1. 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

4. 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
5. Function description.
Open or close the output.
You can press ON/OFF button to open or close the output on any interface.
Lock the button to avoid wrong operation.
On the any interface, you can keep pressing coding potentiometer more than 2s, all buttons are locked. You can see the key lock icon on the right of screen. If you want to unlock all buttons, keep pressing coding potentiometer more than 2s, all buttons are unlocked. The key unlock icon will be displayed on the right of screen.
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
NOTE before using:
1, Output must be used isolated, not in series or on parallel, otherwise it will be burnt.
2, if you connect inductive load (such as motor), the max working current is 1/3 of range. don't over it.
3, 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.
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 chips.
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, When the current is more than 10A or the temperature is more than 45℃ , the fan will begin to work. when the temperature is more than 65°c, the module will stop working
7, 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 47uf, C is over 2200 uf.
