DC 9V 12V 24V 36V 48V 120V To 5V 12V Step Down Module Power Supply DC-DC Converter Small Non-isolated Buck Converter

IN+ is the input positive, IN- is the input negative OUT+ is the output positive pole, OUT- is the output negative pole 120V is the input is 160V. 90V input is 100V DC-DC non-isolated step-down power module high voltage input step-down board Wide input voltage: 9V-90V The minimum voltage difference between the input voltage and the output voltage is 4V (the input voltage is DC9V-90V when the output voltage is 5V, the input voltage is DC16V-90V when the output voltage is 12V, and the input voltage is DC30-90V when the output voltage is 24V) Output voltage 24V/12V/5V optional The maximum output current is 3A (that is, the constant current value is 3A, when the customized voltage is greater than 12V, the output current is le than 3A, the power is not recommended to exceed 30W, 12V and 5V can reach 3A, and 24V is 2A) Tyal operating frequency: 140KHz High efficiency: up to 95% (the smaller the differential preure, the higher the efficiency) Frequency reduction at light load to improve light load efficiency Low standby current Built-in over temperature, over current, output short circuit protection Built-in soft start Constant voltage and constant current output Operating temperature: Industrial grade (-40°C to +85°C) Module volume: 42*30*17mm

Instructions: 1. First connect the cable between the module and the power supply, and then power on. Remember! Remember! (If the input terminal is live and wired, it is easy to spark, especially when the input power supply voltage is high, it will even burn the pads of the module). 2. After selecting a suitable power supply, use a or a to measure whether the output voltage of the module is consistent with the voltage required by the device. 3. The electrical equment or (load) is connected to the output end of the module.
