Another key component of a “Retain 48V” system is the power storage device, which can be a battery, supercapacitor, or other type of energy storage device. This component helps to maintain power to critical systems by storing energy when the main power source is available and releasing it when the power source is disconnected. The power storage device can be sized to provide a specific amount of energy, depending on the requirements of the application.
How does the “Retain 48V” concept impact the design of electrical systems?
The “Retain 48V” concept can significantly impact the design of electrical systems, as it requires a different approach to power management and system architecture.
