What are the five output voltages of a power supply?
Volt (V) — A measure of potential difference in an electrical circuit. A computer ATX power supply usually provides five separate voltages: +12V, – 12V, +5V, –5V, and +3.3V.
What are the standard input voltages for power supplies?
The typical voltages supplied are: 3.3 volts. 5 volts. 12 volts.
What is the range of High Voltage?
The voltage range between 36 kV and 150 kV is referred to as the high-voltage level. The voltage range between 1 kV and 36 kV is referred to as the medium-voltage level. Any voltage below 1 kV is referred to as the low-voltage level. This is the voltage at which the electricity reaches the power sockets of households.
What is the highest voltage provided by the power supply unit?
The highest voltage provided by a PC PSU is 12 volts so that became the most common input voltage used by the biggest DC/DC converters. A modern CPU has its own converter on the motherboard which converts 12 volts to whatever voltage the CPU requires.
What is the voltage output of EPS?
The »EPS/4000B« is with a variable transformer for a continuously variable output voltage of 0-260V AC at 3A or 4,5A. A further transformer provides a fixed output voltage of 230V AC at 2A. The AC outputs are available on safety sockets on the front panel.
What are the applications of high voltage DC power supplies?
The Hubble telescope, the Cassini-Huygens mission, and other exploratory spacecraft utilize high voltage dc power supplies for everything from vidicon camera tubes and mass spectrometers to radar and laser technologies.
What are high-voltage semiconductor devices?
High-voltage semiconductor devices used for motor control circuits and power supplies include MOSFETs, Insulated Gate Bipolar Transistors, MOS-controlled Thyristors, Power FETs, and Silicon-Controlled Rectifiers. PCB design rules must follow manufacturer guidelines for not exceeding values that can destroy the devices.
What are the PCB design rules for high voltage circuits?
PCB design rules must follow manufacturer guidelines for not exceeding values that can destroy the devices. For example, high voltage circuits may require components that have higher breakdown voltage ratings and the capability to handle higher currents.
Does a high-voltage power grid have to be a power grid?
While a high-voltage design doesn’t always have to be a power grid, you’ll want to be wary when dealing with any electrification designs.
