Wanptek's new series products. This model is a miniature switching DC power supply. The output voltage and current can be controlled and adjusted by variable resistors respectively, so it provides more convenience and accuracy in the adjustment of voltage and current. The panel also provides high-precision two/three-window digital tube display of voltage, current and power, so that users can intuitively see the current use status and various parameters of the machine1.Small size, light weight and high power density.2.Constant pressure and constant current switch automatically.3.LED display of voltage, current and power, high precision and features of voltage stabilization, current limiting, and simple operation.4.Adjustable Output Voltage & Current: output voltage and output current can be continuously5.adjusted between 0 and nominal value with fine regulating and coarse regulating6.it has over voltage protection(OVP), over current protection(OCP), over temperature protection7.Temperature controlled fan cooling, low noise, long life.8.Dual voltage input and convenient choice.9.Output Voltage ranges from 0 to rating voltage with continuous adjustment .10.Output current ranges from 0 to rating current with continuous adjustment11. AC 110v and 220v can work , rest assured to choose.12.
