Product Description

Bench power supply - 0-30 V, 0-5 A DC, 250 W - 4 memory spaces

The bench power supply S-LS-30 is specially designed to provide direct current to external devices, with individually-adjustable current and voltage. The power supply unit is very quiet and is designed for professional and industrial use in labs, the telecommunication sector, workshops with electronic devices and production facilities. The linear technology used means the device produces only a low ripple. The device also has a high adjustment and display resolution of 10 mV / 1 mA. Whether you're a professional in weather and environmental research or working on electrical projects around the house, the laboratory equipment from Stamos Soldering enriches your work.

Thanks to the two large and colourful LED displays, you can easily read the set voltage and current at any time. The values are shown to the fourth digit on the LED screens, so that even the most accurate values can be represented. The numbers are easy to read even in low-light conditions. In addition, the values are shown with their corresponding unit acronyms, clearly distinguishing between current voltage and amperage.

With this additional fine-tuning, the dual laboratory power supply can be operated in a more individual and more precise manner to provide the exact amount of power that you need. The voltage or current can be fine-tuned to 10 mV / 1 mA. The lab power supply unit also has four memory spaces.

With the laboratory power supply you get an apparatus with a high safety standard: The device is equipped with overvoltage protection (OVP), overcurrent protection (OCP) and a special overheating protection (OTP), which automatically activates an integrated fan as soon as the maximum temperature is exceeded. This safety system guarantees safe operation of the power supply, even with intensive and long-term use. Furthermore, the power supply has a control panel lock to prevent accidental changing of the set parameters.

The desired amperage can also be set individually on this laboratory power supply using special rotary controls. The rotary controls allow both a coarse and a fine adjustment of the values and thus guarantee an exact setting option for the desired current intensity. During the setting you can observe the respective values on the large LED displays and easily adapt them to your needs.

The dual power supply is made of sturdy sheet steel which guarantees high resilience and a long service life. The device emits a beeping sound when it is turned on or off which can likewise be turned on or off. 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.

Laboratory power supply - 0-30 V

It is characterized by an excellent price-value-technical parameter ratio. It is easy to use and has a clear user interface. Accuracy for its category. Attractive appearance. The negative is that they didn't design a handle for it.

Great power supply at a reasonable price

I've been looking for a power supply with a good price-performance ratio and good reviews for a long time. I found it! I come from the HW development area and am totally satisfied with the features at this price.

It's going ok

The fan is regulated and the device produces a moderate background noise under load. Unfortunately, this fan runs constantly audibly even without load, which is annoying in quiet environments. can. Otherwise an easy-to-use device.

Dear customer, we are pleased when reviews are submitted about the devices we offer. The advantages of the function are certainly always highlighted on our part. Unfortunately, not all comfort needs can be taken into account due to the design and application. Thank you for your understanding. Kind regards, your expondo team
