Manufacturer number: Stamos Soldering 10021058. The Stamos Soldering professional laboratory power supply is designed to convert alternating current to direct current at a selected voltage. This allows it to supply power to a variety of devices used in research, industry, and telecommunications. Its versatility is demonstrated by three channels, each with a positive and negative output. If necessary, all of them can operate simultaneously. The first two channels have three operating modes: - independent - the channels operate independently of each other at a voltage of 30 V and a current of 5 A; - parallel - the current increases to 10 A; - series - the current reaches 60 V at a current of 5 A. Four easy-to-read LED displays provide control over the power supply. They show four-digit values for voltage and current, along with their units. Additionally, LEDs indicate the currently selected function. Controls are provided by convenient knobs and buttons. These allow for precise setting of the desired values and selection of the operating mode and channel. User safety is ensured by a special system that shuts down the power supply when it reaches excessive temperatures. Furthermore, the device is quiet, significantly improving work comfort. A built-in handle makes transporting the device easy, and rubber feet prevent slipping on the work surface. Product features: - Versatility - three channels and three operating modes, - Precise adjustment - knobs and buttons for smooth parameter setting, - Easy to read - four large LCD screens, - Safety - overheating protection system, - Mobility - compact size and a handle for easy transport.
