Detail
60W6A high-power adjustable Buck-Boost power supply module, long handle to adjust constant voltage and current, with display and housing
(constant voltage constant current LCD version)
Delivery does not include power adapters, which must be purchased separately.It is recommended to use an adapter with a voltage of 15~24V/current of 2~5A.If the output power demand, choose the high power adapter.Insert module DC port second desktop power supply.
Note: the shell is a DIY package, which needs to be assembled by the customer. It is easy to operate.Acrylic shell and liquid crystal screen cover with protective film, please tear the film before assembling, the product will be more transparent.

Output voltage: 0.5-30V
Output current: Output current: the fanless version can work stably in 4A for a long time, and the fan version can reach 6A
Output power: Fanless version 35W, fan version 60W
Voltage display resolution: 0.01V, accuracy error 1%
Current display resolution: 0.001A, accuracy error 1%
Conversion efficiency: about 88%
Soft-start: Yes (very powerful with load startup, startup may fail)
Input reverse protection: Yes
Output anti-intrusion: Yes
Short circuit protection: yes
Temperature protection: 100℃
Power protection: 60W
Over-current protection: 6A
Operating frequency: 180KHZ
Fan rotation conditions: current greater than 3A, or power greater than 20 watts, or temperature greater than 40℃.
Size: fanless version length * width * height 72*59*32mm
fan version length * width * height 72*59*43mm
Mounting hole: diameter 3mm
Weight: fanless version 81g
fan version 107g
3. Function Description:
3.1. Module has IN / OUT, ON / OFF two buttons: IN / OUT button to switch the input voltage and output voltage display, long press to switch the output current output power display; ON / OFF button control output ON or OFF, long press Set power on default output status is ON or OFF.
3.2.CC is the current setting potentiometer, clockwise rotation, can increase the set current, when the load current reaches the set current, enter the constant current state, CC constant current indicator (red) lights up; the right CV is the voltage setting Potentiometer, clockwise rotation, can increase the output voltage. ON indicator is the output status indicator, when the output voltage is on, otherwise off.
4. How to use:
4.1. Used as an ordinary buck-boost module with over-current protection capability
(1) Adjust the CV constant voltage potentiometer so that the output voltage reaches the voltage you want.
(2) Directly connect the output end with a short line (can directly short the output end!).Adjust CC constant current potentiometer so that the output current reaches the predetermined overcurrent protection value.(for example, the current value displayed by the module is 2A, so the maximum current can only reach 2A when you use the module, and the red constant voltage and current indicator is on when the current reaches 2A, otherwise the indicator is off)
Caution: When using in this state, there will be a voltage drop of 0 ~ 0.2V due to the current sampling resistor at the output. At the same time, the input and output leads will have a certain linear voltage drop This is a normal phenomenon!
4.2. Used as a battery charger
Without constant current function of the module can not be used to charge the battery, due to the power of the battery and the charger pressure drop is large, resulting in charging current is too large, causing damage to the battery, so the beginning of the battery to use constant Flow charging, when the charge to a certain extent automatically switch back to constant voltage charging.
(1) Determine the float voltage and charging current for which you need the rechargeable battery (if the lithium battery parameter is 3.7V / 2200mAh then the float voltage is 4.2V and the maximum charging current is 1C, ie 2200mA)
(2) Under no-load condition, the multimeter measures the output voltage and adjusts the constant voltage potentiometer so that the output voltage reaches the float voltage. (If the 3.7V lithium battery is charged, adjust the output voltage to 4.2V)
(3) Measure the output short-circuit current with 10A current meter (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer so that the output current reaches the predetermined charge current value;
(4) Connect the battery, charging.
(Steps 1, 2 and 3 are as follows: input termination power supply, the output is not connected to the battery load)
4.3. Used as LED constant current driver module
(1) Make sure you need to drive the LED operating current and the maximum operating voltage;
(2) Under no-load conditions, the multimeter measures the output voltage and adjusts the constant voltage potentiometer so that the output voltage reaches the maximum operating voltage of the LED.
(3) directly connect the output with a short line (can directly short the output end!)., adjust the constant current potentiometer to make the output current reach the predetermined LED working current;
(4) connected to the LED, test machine.
(Steps 1, 2, and 3 are as follows: Input the power and output the no-load LED.)
Note: This module is more than 3A, 35W use, please strengthen the heat! ! !
5. Note:
5.1. Module input IN- Prohibit short circuit with output OUT-, otherwise constant current function will be invalid.
5.2. Please make sure that the power of the power supply is greater than the power required by the output load!
5.3. If the module is to be fully loaded with output, the input voltage should be over 8V. When the input voltage is 5V, the output power is about 15W, and the voltage ammeter fails. Module current value 4A, the premise subject to the maximum output power, such as the output 17V, the current should not exceed 2A.
5.4. Module with output short-circuit protection, short-circuit protection module automatically shut down the output, the module can be restored on the power, if your power supply without output current limiting protection, it is recommended that the module input front-end fuse in series to increase the safety factor.
5.5. The module has input under-voltage protection function, the default is about 4.7V. Below this value, the output will be disconnected automatically and the module can be powered on again (note the voltage at the module port. When the input current is relatively large Do not ignore the partial pressure on the input wire).
