Dasiter 600W High Power DC to DC Boost Converter DC 12-60V to 12-80V Boost Module Board Step-up Transformer

【DC to DC Boost Converter】600W high power booster module, wide voltage input: 10V ~ 60V, 12V ~ 80V adjustable wide voltage output.
ultra-low input and output pressure difference..
【DC to DC Boost Converter】Specifications: Radiator bottom plate thickness 5mm, tooth height 21mm, length 85mm, width 63mm, booster plate fixed above the radiator, rational design, integrated design of radiator and booster plate, convenient for users to use directly, use long screws fixed directly..
【DC to DC Boost Converter】The module has a constant voltage and constant current function, but it is a non-isolated boost mode, due to its characteristics, the constant current range depends on the input and output voltage and load..
【DC to DC Boost Converter】Please Power on the module first, then connect the load, which is especially important in high-power loads.
the input voltage should be stable, especially when some low-voltage (12V) input power supply is connected to the load voltage, it will fall below 10V, and it is easy to break down the power tube at this time..
【DC to DC Boost Converter】Two or more modules can not be used in parallel input and output, otherwise the current limit function will be invalid.
