15W USB adjustable buck-boost usb power supply charging module 5V to 3.3-30V
โมดูลแปลงไฟขึ้นหรือลงให้คงที่ buck-boost power supply รับไฟเข้า 5V จาก USB
หรือ 4-13V ช่อง Input ให้เอาต์พุต 0.5-30V กำลังขับ 15W
มีวงจรป้องกัน short circuit, over current, over temperature, over power, over voltage protection, charging anti-backflow protection
1. Highlights:
• 1.15W power, 2A current, can be used to power the router.
• 2. As a USB input adjustable desktop power supply, you can adjust the output voltage arbitrarily, limit the current 0-2A (wide input 4-13V, wide output 0.5-30V any adjustment, with short circuit protection, short circuit does not burn)
• 3. As a USB charging cable, adjust the charging voltage and maximum charging current arbitrarily (any voltage, with constant current, anti-backflow, to meet the charging of most batteries)
• 4. Multiple protection (short circuit, over current, over temperature, over power, over voltage protection, charging anti-backflow protection)
2. Product parameters:
2.1. Input voltage: 4-13V (When using pad input, pay attention to the positive and negative poles, do not connect AC power)
2.2. Output voltage: 0.5-30V
2.3. Output current: 0-2A (The output current in constant voltage mode is adaptive according to the load size, it is not adjustable. If you set the limit current to 1A, then the load current is greater than 1A, it will automatically enter constant current mode 1A )
2.4. Output power: less than 15W (when the output power is greater than 15W, the output is automatically turned off, and the -OP- is displayed. After reducing the load power, press the ON/OFF button to solve). When the input current is too large, it may be turned off early due to temperature protection.
2.5. Voltage display: resolution 0.1V, factory accuracy ± 0.1V or so (can be manually corrected after comparison with standard voltmeter)
2.6. Current display: resolution 0.01A, range 0-2.2A, factory accuracy ±0.05A; display error is larger when the output current is less than 0.05A, small current within 10-40mA can not be displayed (can be manually corrected, output current Calibration is more accurate when it is greater than 1A, and calibration is not recommended for small currents.)
2.7. Power display: 0.00W-15.0W
2.8. Temperature protection: When the power component temperature is higher than 100 °C, enter the -OT-protection, reduce the load power, press the ON/OFF button to solve (the power will not enter the OT protection for long-term operation within 10W, when the input current is greater than At 3A, it may enter over-temperature protection when working for a long time, even if it does not reach 15W)
2.9. Working current: about 30mA
2.10. Charging anti-backflow: Yes, it can be directly connected to the battery for charging, no need to add a diode
2.11. Short circuit protection: Yes
2.12. Weight: High version 30g, low version 20g
