Product Description

Dual Power Supply - 2x 0-30 V, 0-5 A DC, 550 W

The dual power supply S-LS-28 is specially designed to provide direct current to external devices, with individually-adjustable current and voltage. The power supply unit is designed for professional and industrial use in labs, the telecommunication sector, workshops with electronic devices and production facilities. 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.
This dual lab power supply allows you to easily choose between two different modes, parallel or series mode. In series mode, you can work with the double voltage of 60 volts, while parallel mode allows you to operate with only one channel at a doubled current of 10 amps. In this way, you can adjust the power of the power supply unit to suit your individual needs.
The power supply is equipped with three galvanically separated outputs each for positive and negative current, which enable an appropriate distribution of voltage and current to external devices. In addition, all outputs, and therefore multiple devices, can be used at the same time. The double benchtop power supply can thus be used as both a power source and a power sink.
Thanks to the four large LED displays, you can easily read the set voltage and amperage values 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 glowing red 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. The dual power supply also has three LED diodes that indicate which voltage is turned on: 5 V, 3.3 V or 2.5 V.
A separate switch allows you to make further small adjustments to the current voltage for the adjustable channel III. This makes it possible to obtain different voltages of 2.5 V, 3.3 V or 5 V with the same channel selection. 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.
This dual power supply unit meets the highest standards of safety: The device is equipped with special overheat protection 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 make both rough and fine individual adjustments to the desired current values, guaranteeing precision. During adjustment, you can observe the values in question on the large LED displays and easily modify them to meet your needs.
The dual power supply is made of sturdy sheet steel which guarantees high resilience and a long service life. 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 dual power supply unit from Stamos Soldering is a thoroughly professional device for individually supplying direct current to various external tools and equipment.
