3A/5A/12A DC DC Buck Converter CC CV Power Supply Module Adjustable Voltage Regulator Voltmeter Step-Down Power Module with LCD Display
Features:
1. Crystal shell, beautiful design, good touch texture of buttons, LCD display, clear data.
2. Five parameters including capacity display, input and output voltage display, output current display, power display, capacity display.
3. High efficiency above 95%, high current, low heat generation, output voltage 1.2-32V can be adjusted arbitrarily, constant current value can be adjusted from 0-12A, suitable for high-power LED constant current drive, lithium battery charging, etc.
4. All kinds of protection, anti-reverse connection--reverse connection will not burn, anti-backflow--directly connect to the battery, do not worry about battery backflow and burn the module, no need for another series of diodes, overcurrent protection-output short-circuit does not burn, and the rechargeable battery is limited Stream Safe.
Specifications:
Input voltage: 5-27V/6.5-36V/5.3-32V
Output voltage: 1-24V/1.2-32V/1.2-32V
Output current: 3A/3.5A/8A
Working current: 30mA/30mA/25mA
Output power: 30W/50W/120W
ZK-J3X:
Voltage display: resolution 0.01V, factory accuracy ±0.1V
Current display: resolution is 0.001A, range is about 0-3A, factory accuracy is about ±0.05A; when the output current is less than 0.05A, the display error is large, and the small current within 10-40mA cannot be displayed (if the accuracy requirements are high, it can be combined with the standard Manual calibration after ammeter comparison, calibration is more accurate when the output current is greater than 1A)
ZK-J5X:
Current display: resolution 0.005A, range about 0-4.5A, accuracy ±0.05A
Voltage display: resolution 0.05V, range 1.2-32V, accuracy ±0.1V
ZK-JVA-12KX:
Voltage display: resolution 0.05V, range 0-32V
Current display: resolution 0.01A, range 0-12A
Capacity display: resolution 0.001Ah, range 99.99Ah (can be reset by long pressing the '-' key, it will be automatically saved after power-off, and automatically accumulated after power-on. After reaching 99.99Ah, it is saturated and needs to be reset manually)
Conversion efficiency: 95%
Short circuit protection: yes
Input reverse polarity protection: yes
Output anti-backflow: yes (ZK-J5X, ZK-JVA-12KX do not have)
Note:
1. Due to the light and screen difference, the item's color may be slightly different from the pictures.
2. Please allow 1-3cm differences due to manual measurement.
Package Included:
1x Step-Down Power Module
1x Shell
