DC16-120V 12V 3A Step Down Module Power Supply DC DC converter Non-isolated Buck Converter
Product parameters
1. wide input voltage: 9v-120v
2. the minimum voltage difference between the input voltage and the output voltage is 4V (the input voltage is dc9v-120v when the output voltage is 5V, and the input voltage is dc16v-120 when the output voltage is 12V
V)
3. output voltage 12v/5v is optional (please contact the customer for other voltages)
4. the maximum output current is 3A (that is, the constant current value is 3a. When the customized voltage is greater than 12V and the output current is less than 3a, the power is not recommended to exceed 30W)
5. typical working frequency: 140khz
6. high efficiency: up to 95% (the smaller the pressure difference, the higher the efficiency)
7. reduce the frequency of light load and improve the efficiency of light load
8. low standby current
9. built in over temperature, over-current and output short circuit protection
10. built in soft start
11. constant voltage and constant current output
12. working temperature: industrial grade (-40 ℃ C to+85 ° ℃)
13. module volume: 42*30*19mm
Method of use
1. Connect the connecting wire between the module and the power supply before energizing. Remember! Remember! (if the input terminal is connected with electricity, it is prone to sparking, especially when the input power supply voltage is high, it will even scorch the bonding pad of the module),
2. Use a multimeter or voltmeter to measure the voltage after the appropriate power supply is powered on
Whether the output voltage of the gauge block is consistent with the voltage required by the equipment. 3. The electrical equipment or (load) is connected to the output end of the module.
