Product Description
Powerful laboratory power supply up to 320 W
The bench power supply S-LS-81 is specially designed to provide direct current to external devices, with individually-adjustable current and voltage. The power supply unit from the measuring equipment collection is designed for professional and industrial use in labs, the telecommunications sector, workshops with electronic devices, as well as in production facilities and testing institutes. The linear technology used means the device produces a low ripple and low noise.
Individual and precise DC power supply
Thanks to the large LED displays, you can easily read the set output voltage and current values at any time. The numbers are easy to read even in low-light conditions. In addition, the individual displays are marked with their corresponding unit abbreviation, clearly distinguishing between current voltage and amperage.
The easy-to-use dual power supply can be simply and conveniently controlled using the knobs. The knobs allow you to make both rough and fine adjustments to the desired current values from 0 to 64 V DC and 0 to 5 A. During adjustment, you can monitor the values in question on the large LED display and easily modify them to meet your needs. If the power supply unit operates as a constant voltage source (CV), the unit automatically switches to constant current mode (CA) as soon as the set load limit is reached. This prevents damage to the connected devices.
This benchtop power supply unit meets the highest standards of safety: The device is equipped with overload protection (OPP) as well as special overheat protection (OTP) which automatically activates an integrated fan as soon as the maximum temperature is exceeded. These safety measures guarantee safe operation even with intensive and ongoing use.
Non-slip rubber feet ensure additional stability for the device while also protecting the work surface from unwanted scratches. The power supply is also equipped with a handle and can also be used as a mobile unit thanks to its light weight. The bench power supply unit from Stamos Soldering is a thoroughly professional device for individually supplying direct current to various external devices and equipment.

Does what it says on the tin
Cheaply built, but it is cheap. Works nicely, no complaints everything works as described. Decent shipping speed. Smalle fan kicks on when working hard, kicks off quickly too. Accurate.

Does what it's supposed to do
The lab transformer can be set very precisely and is an asset for jobs that require testing equipment. Value for the money. Only instructions were missing, but they were quickly found on the internet.

Power supply Model: S-LS-81
It's a very nice power supply for the price! The delivery time was also very satisfactory. So all in all I am very satisfied.

precise power supply simply lacks a switch allowing not to cut everything to make certain connections that said it returns to its last setting -

measuring lines
Given the price, I didn't expect such high quality. The voltage and current limitation can be perfectly adjusted using the coarse and fine settings and their values remain constant over days. The residual ripple is very low. Two devices can be connected perfectly in series. If the extremely shabby measuring lines hadn't been there, I would have given full marks. I would buy the devices again and again.

High voltage of 64V, correct current of 5A, Ventilation under thermostat makes use silent in 80% of cases. A synoptic view of this power supply would allow us to verify that it is indeed linear, because its weight dissuades us from doing so.
