12V/2A (25W) Metal Housing Switching Mode Power Supply For Robotics
A switched mode power supply is an electronic power supply that incorporates a switching
regulator to convert electrical power efficiently. Like other power
supplies, an SMPS transfers power from a source, like mains power
to a load, such as a personal
computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a
switching-mode supply continually switches between low-dissipation,
full-on and full-off states, and spends very little time in the high
dissipation transitions, which minimizes wasted energy. Ideally, a
switched-mode power supply dissipates no power. Voltage
regulation is achieved
by varying the ratio of on-to-off time. In contrast, a linear power supply
regulates the output voltage by continually dissipating power in the pass transistor.
This higher power conversion efficiency is an important advantage of a
switched-mode power supply. Switched-mode power supplies may also be
substantially smaller and lighter than a linear supply due to the smaller
transformer size and weight.
Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight are required.
