1The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one. 2This module has power-down stored function and can store 10 groups preset value. 3Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. 4LCD display on the module has the function digital voltmeter and ammeter. 5On the setting data interface, you can adjust over-voltage value, over-current value, over-power value, data set and LCD brightness Note:1.This is DPS3005 /DPS5005 communication version, there is a communication interface on the back.2.USB + Bluetooth means: DPS3005/DPS5005+ USB communication board+ Bluetooth communication BoardA: We have the file for upper computer installation and software, you can contact us.B: Upper computer installation, connection by USB and Bluetooth video:you can go to RD tech youtube channel to check3.DPS3005 /DPS5005 have same functions, only the technical parameters are different,for example, voltage, current ,etc.Very important: 1.Before buying this product, please download the upper computer software and test, if it fits your computer , you can buy2.the upper computer only support ForWin7 and aboveFeatures:The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one.This module has power-down stored function and can store 10 groups preset value. And it also has the function of extracting quickly two groups stored value.Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required.LCD display on the module has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc.On the output state remind area, you can see that output opens or not, the state of constant voltage and constant current, output is normal or not, the key is locked or not, and the current data groups that is being used.On the setting data interface, you can adjust over-voltage value, over-current value, over-power value, data set and LCD brightness.This module has many advantages, small size, advanced function, good visual effect, high operability, high-precision, being used independently, being inset into the device and been widely applied.Specification:Model(Optional)DPS3005DPS5005Inputvoltage6.00-40.00V6.00-55.00VOutputvoltage0V-32.00V0V-50.00VOutputcurrent0-5.000A0-5.000AOutputpower0-160.0W0-250.0WVoltageresolution0.01V0.01VCurrentresolution0.001A0.001ASize80*44*45mm/3.1*1.7*1.8inWeightApprox.138g/4.9ozConnection descriptionIN+: Input positive, IN-: Input negative:OUT+: Output positive, OUT-: Output negativeNote: Input voltage range is DC 6-40V and 40v is the limit voltage; please leave a room to use. Or else it will be burnt. The input must be DC power supply, not AC 220V, or else it will be burnt too. Though this module has reverse connection protection and output short circuit protection, you can muse be in strict accordance with connection description to connect. If you connect the supply power with output, the module will be burnt.Operating instructionsWhen connect the power supply, the screen shows welcome window firstly and then comes into main interface.
