Wanptek DPS305U 30V 5A Adjustable Switch DC Power Supply 4 Digits 110V Three-Window Four-bit High-Precision Switching DC Regulated Power Supply for Lab Equipment - CNCEST, GX102704

• 1.DPS series products are a three-window four-bit high-precision switching DC regulated power supply , which can display voltage , current and power at the same time . 2.Products are widely used in mobile phone maintenance , computer maintenance , school and production line use , its output voltage and output current can be continuously adjusted between 0 and nominal value . 3.Power supply stability and ripple coefficient are very good, with USB fast charging function and perfect short circuit protection circuit . 4.It is small in size , beautiful in design , convenient in operation , and can work long hours at full load It is loved by the vast number of users. There are two modes of power output : constant voltage output (C V) and constant current output (C C) . 5.The output mode is determined by the voltage and current values set by the user and the load that the user receives . The output voltage or current value of the power supply will not exceed the voltage and current value set by the user. In the constant voltage mode , the output voltage is equal to the voltage set by the user. In constant current mode, the output current value is equal to the current value set by the user.
