This module has power-down stored function and can store 10 groups' preset values. It also has the function of extracting quickly two groups of 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.
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 0-15.00A, step by 0.01A.
You can view the preset voltage, input voltage, output voltage, preset current, output current, output power, etc. on the output state reminder area, you can see whether the output opens or not, the state of constant voltage and constant current, the output is normal or not, the key is locked or not, and the current data groups that are being used. On the setting data interface, you can adjust the over-voltage value, over-current value, over-power value, data set, and LCD brightness. This module has many advantages, small size, advanced function, good visual effect, high durability, high precision, being used independently, being inset into the device, and being widely applied.

NOTE before using :
- Output must be used isolated, not in series or in parallel, otherwise it will be burnt.
- If you connect an inductive load (such as motor), the max working current is 1/3 of the range. don't over it.
- Before using, please connect all wires well first, then turn on the input power supply, not turn on the input power supply first, and then connect the wire. Otherwise, it will cause the fuse and MOS damaged.
- 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.
- You must make sure that the input voltage is 1.1 times higher than the output voltage. Under large current circumstances, pay attention to heat elimination.
- 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
- If you use an AC-DC converter or transformer coil, please add a rectifier (rectifier bridge) and filter (more than 4700uf filter capacitor). If the input power supply is unstable, please add LC, L is over 47uf, and C is over 2200 uf.
