel settings are reasonable and clear, voltage/current fast switching buttons with cursor movement keys, adjustment and confirmation knobs, you can quickly set the required voltage and current values.
5 groups of different voltage and current values can be saved and recalled by quick operation directly on the panel. Current settings are automatically saved when power down and recalled next time power on.
Voltage and current can be set upper and lower limits to realize automatic judgment.
The key lock switch button enables the keyboard lock function to prevent misuse.
The output switch button can activate the output or cut off the output with one key to ensure the output is safe and controllable.
D. Two interfaces, support SCPI instruction set
TH6220 series linear programmable power supplies come standard with RS232C and USB DEVICE interfaces. Supporting SCPI instruction set, users can program their own control.
