【Philippines spot】Nice Power Adjustable 30V 20A Switching DC Power Supply 4 Digits LCD Plating Power Supply 30v 30a For Battery Chargign Computer Mobile Phone Repair

PRODUCT BRIEFThe R-SPS series of adjustable regulated DC power supply designed for use in laboratories, schools and production lines.Both output voltage and output current are continuously adjustable between 0 and nominal.The stability and ripple factor of the power supply are very good and have a perfect protection circuit. Can work at full load for along time. This power supply can be used as both a regulated power supply and a regulated current supply.WORK REQUIEMENT1. AC input: Please make sure the input voltage of this product230V±10% 50Hz2. Do not use in an environment where the ambient temperatureexceeds 40 degrees Celsius. The cooling fan is located at the rear of the device and should have enough space for cooling.Warning:Incorrect AC voltage input will cause serious damage to the device.Please make sure the required input voltage value.OPERATION INSTRUCTIONThere are two types of power output modes: constant voltage output (CV) and constant current output (CC). The output modeis determined by the voltage and current values set by the user and the load connected by the user. The output voltage or current value of the power supply won't exceed the voltage and current values set by the user. In constant voltage mode, the output voltage value is equal to the user-set voltage value. In constant current mode, the output current value is equal to the user-set current value.For example: the voltage value is set to 5V and the current value is set to 5A.Steps1. Turn on the powe switch2. Adjust the voltage adjustment knob to 5V3. Connect the“positive”and“negative”with wires and adjust the current knob to 5A.4. Disconnect the wire and connect the load to use.CONNECTTHE LOAD1. Rotate the terminal knob by turning it counterclockwise2. Insert the load terminal3. Turn the terminal knob clockwise4. Banana plug can be directly inserted into the terminal holeCONSTANT VOLTAGE /CONSTANT CURRENT CHARACTERISTICSThe working characteristics of this series of power supplies are constant voltage/constant current automatic conversion type,which can automatically change between constant voltage and constant current states with load changes. The intersection between constant voltage and constant current mode is called conversion point.For example, if the load causes the power supply to operate in a constant voltage mode, a constant voltage is output. As the load increases, the output voltage will remain constant and the output current will increase. When the current value reaches the set current limit value, the power supply will automatically switch to constant current mode. The output current remains stable and the output voltage decreases proportionally as the load increases further. The conversion of constant voltage and constant current is indicated by the LED on the front panel.CV indicator light is on during constant voltage, CC indicator is on when constant current.FUSE REPLACEMENTIf the fuse blows,the power supply will stop working.To find and correct the cause of the blown fuse,then replace it with a fuse of the same specification.PRODUCT MAINTANCE1.
