Product Description
Powerful laboratory power supply with up to 300 W and three channels
The bench power supply S-LS-74 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 dials allow you to precisely adjust the values and thereby guarantee exact setting of the desired current from 0 to 30 V DC and 0 to 5 A for channels I and II, and 0 to 5 V and 0 to 3 A for channel III. During adjustment, you can observe the values in question on the four LED displays and easily modify them to meet your needs. Each of the three channels can be adjusted separately and each supplies one of the three current outputs with the set current values.
You can easily choose between two different modes with this dual lab power supply: Parallel or series mode. In series mode you can work with twice the voltage of 60 V, while parallel mode allows you to operate with only one channel at double the current of 10 A. The power supply unit's output can thus be adapted to your individual requirements.
This benchtop power supply unit meets the highest standards of safety: The device is equipped with 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 made to be portable thanks to its light weight and can also be used as a mobile unit. The bench power supply unit from Stamos Soldering is a thoroughly professional device for individually supplying direct current to various external devices and equipment.

some small faults such as the positioning of the earths between the plus and minus outputs "standard spacing" the operation of the fan constantly while the outputs are not active, this can be annoying if there are other devices. it was not complicated to add a CTN with a small regulation. tested at no load max voltage: 32.01V master 31.98V slave and 5.03V with my Uni-T UT61E multimeter. and Fluke 77 recently recalibrated, value varying to 0.01V. when the power supply is turned off after 1 minute, we measure 0.005V, still empty. On the power supply, the output voltmeters are precise. Otherwise good value for money. Power supply not tested, still in power. see the manufacturer's technical characteristics.

Greetings I bought this product and after unpacking it I found that the product was defective. the back side is pressed together with the cooling fan. so the device does not work. I reported it to the company but I did not receive any answer or solution to this problem. I bought a faulty product. I have no further intention of buying from this distributor. So anyone should buy here.

Hello everyone. I bought this product, which arrived as expected in about 5 days. After unpacking, I saw that the parts were damaged. The fan is dented in the back with the mounting. it affects the operation because it cannot properly cool the electrical inside of the device, so I received a faulty product. I reported it to the seller, but there was no response from them. I would like to buy more from them, but after that I give up on my intention to buy. So, no warranty, no semi. I bought a defective product and there is no way to solve it on the part of the company. So if anyone decides to buy, there is no response in the event of a problem and for solution.
