DROK DC-DC تنحى محول الجهد الحالي المستمر 4-38 فولت إلى 1.25-36 فولت 12 فولت 24 فولت باك فولت منظم 5A 75 واط عالية الطاقة LED CC وحدة سائق لشحن بطارية ليثيوم أيون الكهربائية
Limited-current/short-circuit/over-temperature/input reversed connection protection all allows safe usage
Work as buck converter, high-power LED constant amp driving module and battery charger with USB connector
With two working modes of constant volt and constant amp which would be indicated by the RED LED indicator
Can set float volt&charging amp if being used as lithium battery charger with green LED lights in full-charge
A large area of copper in its back to strengthen heating radiating; low ripple, high efficiency and large power
وصف
Parameter
Input voltage: 4-38V
Output power: 75W(Max)
Transfer efficiency: 96%(Max)
Output current: adjustabel;5A(Max)
Output voltage: 1.25-36V constantly adjustable
Input reverse connection protection: NO
Short-circuit protection: YES(limited current of 8A)
Over-temperature protection: YES(item will stop output automatically)
How to set current limits:
1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want.
2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-voltage potentiometer to make output current reach preset over-current protection value. (If the current value multimeter displays is 4A, the maximum current of the module only can be up to 4A; when the current reach 4A, constant-voltage constant-current red indicator light is on, or the light is off)
LED indicator light:
1. Red light is on in constant current status and off in constant voltage status.
2. Blue light is on when charging and off when full-charging
3. Green light is on when full-charged.
