Product Description

Wanptek WPS305B 30V 5A White New Model USB Output 4 Digital Switching Regulated Variable DC Adjustable Power Supply

Product Description

WPS series product is a three-window four-digit display high-precision programmable switching DC regulated power supply, which can display voltage, current, and power at the same time.

Products are widely used in mobile 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 the nominal value using the code potentiometer, and the set value can be pre-displayed, which is convenient for use and adjustment.

This machine has USB fast charging function and supports multiple 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 remotely control the PC computer and other main control equipment through the USB data cable.

The stability and ripple coefficient of the power supply are very good. Its small size, beautiful design, convenient operation, can work for a long time at full load, and are deeply loved by users.
