Product Description
Bench Power Supply - 0-30 V, 0-5 A DC, 150 W - USB
The bench power supply S-LS-29 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 benchtop dual power supply is also equipped with an RS232 and USB port for remote operation and data collection. 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.
The three different modes allow you to easily adjust the voltage from 0 to 30 V 0÷5A. Modes one and two are for manual data entry. In the third mode, you can adjust the parameters via PC using a special software program. This software is compatible with Windows XP, Vista, 7, 8 and 10.
Thanks to the two large 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 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 lab power supply also has four LED diodes which, among other things, indicate which voltage is turned on or whether the overheat protection is active.
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.
This double power supply unit meets the highest standards of safety: The device is equipped with 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. 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.

An indispensable tool for the laboratory, made with care and features uncommon in models from other brands. Tested to the limits of its performance, as per the reference technical data sheet, it was able to respond effectively even for fairly long periods of time. The only flaw, albeit a minor one, is the cooling fan which does not seem to be thermostated and, therefore, is forced to operate at constant speed. In my opinion, the price-quality compromise is good also because the circuit has been equipped with an excellent power transformer which guarantees professional level performance. Excellent delivery times and the online service provided by Amazon.
