Product model: DPS 5020 General Information

The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one. Its adjustable output voltage range is 0-50.00V, step by 0.01V. Its adjustable output current range is 0-20.00A, step by 0.01A. 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 overvoltage value, overcurrent 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.

Open size: 71mm*39mm Power module size: 93*71*41(mm) (L*W*H)

Length of connecting line: 200mm Fixed hole center distance: 86mm, 64mm

Output voltage resolution: 0.01V Output current resolution: 0.01A

Output Voltage accuracy: ± (0.5% + 1 digit) Output Current accuracy: ± (0.5% + 2 digits)

NOTE: 1. You must make sure that the input voltage is 1.1 times higher than output voltage. U nder large current circumstances, pay attention to heat elimination.

2. Connection between display part and power part should be according to the corresponding words. O therwise it will not work by wrong connection Connection description IN+: Input positive IN-: Input negative:

OUT+: Output positive: OUT-: Output negative

Note: Input voltage range is DC 6-60V and 60v 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 instructions

When connect the power supply, the screen shows welcome window firstly and then comes into main interface. On the main interface, the output set voltage value and the output set current value is on the top of the screen. The big font value on the left are the current real output voltage, the current real output current and the current real output power. Input voltage is on the bottom of the screen. There are some running status icons on the right of the screen, key lock icon, abnormal output status icon, constant voltage and constant current icon, data set tip icon and opening or closing output icon.

Set the output voltage and output current on the main interface.

Press V/↑key shortly, you can enter into voltage setting status. Then press the coding potentiometer, and then enter to adjust the numerical value. Press coding potentiometer to enter into the status of adjusting the numerical value you want to adjust. Turn coding potentiometer to adjust the numerical value. Turn by clockwise rotation to increase the numerical value; Turn by counterclockwise to decrease the numerical value. If you want to exit adjusting the numerical value, press shortly V/↑. In the same time the preset value will be stored. Or you can do nothing in one minute, the status will be automatically existed and the preset will be stored too. You can press A/↓to set the output current by the same way. Set the data on the data setting interface
