A low noise HV power supply is capable of providing DC outputs at voltage levels exceeding hundreds of thousands of volts. Some of these devices have an adjustable output, which is regulated through either a manual interface, or a remote computer system. They are often employed in highly specialized environments, such as medical science, video, telecommunications, and imaging. When choosing which type of these power supplies is best for a given situation, some considerations to remember are input/output voltage, output specifications, style, interface type, and the environment for which it is intended.

There are several types of low noise hv power supply user interfaces available. An analog front panel allows for manual manipulation of the device's specifications by the user. A digital front panel allows the same basic type of interaction, but with a digitally regulated precision. A computer interface is operated via a stand alone unit that is wired to the low noise hv power supply. This allows a great degree of control, as it can be utilized to automatically regulate the device, or provide a remote means for the user to directly interface with it.

Low Noise HV Power Supply Signal Strength

These devices employ low noise technology through the use of an amplifier. An amplifier is a component that increases the strength of a signal. It does this by shaping the output to match the power from a power supply. An ideal amplifier would have an output equal to the original input. However, this is nearly impossible in all but the smallest systems. This is due to dissipation, which is instigated by excessive heat, and exacerbated by noise in the system.

Noise is defined as any fluctuations or disturbances within a current that can distort or diminish the signal. A low noise hv power supply uses an amplifier to isolate weaker portions of a signal, and increase their strength through amplification. This filters out any disturbances that would otherwise cause dissipation and disturbance, strengthening the overall flow.
