Longwei Electric 3005-2KD Manual

Thank you for purchasing and using Longwei power series products, in order to make
you better use this product, please read the manual carefully before use, and keep it
properly for future reference!
1. Brief introduction
This series of DC regulated power supply is a switching type regulated power supply,
which has the advantages of high precision, high efficiency, low weight, energy saving and
environmental protection. Perfect protection function, with overvoltage,
overtemperature, overload, current limit and other multiple protection functions, can
effectively protect your product and power supply itself from damage. Output voltage
regulation, steady current automatic conversion, can be used as a regulated power supply,
can also be used as a stable current power supply.
The power supply has two outputs, which are changed by their respective voltage
and current knobs. The power supply additionally provides two fixed 5V/2A output ports
for user convenience.
The power supply can be connected in series or parallel to change the two outputs:
to a series output to increase the voltage range, or parallel outputs to increase the
current range.
The power display window can display the output voltage, current and power. When
the output is independent, the voltage, current and power of the two outputs are
displayed in their respective windows. When series or parallel output is selected, the total
voltage, total current and total power are displayed in the first window, and the second
window is not displayed.
