Product Description: LongWei PDS-3010G 0-30V 0-10A Laboratory Power Supply with USB Port
The PDS-3010G laboratory switching power supply from LongWei is a precise, small-sized device. Equipped with clear four-digit LED displays , it allows convenient monitoring of the setting value, current voltage, output current and output power. The device offers CV (Constant Voltage) and CC (Constant Current) operating modes, which are intuitively indicated by LED diodes . The green color of the diode indicates the voltage mode, while the red color indicates the current mode. Smooth transition between modes is achieved by adjusting the current or voltage limit settings. The use of the PDS-3010G laboratory power supply can be beneficial in various fields, such as electronics , scientific research, or work with electronic systems .

Two operating modes
The PDS-3010G power supply offers independent and precise voltage and current regulation using separate potentiometers. Knobs marked ' V-coarse ' allow for a coarse tension setting, while ' V-fine ' allows for precise adjustments. Similarly, the 'A-coarse ' knobs are for coarse current setting and the ' A-fine ' knobs are for fine adjustment. This method of regulation ensures convenient and accurate setting of output parameters. LED indication provides control and limiting range, indicating whether the power supply is operating in constant voltage (CV) mode with output voltage limiting or in constant current (CC) mode with current limiting. Thanks to these diodes, the user quickly becomes aware of the current operating mode of the device.
