What's in the box:

220V 0-30V 0-10A DC Power Supply Switching Voltage-stabilized Source Regulated Power Supply Stabilized Voltage Supply CV & CC Dual Output Modes Adjustable Output Voltage Current 4-digit LCD Display 5V/2A USB Output (Black)

This SPS series of regulated DC power supply has good stability and ripple factor. Can work at full load for a long time for its perfect protection circuit. Both output voltage and output current are continuously adjustable between 0 and nominal value. The power supply can be used as both a regulated power supply and a regulated current supply. Very suitable for laboratories, schools and production lines.

Features:
Dual Power Output Modes: including constant voltage output(CV) and constant current output(CC), determined by the voltage and current values set and the load connected by the user.
Adjustable Output Voltage & Current: output voltage and output current can be continuously adjusted between 0 and nominal value.
USB Quick Charging Function: the machine has built-in fast charging protocol identification chip that supports 5V2A USB fast charging function.
Reliable & Safety Operation: it has over voltage protection(OVP), over current protection(OCP), over temperature protection(OTP) and short circuit protection function.
Clear LCD Display: 4 digits digital displays voltage, current and power on the LCD screen intuitively, and features of voltage stabilization, current limiting, high precision and simple operation.
Wide Application: can be used in mobile phone maintenance, computer maintenance, electrical maintenance, school laboratories scientific research and production line use and all other need DC regulated power supply.
