Voltage Converter 24 V to 12 V: DC voltage 24 V input, DC voltage 12 V output, maximum current 20 A 240 W / 5 A 60 W. The aluminium shell and organic silicone are waterproof, dustproof and shockproof. Suitable for various harsh environments.
Synchronous voltage technology: the heat of the 12 V anti-pressure device is extremely low, the performance is sufficient and the output is stable. The rectifier has a low loss and the efficiency of the downward module is up to 90% to meet the requirements for rectifying low voltage and large currents.
Safe and reliable: the voltage stabiliser 12 V has automatic protection functions such as overvoltage, overload, low voltage and over temperature. The DC converter uses a waterproof casting technology design, provides comprehensive protection and is more stable and reliable.
Low heating: Multiple electrolytic capacitors with wave pattern and high impedance, iron silicon aluminium magnetic rings are usually durable and heat only slightly. By pouring electronic parts into the case, great stability and vibration resistance are achieved and the life of the DC DC converter 12 V is improved.
Application: Voltage regulators are widely used for industrial electrical devices with appropriate voltage and used for screens, fans, vehicles, robots, photovoltaic modules, CNC equipment, LED lights and printers.
