Laboratory power supply LongWei PS3010DF 0-30V 10A

Index: JBW-19289 EAN: 5904422363253
Laboratory power supply with precise voltage and current regulation function. The LongWei PS3010DF is equipped with two potentiometers: Coarse, is used to set the "coarse" output voltage and current, while Fine allows precise adjustment of these values. The power supply enables adjustment of voltage within the range from 0 V to 30 V and current within the range from 0 A to 10 A. The device supports C.V mode (output voltage stabilisation) and C.C mode (output current stabilisation), whose operation is indicated by LEDs. The PSU is equipped with a three-level LED display, which displays current, voltage, current and power parameters. The PS3010DF has a USB type A connector on the front panel.

Question: Good day, I would like to know if this power supply model has short circuit protection?
Answer: The power supply has an output current regulator. The tripping time is fractions of
seconds. It is more of a regulator than a short-circuit protector
- In the case of protections, a curve is defined: tripping time X short-circuit current
short-circuit current. In the case of a power supply - on the output side, the manufacturer does not
defines something like this - when the set current is exceeded
output -> the regulator will cause output voltage limitation.
The response time is a fraction of a second. However, the power supply has at the output
capacitance and a full short circuit at the maximum output voltage of 30V
will cause a short 'discharge' in the form of a spark on the contacts of the switch
causing a short circuit. It is important to keep this in mind. In this sense, it is
Short-circuit protection through an output current regulator
