PRODUCT QUESTIONS：
1.Q: What is the differences between DPS5020, DPS5020-USB and DPS5020-USB-BT?
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.
2. Q:Can I buy several devices and use them in series or in parallel to get higher output voltage or current?
A: Our products can only be used alone, their output must be used isolated, not in series or on parallel, otherwise the device will be burnt.
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.
4. Q:What is the correct way to use this device?
A: Before using, please connect all wire well first, then turn on the input power supply, not turn on the input power supply first, then connect the wire. Otherwise it will cause the fuse and MOS damaged.
5. Q:what should I notice when I get it?
A: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 chips.
6. Q: can I use AC to DC converter or transformer to power on it?
A:if you use AC-DC converter or transformer coil, please add rectifier (rectifier bridge) and filter (more than 4700uf filter capacitor). If input power supply is unstable, please add LC, L is over 47uH, C is over 2200 uf.
7. Q: how does the fan on the power board work?
A: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

| 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.

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.
