Features: Have good heat dissipation effect and high output power (the power can reach about 1800W when 48V input and fan are added). With the liquid bearing fan, the noise and heat dissipation are well balanced. When the load is light, the fan does not rotate, and the fan automatically turn on after the load temperature is about 60 degrees. Can effectively reduce noise and prolong service life. The insulation board of the main power adapter is selected from alumina, and its thermal conductivity is 10 times that of insulation pad. Adopt 100V 210A TO-247 large package power adapter, with large power margin and good dynamic response. Double large-size magnetic adapter adopts four 1.2 copper enamelled wires in parallel, with low heating and high efficiency. Specifications: Component:Plastic Size:Approx.130x52mm/5.12x2.05inch Input: 10-60V Output current: 20A If more than 1, please strengthen heat dissipation (related to the input and output pressure difference, the pressure difference is large, the output current is small) Constant current: 0.8-20A (+/-0.3A) Operating frequency: 150KHz Package Includes: 1Pc Power module note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
