We are a manufacturer of electronic components, electronic modules for a large number of products.We are the factory!With more than 10 years of PCB development experience, the product quality is good, the price is excellent.A large number of wholesale sales of global buyers, welcome to purchase.
1. Numerically controlled voltage and current adjustment, convenient and fast, industrial quality, high precision, can be directly used in engineering projects;
2. Using professional power LCD, clear interface, minimalist operation, and almost perfect protection mechanism;
3. Hardware protection: the input terminal is protected against reverse connection, and the reverse connection will not burn; the output terminal is short-circuit protected, and the short circuit will not burn; the output terminal is anti-backflow, and there is no need to add an anti-backflow diode when charging the battery;
4. Software protection: over voltage protection (OTP), over current protection (OCP), over power protection (OPP), over temperature protection (OTP), input under voltage protection (LVP);
5. The default adjustment voltage or constant current value can be set, which can be adjusted quickly in various
6. Voltage and current can be locked to prevent misoperation!
7. Fully used materials, stable performance and wide range of uses.
1. Product parameters:
Input voltage: DC5.0V-30V (lower voltage protection LVP is available below 4.7V, it is recommended that the input voltage is higher than 7V, when the input voltage is lower than 7V, the output power will be reduced, the lower the input voltage, the smaller the output power)
Output voltage: DC0.6V-30V
Output current: 0-4.0A
Output power: 35W under natural heat dissipation, up to 50W under air cooling
Voltage accuracy: ±0.5%+1 word, resolution: 0.01V, factory calibrated accuracy
Current accuracy: ±0.8%+3 words, resolution: 0.001A, factory calibrated accuracy
Conversion efficiency: about 88%
Soft start: Yes
Input reverse connection protection: Yes, reverse connection does not burn
Backflow prevention at the output: Yes, it can be directly connected to the battery
Output short circuit protection: Yes, can be directly connected to the output terminal
Temperature protection (OTP): Yes, 100℃
Working frequency: 180KHZ
Short press the UP/DOWN button, the voltage is adjusted by default, and long press (rapid increase/decrease) is supported;
Long press the SET button for 1 second to adjust the constant current value (current limit value);
SET and CV flash when adjusting the voltage, and SET and CC flash when adjusting the current, which is very intuitive;
Short press the SET button to switch and display current A/power W/capacity Ah/energy Wh/time h;
Short press the ON/OFF button to turn on/off the power output;
Long press the ON/OFF button for 2 seconds to switch the display of input and output voltage.
After it is set to CC, the constant current value is adjusted by default. When driving the LED, fast dimming can be realized by rotating the encoder point, which is very convenient!
Long press the SET button for 3 seconds to enter the setting interface;
Note: After the product is protected, the output will be turned off and the LCD will display the corresponding protection code (LVP/OVP/OCP/OPP/OAH/OPH/OHP). The power chip itself also has various protections. If the chip itself is protected, OEP is displayed.
2. Operation instructions for setting interface:
2.1. Long press the SET button for 3 seconds to enter the setting interface;
2.2. Adjust the size of the parameter through the UP/DOWN button, support long press (rapid increase/decrease), short press the SET button to switch the parameter to be adjusted;
2.3. In the maximum capacity (OAH)/maximum energy (OPH)/maximum operating time (OHP) interface, short press the "ON/OFF" button to select the corresponding function on or off, if it is off, it will display "---- ";
2.4. In the maximum capacity (OAH)/maximum energy (OPH) parameter interface, long press the "ON/OFF" button to select the capacity range (9.999Ah/99.99Ah /999.9Ah/9999Ah, 9.999Wh/99.99Wh /999.9Wh/9999Wh );
2.5. After setting the parameters, press and hold the SET button for 3 seconds to exit the setting interface, and the setting parameters are automatically saved;
3. This product has a lock function:
Long press the SET button for 5 seconds to lock the set voltage and current to prevent misoperation! After locking, press and hold the SET button for 5 seconds to unlock!
