Description: 【High Power】 :boost module Adopt 100V 210A TO 247 large package power tube, with large power margin and good dynamic response. 【Temperature Control Fan】: The hydraulic bearing fan used in the power supply offers an excellent balance between noise levels and heat dissipation. When the load temperature reaches approximately 60 degrees Celsius, the fan automatically turns on, reducing noise, and extending the device's lifespan. 【High quality Isolated Board】: The main power tube insulation board of the power supply uses premium aluminum oxide, which has ten times the thermal conductivity of ordinary insulating pads. 【Versatile Usage】: This DC DC Voltage Step Up Converter can be used to charge your electric bike, boost car batteries, increase voltage, or serve as a power source for other digital devices. 【Three indicator lights】: undervoltage, overcurrent, power indicator, working condition at a glance, input and output are high rate capacitors, output popple is low, heat is small, long time use.MLCC ceramic capacitors are newly added to the input and output, and the output popple is significantly reduced, and it is about 100 millivolts when 48V is converted to 72V4A. Specification: Input voltage: DC10-60V Constant current range: 0.8-20A (+/-0.3A) Input current: 10-30V input voltage, maximum current 30A; 31-60V input voltage, maximum current 25A Static working current: 15mA (when 12V rises to 20V, the higher the output voltage, the quiescent current will increase) Output voltage: 12-90V continuously adjustable Output current: 20AMAX more than 15A, please strengthen heat dissipation Working temperature: -40~+85 degrees Working frequency: 150KHz Size Chart: 13cmx8.4cmx5.2cm/5.12inchx3.31inchx2.05inch Package Includes: 1 boost module Note: Please allow slightly errors due to manual measurement and different monitors.
