Very good power supply

A very nice power supply for its price. The product is easy to use and its quality is good. Also the USB control works very well. The fan noise is low so you can also use it in a quiet room (which I actually was a bit worried about).

Product Description

Bench Power Supply - 0-30 V, 0-5 A DC, 250 W - USB - 4 memory spaces

The bench power supply S-LS-31 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. The benchtop dual power supply is also equipped with an RS232 and USB port for remote operation and data collection via PC. 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 easy-to-use dual power supply can be simply and conveniently controlled using the digital buttons. The device also has four memory function buttons for retrieving settings.

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. The laboratory power supply unit also has a control panel lock to prevent the set parameters from being accidentally changed.

This power supply has special knobs that allow you to make both rough and fine 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. 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.

Fully satisfied

Perfect power supply for my uses, the price paid corresponds to the quality of the components. The regulation of voltage and current is very precise, easy and quick. The memories and the on/off button are very convenient and effective.
