MAXKGO STM32(MCU) 150V Smart Master BMS + 9V-90V DC-DC Step-down Power Supply Module
DC-DC Step-down Power Supply Module Specifications Input voltage: 9V-90V The minimum voltage difference between the input voltage and the output voltage is 4V (when the output is 5V, the input is DC9V-90V, and when the output is 12V, the input voltage is DC16V-90V. Output voltage: 12V/5V Maximum output current: 3A (that is, the constant current value is 3A, when the customized voltage is higher than 12V, the output current is less than 3A, the power is not recommended to exceed 30W, 12V and 5V can reach 3A.) Typical operating frequency: 140KHz High efficiency: up to 95% (the smaller the pressure difference, the higher the efficiency) Working temperature: industrial grade (-40℃ to +85℃) Module volume: 42*30*17mm Product Advantages Frequency reduction at light load to improve light load efficiency. Small standby current. Built-in over-temperature, over-current, output short-circuit protection. Built-in soft start. Constant volt
