Adjustable DC Lab Power Supply Variable Bench Switching 0-30/60/120V

WPS series programmable DC stabilized power supplyProduct DescriptionWPS series products are three-window, four-digit digital display high-precision program-controlled DC voltage stabilized power supply, which can display voltage, current and power at the same time. The products are widely used in cell phone repair, computer repair, battery charging, school teaching and production line use. The output voltage and output current can be continuously adjusted between 0 and nominal value by using coding potentiometer, and the set value can be displayed in advance, which is convenient to use and adjust. This machine has USB fast charging function and supports many kinds of fast charging protocols. With perfect OVP, OCP short circuit protection circuit, the product also provides the upper computer communication function (optional), which is convenient for users to connect the power supply with PC by using USB or RS485 connecting cable, and it can also realize USB to RS232/485 interface by using different converting cables, so that the power supply can be controlled and used by software interface to realize remote operation. The stability and ripple factor of the power supply are very good. Its small size, beautiful design, easy to operate, full load can work for a long time, loved by users.
