12V to 24V Step Up Converter 9~20Vdc to 24Vdc 0~4A MAX 0~96W Adaptive DC to DC Boost Converter Transformer Voltage Module Regulator Waterproof Power Supply(9~20V Input/24V 0~4A MAX Adaptive Output)

12V to 24V Step up Converter：Input voltage range: DC 12V (9 - 20)V; Output voltage: DC 24V; Output current: 0~4A MAX(Adaptive). Output power:0~96W MAX(Adaptive).;
Multiple protection & High and stable output: DC 9~20V to 24V Converter With Overcurrent protection, Overvoltage protection, Over temperature protection, Short circuit protection. High-quality components, 96% conversion efficiency, super power and long service life. Buck Converter.
The working principle of the converter: the input power (voltage * current = power.) must be greater than the output power (because the conversion efficiency of the power converter is 96%). Note: The larger the input current, the better, the greater the current the converter bears, the smaller the load, and the lower the heat output. (Input large current will not attack the module)
Adaptive Converter Output Current: Our converter current is adaptive. It is recommended that you choose a converter with a larger current than the output device. The more space left for the converter, the better the heat dissipation and lifespan.
Flame-retardant plastic shell: Flame-retardant material shell improves flame-retardant, toughness and strength. Epoxy resin potting: better heat conduction and heat dissipation, IP68 protection level, waterproof, dustproof, and shockproof
