How much power does the Rectifier provide?

The rectifier's primary function in a power system is to convert AC (alternating current) to DC (direct current) and provide a stable voltage output that is commonly used in telecommunications and various equipment. The choice indicating -48VDC (150W) reflects standard operating voltages for many telecom devices and systems.

The reason this voltage level is critical is that -48VDC is commonly used in powering telecommunications equipment, which often has stringent requirements for voltage levels to ensure optimal performance and reliability. The power rating of 150W indicates the maximum output capacity the rectifier can provide, ensuring that connected equipment can operate efficiently without straining the power supply.

Other voltage options like -24VDC and -12VDC are less common for larger telecommunications applications as they typically are intended for lower power requirements. The choice of -48VDC at 75W would not be suitable for systems requiring greater power, particularly in environments with higher energy demands. Thus, the answer of -48VDC (150W) is appropriate for standard telecommunications power systems, reflecting both the necessary voltage and power capacity.
