Laboratory power supply with memory function 0-30VDC 0-5A USB / RS232 + CD S-LS-31

Manufacturer number: Stamos Soldering 10021061

Stamos Soldering 's professional laboratory power supply is designed to convert alternating current into direct current of a selected voltage. This gives the ability to provide electrical power to various devices used for scientific purposes, industry or telecommunications industry. The usefulness of the equipment is due to the channel with a voltage of up to 30 V, an output current of up to 5 A, and with plus and minus ports.

For added convenience, the device is equipped with an RS232 port and comes with a USB cable. With their help, the power supply can be connected to a computer, making it easier to control and program the equipment. The necessary software has been saved on the CD included in the package.

Control over the operation of the power supply is provided by 2 easy-to-read LED displays. They show four-digit values relating to voltage and current and their units. In addition, the LEDs indicate panel lock, active protection system and memory mode activated. A convenient dial and buttons are used for control. With it you can precisely set the correct values, determine the mode of operation.

The built-in memory function will greatly facilitate the work on the power supply. It is used to save and restore previous settings. With the help of this mode, the power supply will remember the initial and exact parameters, the inclusion/exclusion of the sound signal, the level of voltage and current, as well as whether the outputs are to be switched on/off.

The user's safety is taken care of by a special system that will shut down the power supply when it reaches too high a temperature. In addition, there is an overload protection system and a panel lock that prevents accidental change of settings. In addition, the equipment is quiet, which significantly affects the comfort of work.Rubber feet protect the equipment from slipping on the work surface.
