Parameter Description

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. Programmable DC power supplyThe above parameters are measured at an ambient temperature of 25±5°C, relative humidity: <80%RH, andpreheated for 30 minutes.The actual parameters will varyslightly.WORK REQUIEMENT1. AC input: Please make sure the input voltage of this product230V±10%50Hz115 V±10%60Hz2.Do not use in an environment where the ambient temperatureexceeds 40 degrees Celsius.The cooling fan is located at therear of the device and should have enough space for cooling.lncorrect AC voltage input will cause serious damageto the device.Please make sure the required inputvoltage value.OPERATION INSTRUCTIONThere are two types of power output modes: constant voltageoutput (CV) and constant current output (CC).The output modeis determined by the voltage and current values set by the userand the load connected by the user.The output voltage or current value of the power supply won't exceed the voltage andcurrent values set by the user. In constant voltage mode, theoutput voltage value is equal to the user-set voltage value.Inconstant current mode, the output current value is equal to theuser-set current value.The 'voltage value is set to 5A1. Turn on the power switchStepsThe voltage value is set to 5A1. Turn on the power switch2. Ajust the voltage adjustment knob to 5VThe current value is set to 5A1. Press Output Button to the OFF state ,then adjust the current to 5A;2. Press Output Button to the ON state,Connect Load to use.CONNECT THE 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 CURRENTCHARACTERISTICsThe working characteristics of this series of power supplies areconstant voltagelconstant current automatic conversion type,which can automatically change between constant voltage andconstant current states with load changes.The intersectionbetween constant voltage and constant current mode is calledconversion point.For example, if the load causes the power supply to operate in a constant voltage mode, a constant voltageis output.As the load increases, the output voltage will remainconstant and the output current will increase. When the currentvalue reaches the set current limit value, the power supply will automatically switch to constant current mode.The outputcurrent remains stable and the output voltage decreases proportionally as the load increases further.The conversion ofconstant voltage and constant current is indicated by the LED onthe front panel.CV indicator light is on during constant voltage, CC indicator ison when constant current.FUSE REPLACEMENTlf the fuse blows, the power supply will stop working.To find andcorrect the cause of the blown fuse, then replace it with a fuse ofthe same specification.PRODUCT MAINTANCE1. Disconnect the power when the product is not in use.2.Unplug the power supply before cleaning.3.Do not use hydrocarbons, chlorides or similar solvents, oruse abrasive cleaners.
