DC-DC step-down module 12V5V3A constant current constant voltage step-down plate high voltage input 9-90V72V60V48V36

• Wide input voltage: 9V-90V
• The minimum voltage difference between input voltage and output voltage is 4V (DC9V-90V for 5V output, DC16V-90V for 12V output, and DC30-90V for 24V output)
• Output voltage 24V/12V/5V optional (please contact the customer for customization for other voltages)
• The maximum output current is 3A (i.e. constant current value of 3A, when the customized voltage is greater than 12V, the output current is less than 3A, and the power is not recommended to exceed 30W. 12V and 5V can reach 3A, and 24V is 2A)
• Typical operating frequency: 140KHz
• High efficiency: up to 95%（The smaller the pressure difference, the higher the efficiency）
• Reduce frequency under light load to improve light load efficiency
• Low standby current
• Built in over temperature, over-current, and output short circuit protection
• Built in soft start
• Constant voltage and constant current output
• Working temperature: Industrial grade (-40 ℃ to+85 ℃)
• Module volume: 42 * 30 * 17mm

Usage:

1. First, connect the wires between the module and the power supply,Power on again.Remember! Remember!If the input terminal is wired with electricity, it is easy to cause ignition, especially when the input power supply voltage is high, which may even burn the module's solder pads.

2. After selecting a suitable power source and powering it on, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the equipment.

3. The electrical equipment or load is connected to the output terminal of the module.
