รายละเอียดสินค้า
"Product highlights:
1. NC regulates voltage and current, which is convenient, fast, industrial quality and high precision, and can be directly used in engineering projects.
2. Using professional power supply liquid crystal, the interface is clear, the operation is very simple, and the protection mechanism is almost perfect.
3. Hardware protection: input anti-reverse connection protection, reverse connection non-burning; output short circuit protection, short connection non-burning; output anti-reverse irrigation, charging the battery without additional anti-reverse diode;
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 voltage or constant current can be set, which can be quickly adjusted in various applications.
6. Voltage and current can be locked to prevent misoperation!
7. Full material, stable performance and wide use.
1. Product parameters:
Input voltage: DC 5.0V-30V (below 4.7V with under-voltage protection LVP, it is recommended that the input voltage is higher than 7V, when the input voltage is lower than 7V, the output power will decrease, the lower the input voltage, the smaller the output power).
Output voltage: DC 0.6V-30V
Output current: 0-4.0 A
Output power: 35W under natural heat dissipation and 50W under air cooling
Voltage accuracy: ±0.5%+1 byte, resolution: 0.01V, factory calibrated accuracy
Current accuracy: ±0.8%+3 bytes, resolution: 0.001A, factory calibrated accuracy
Conversion efficiency: about 88%.
Soft Start:Yes.
Input Reverse Connection Protection: Yes, Reverse Connection No Burning
Output anti-backfilling: Yes, it can be directly connected to the battery.
Output Short Circuit Protection: Yes, it can be directly connected to the output terminal.
Temperature Protection (OTP): Yes, 100℃.
Working frequency: 180KHZ
After setting to CC, the constant current value is adjusted by default. When driving the LED, the fast dimming can be achieved by rotating the encoder, which is very convenient.
2. Setting up interface operation instructions:
2.1. Press the key of rotary encoder for 3 seconds to enter the setting interface.
2.2. By adjusting the parameters of the rotary encoded potentiometer, it can support fast rotation (fast increase/decrease), and switch the parameters to be adjusted by pressing the key of the rotary encoded potentiometer.
2.3. In the maximum capacity (OAH)/maximum energy (OPH)/maximum running time (OHP) interface, press the ""ON/OFF"" button to select the opening or closing of the corresponding function, and if it is closed, display ""--"";
2.4. In the maximum capacity (OAH)/maximum energy (OPH) parameter interface, long press the ON/OFF button to select the range of capacity (9.999Ah/99.99Ah/9999999Ah, 9.999Wh/99.999Wh/99999999Wh);
2.5. After the parameter setting, press and hold the encoder potentiometer key for 3 seconds to exit the setting interf
