DC-DC Buck Step Down 9V-90V 84V 72V 60V 48V 36V to 12V 3A Power Supply Module
Features:
Minimum voltage difference between input voltage and output voltage 4V
Output voltage: 12V optional (other voltages please contact customer order)
Maximum output current: 3A (ie, constant current value is 3A. When the customized voltage is greater than 12V, the output current is less than 3A, and the maximum power is recommended not to exceed 30W)
Typical operating frequency: 140KHz
High efficiency: up to 95% (lower differential pressure, higher efficiency)
Lighter frequency reduction to improve light load efficiency
Small standby current
Built-in over-temperature, over-current, output short circuit protection
Built-in soft start
Constant voltage constant current output
Operating temperature: Industrial grade (-40°C to +85°C)
Module size: 42*30*17mm
Instructions:
1, first connect the connection line between the module and the power supply, and then power on. Remember! Remember! (If the input has live wiring, it is prone to ignition, especially if the input power supply voltage is high, it may even burn the module's pad).
2. After selecting the proper power supply, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the device.
3. Use electrical equipment or (load) to connect to the output of the module.
