Chapter 1 Overview
Thank you for purchasing and using our products, before you use this instrument,
please first confirm the matters according to the manual chapter 7 "set and warranty", if
there is any discrepancy, please contact us as soon as possible in order to protect your rights
and interests.
1.1 Introduction
TH6700A series is a programmable switching DC power supply. This series of
instrument is powerful, superior performance, and the use of digital tube display, display
clear, quick and easy to operate, can be well adapted to the production site rapid operation
needs and laboratory needs of high precision and high stability, at the same time, the
instrument provides a USB interface and LAN port for the instrument to be used in the
remote operation of the computer to provide the conditions.
The special features and advantages of the instrument are listed below:
Adopt digital tube display, reduce power consumption, display simple and clear
High accuracy and resolution
Low ripple and low noise
Intelligent fan control saves energy and reduces noise
Software control and detection via computer
Precise fine-tuning of values by knob and cursor
High current power and high stability
1.2 Conditions of use

1.5 Notes
Please do not use in dusty, vibration, direct sunlight, corrosive gases and other adverse
environments.
If the instrument is not used for a long time, please store it in the original packing box
or similar box in a ventilated room with the temperature of 5℃～40℃and relative
humidity not more than 85%RH. The air should not contain harmful impurities that corrode
the measuring instrument, and it should be avoided from direct sunlight.
This instrument has been carefully designed to minimize spurious interference due to
inputs from the AC power supply side, however, it should still be used in as low a spurious
environment as possible, and if this cannot be avoided, a power supply filter should be
installed.
There is a cooling fan at the back of the instrument and cooling vents on the left and
right to avoid the internal temperature from rising and affecting the accuracy, please make
sure the instrument is in a well ventilated condition.
Do not switch the instrument on and off frequently as this may cause loss of stored
data.
