What is the off position on a power supply?
Power buttons and switches are usually labeled with “I” and “O” symbols. The “I” represents power on and the “O” represents power off.
Which device turns off the supply automatically?
MCB ( miniature circuit breaker) is the device which automatically cuts off the electricity supply during short-circuiting in household wiring.
What is a PSU switch?
The power supply voltage switch, sometimes called the voltage selector switch, is a small switch located on the back of most desktop computer power supply units (PSUs) This switch is used to set the input voltage to the power supply to either 110v/115v or 220v/230v.
What is a power switch IC?
The load switch IC is located between the power supply and the load. The ICs are used for power management to control the power supply to the load. Similar switches can be constructed with mechanical relays and semiconductors such as MOSFET, but load switch ICs can be miniaturized and consume less power.
How does a MCB work?
Whenever continuous overcurrent flows through MCB, the bimetallic strip is heated and deflects by bending. As this mechanical latch is attached with the operating mechanism, it causes to open the miniature circuit breaker contacts, and the MCB turns off thereby stopping the current to flow in the circuit.
What is rocker switch?
Rocker Switches house a button for operation that can be pressed on either end like a seesaw to connect or disconnect an electrical circuit. The name “rocker switch” comes from the rocking motion that the switch makes when the button is pressed. It is also sometimes called a seesaw switch.
What is uncontrolled device?
Power Electronics A classification of power electronic devices Uncontrolled device: diode (Uncontrollable device) has only two terminals and can not be controlled by control signal. The on and off states of the device are determined by the power circuit.
