Laboratory Power Supply - 0-30 V - 0-3 A DC - 90 W

The laboratory power supply S-LS-33 is specially designed to provide direct current to external devices, with individually-adjustable current and voltage. The power supply is very quiet and is perfect for use in schools or for hobbies. The linear technology used means the device produces only a low ripple and low noise. The device also has a high adjustment and display resolution of 100 mV / 10 mA. Whether you're a professional in development or working on electrical projects around the house, the laboratory equipment from Stamos Soldering enriches your work.

Individual and precise power supply


Thanks to the large LED display, you can easily read the set voltage and amperage values at any time. The values are shown to the fourth digit on the LED display, 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 100 mV / 10 mA. The easy-to-use dual power supply can be simply and conveniently controlled using the knobs.


This double power supply unit meets the highest standards of safety: The device is equipped with overvoltage protection (OVP), overcurrent protection (OCP) as well as special overheat protection (OTP) which automatically activates an integrated fan as soon as the maximum temperature is exceeded. With this safety system, safe operation is guaranteed, even with intensive and ongoing use.


This power supply has special knobs that allow you to individually adjust the desired current. The knobs allow you to make both rough and fine adjustments to the desired current values from 0 to 30 V DC and 0 to 3 A. During adjustment, you can observe the values in question on the large LED display and easily modify them to meet your needs.


The power supply also has a built-in overheat protection which starts the cooling fan as soon as the device temperature rises above 40 °C. The fan ceases to run once the device reaches 35 °C.


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.
