What is the adjustable power supply?
Adjustable power supply is a power source that does not have a fixed output voltage or current. The output of the power supply can be AC current (AC) or direct current (DC). The output can be adjustable in a wide or narrow voltage, current or both range. The output frequency can also be adjustable when the AC power is powering. Adjustable power sources are often used in scientific laboratories, classrooms and as part of other types of electrical equipment.
The input voltage of the power supply for an adjustable power supply is usually the main voltage of AC current in the area where the delivery is used. It can also be able to handle other common line voltages. For example, many power sources can work from 120 AC (VAC) or 240 VACs. When the DC power supply, this lower voltage is converted to a DC with a rectifier and filtered to provide smoother output. Many DC linear stocks also include power supply circuits that provide accurate stabilized NAPears or current. Linear power supply can also be an adjustable power supply. Common DC laboratory supplies can change from 0 to 30 DC volts (VDC), up to the streams of several amps.
Programmable power is another type of adjustable power. The output voltage of some inventories can be changed by adjusting the voltage to a special input signal. Others may be programmed digitally through common serial or instrumentation interfaces. Programmable power sources are often available in different types that are able to produce DC or AC in different currents, voltage and frequency ranges. The programmable offer is usually relatively sophisticated, including its own processor, as well as monitoring of performance and limiting circuits.
High voltage can also be ensured by an adjustable power supply. Electron microscopes and chemical analysis often use stocks that can change up to 30,000VDC. The current on this type of offer is generally limited to just a few billion. Power on some X -ray devices is often adjustable up to 50,000 VDC.
On some high -level AC power sources, the output frequency is also adjustable. The output output may be instead of a single -phase lowering of the three -phase voltage instead of a single -phase lower voltage. The voltage multiplier can be used with an adjustable power supply to create an even higher DC voltage range.
