6 FAQs about [Solid state power controller wikipedia]
What is a solid state power controller (SSPC)?
Solid state power controllers (SSPC) are semiconductor devices that control power (voltage and/or current) supplied to a load. They perform supervisory and diagnostic functions in order to identify overload conditions and prevent short circuits.
What are the different types of solid state power controllers?
There are several basic types of solid state power controllers (SSPC). AC controllers are designed to switch alternating current (AC) voltages. DC controllers are designed to switch direct current (DC) voltages. AC/DC controllers are designed to switch both AC and DC voltages.
What is a solid-state drive (SSD)?
A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, and solid-state disk. [ 1 ][ 2 ] SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells.
How do you program a solid state power controller?
Programmable solid -state power controllers (SSPCs) can be programmed by a computer, or by a specialized or proprietary programming method. Dropout voltage is the voltage applied to the input at or below where the output is guaranteed to be in the 'off' state. It is also known as the must-release voltage or turn-off voltage.
What is a solid state circuit?
An integrated circuit (IC) on a printed circuit board. This is called a solid-state circuit because all of the electrical activity in the circuit occurs within solid materials.
What are examples of solid state electronic devices?
Other examples of solid state electronic devices are the microprocessor chip, LED lamp, solar cell, charge coupled device (CCD) image sensor used in cameras, and semiconductor laser.
