Voltage and current signal conditioners amplify or modulate voltage or alternating current (AC) and/or direct current (DC) signals. A voltage conditioner maintains a constant output voltage to industrial machinery and production equipment. A current signal conditioner maintains a constant current output to sensitive electronic devices such as computers and computer peripherals. Voltage and current signal conditioners that provide high voltage conditioning or produce a specified conditioner voltage are also available. Manufacturers, distributors, and suppliers of voltage signal conditioners and current signal conditioners are located across the United States and around the world. They meet a variety of regulatory requirements and quality standards.

There are many different types of voltage and current signal conditioners. A line conditioner regulates line voltage to minimize damaging voltage spikes or sags. It also provides surge protection for incoming power, data or phone lines, or hardwired systems. Since the incoming AC line voltage varies, the DC output voltage of a power supply can vary as well. A line voltage conditioner is used to keep the line voltage that is sent devices stable at the specified 120 V or 240 V, depending on the range that the device can tolerate. Voltage signal conditioners and current signal conditioners include surge suppressors, line conditioners, and uninterruptible power supplies (UPS). Surge suppressors and uninterruptible power supplies that designed for home computer equipment are typically inexpensive and not suitable for protecting more sensitive devices.

Voltage and current signal conditioners differ in terms of features. Some voltage signal conditioners and current signal conditioners provide signal conditioning for sensors and measurement equipment, ensuring accurate gathering of data in a process monitoring or laboratory setting. Other voltage signal conditioners and current signal conditioners provide filtering of electromagnetic interference (EMI) or radio frequency interference (RFI). Though typically not damaging to electronic devices, EMI and RFI noise can disrupt sound and picture quality.
