DC step-down power module 9-120V100V96V84V72V24V Wide voltage input to 5V12V high current 3A:
The product description:
Wide input voltage: 9V-120V
Minimum pressure difference between input voltage and output voltage 4V (input voltage is DC9V-120V when output is 5V and input voltage is DC16V-120V when output is 12V)
Output voltage 12V/5V Optional (For other voltages, please contact customers for customization)
Maximum output current 3A(constant current value 3A, when the customized voltage is greater than 12V, the output current is less than 3A, the power is not recommended to exceed 30W)
Typical operating frequency: 140KHZ
High efficiency: up to 95% (the smaller the pressure difference, the higher the efficiency)
Light load frequency reduction, improve light load efficiency
The standby current is low
Built-in over temperature, over current, output short circuit protection
Built-in soft start
Constant voltage constant current output
Operating temperature: Industrial grade (-40℃ to +85℃)
Module volume: 40*30*19mm
1. Connect the cable between the module and the power supply before powering on. Remember that! (If the input terminal is wired, it is easy to spark, especially when the input power voltage is high, it will even scorch the pad of the module)
2. After powering on a proper power supply, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the required voltage.
3. Electrical equipment or load is connected to the output end of the module.
