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

PRODUCT QUESTIONS：

A:There are 3 version, No communication version(DPS5020), communication + USB version(DPS5020-USB), communication + USB+ BT (DPS5020-USB-BT).you can only select the Bluetooth connection or USB connection, because the Bluetooth board and USB communication board can only be used alone,For no communication version, there is no commnunication program and hardware to support, not any communication function, can't be updated.

3. Q: Can I use it to power on inductive load?

A: If you connect inductive load (such as motor), the max working current is 1/3 of range. don't exceed it.

5. Q:what should I notice when I get it?

Difference between DP,DPS and DPH	1.DPS series are updated version. Panel is different. In DPS series, we change the M1/↑and M2/↓ into V/↑and A/↓. You can press those buttonsto set the voltage and current fast. We add a new function “set default boot open or close output”,Others are not changed. 2.All those power supply can charge the battery directly, don't need external diode. When charging battery, don’t connect battery polarityreversely , otherwise, power parts will bunt. Find the difference between DPS and DP see this video https://www.youtube.com/watch?v=ptt931rrXo8 3.DP power supply and DPS power supply are all buck (step-down) converter. But DPH3205 and DPH5005arebuck-boost (step-down and step-up) converter . 4. DPS3005, DPS5005 DPS5015, DPS5020, DPH5005 and DPS8005 have communication version. You can connect PC and use upper computer

General Information

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

On the main interface, you can press SET key shortly to enter into data setting interface. On the data setting interface, press shortly V/↑or A/↓ to page up or page down to U-SET or I-SET, and then set the output voltage and output current by same way used in the main interface .

Set the protection value.

Page up or page down to S-OVP, S-OCP or S-OPP place to set over-voltage value , over-current value and over-power value correspondingly; when the value is up to the setting value, output will be closed. And then press shortly the coding potentiometer to enter into the status of adjusting the numerical value you want to adjust. Turn coding potentiometer to adjust the numerical value. If you want to exit adjusting the numerical value, press shortly SET key.

Adjust the brightness of screen.

Page up or page down to B-LED, and then press shortly the coding potentiometer to enter into the status of adjusting the brightness of screen. Turn coding potentiometer to adjust the numerical value you need. If you want to exit adjusting the numerical value, press shortly SET key. There are six brightness levels of LCD screen, 0-5 level. Rank 0 is the darkest; rank 5 is the brightest. You can choose what you like.

Data setting and store the specified data group.

Page up or page down to M-PRE, and then press shortly the coding potentiometer to enter into the status of choosing the data groups. Turn coding potentiometer to choose the data group you need to view. Then the data group you need will be displayed. And then press the coding potentiometer to enter into status of changing output state. Turn coding potentiometer to choose ON or OFF. When choose ON, the data group is extracted and the output status remain the same. When choose OFF, the data group is extracted and the output is closed. If you want to exit choosing data set, press shortly SET key. Then press shortly V/↑or A/↓ to page up or page down to other place to adjust the data you need. After data setting done, keep pressing SET key more than 2s, all the data you set are automatically stored into the specified data group. In the same time, you can see the group number on the right of screen. At last you can press shortly SET key back to the main interface.

Set default boot open or close output

Page up or page down to S-INI, and then press shortly the coding potentiometer to enter into the setting status. Set ON, default boot open; set off, default boot close.

Function description.

Open or close the output.

You can press ON/OFF key to open or close the output on any interface.

M0-M9 ten groups data group

M0 group is the boot default data group. When you extract the data group you need, this data group will cover M0 data group and be automatically stored on M0 data group.

Extract Shortcut storage data group M1 or M2.

On the main interface, keep pressing V/↑or A/↓ more than 2s, you can extract Shortcut storage data group M1 or M2 quickly. In the same time the corresponding data group number will displayed on the right of the screen.

Extract the specified data group.

On the main interface, keep pressing SET key more than 2s, the sequence number of data group will be displayed on the right of the screen, you can turn coding potentiometer to choose data group you need. And then press shortly SET key, you can extract the specified data group you need.
