Adjustable Direct Current Voltage Regulator Module Constant Voltage and Constant Current Power Supplying Module LCD Large Display Step-down Module with Multiple Protections This step-down module has large LCD display, the working state is clear at a glance, easy to operate. In the operation interface, short press the knob, power (W) capacity (Ah) energy (Wh) time (h) will displays in turns. When the power is off, the set voltage and current are displayed in turns. Support setting voltage and current, quick setting voltage or current, parameter setting (maximum capacity, maximum energy, maximum running time), input and output voltage display, power/capacity/energy/time viewing, with lock function. Suitable for computer power conversion, DIY desktop small power supplies. Features: LCD Display: Large LCD display, the working state is clear at a glance, easy to operate. In the operation interface, short press the knob, power (W) capacity (Ah) energy (Wh) time (h) will displays in turns. When the power is off, the set voltage and current are displayed in turns. Multi-functional Design: Support setting voltage and current, quick setting voltage or current, parameter setting (maximum capacity, maximum energy, maximum running time), input and output voltage display, power/capacity/energy/time viewing, with lock function. Rich Interfaces: Equipped with PD interface, automatic activation after inserting and output 20V high voltage; spare expansion port; power battery interface; 5.5 * 2.5 direct current plug, input voltage 6.0-70VDC (Note: the input voltage can not exceed the input voltage ranges of the power supplys); unplugged terminals;  intelligent temperature control fan interface. Multiple Protections: With input anti-reverse connection protecting, output short circuit protecting, input undervoltage protecting, overvoltage protecting, overcurrent protecting, over temperature protecting, over power protecting. Efficient Heat Dissipation: The the front housing has invisible air inlet, with reasonable air out of the cooling structure, which can effectively take away the heat inside the housing, so that the power supplying efficient and reliable operation Wide Applications: Suitable for computer power conversion, DIY desktop small power supplys.
