Otherwise it will cause the fuse and MOS damaged. 4, when you get the product in the first time, please don't use your hands to touch the components, because human static electricity can damage some chs. 5.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. 6, if you use AC-DC converter or transformer coil, please add rectifier (rectifier bridge) and filter (more than 4700uf filter ). If input power supply is unstable, please add LC, L is over 47uf, C is over 2200 uf. 7.When the current is more than 10A or the temperature is more than 45 °c , the fan will begin to work. when the temperature is more than 65°c, the module will stop working 8. for input power supply , there is a recommended one S-400-36V, it is just recommened, not provide any technical support , please contact that seller ,when you use this for DPS3012, please adjust to lower 40V  output to use , link: https://www.aliexpre.com/item/32882215425.html , please choose 400w/36V

Picture

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 pre those button

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 polarity

rely , 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 bu (step-down) converter.  But DPH3205 and DPH5005 is bu-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 6-40V 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.

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 lo icon, abnormal output status icon, constant voltage and constant current icon, data set t icon and opening or closing output icon.

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

Pre V/↑key shortly, you can enter into voltage setting status. Then pre the coding potentiometer, and then enter to adjust the numerical value. Pre 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 clowise rotation to increase the numerical value; Turn by counterclowise to decrease the numerical value. If you want to exit adjusting the numerical value, pre 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 pre A/↓to set the output current by the same way.

Set the data on the data setting interface

On the main interface, you can pre SET key shortly to enter into data setting interface. On the data setting interface, pre 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 pre 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, pre shortly SET key.

Adjust the brightne of screen.

Page up or page down to B-LED, and then pre shortly the coding potentiometer to enter into the status of adjusting the brightne of screen. Turn coding potentiometer to adjust the numerical value you need. If you want to exit adjusting the numerical value, pre shortly SET key. There are six brightne 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 pre 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 pre 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, pre shortly SET key. Then pre shortly V/↑or A/↓ to page up or page down to other place to adjust the data you need. After data setting done, keep preing 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 pre shortly SET key ba to the main interface.

Set default boot open or close output

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

Function descrtion.

Open or close the output .

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

Lo the button to avoid wrong operation.
