Devices that produce constant voltage and stabilize voltage levels and signals.
Power Supply and Conditioning Categories

AC Power Sources (246 suppliers)

AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltages, current and frequency levels.

Ballasts (404 suppliers)

Ballasts are electrical devices that condition the line voltage (amplitude, amperage and waveform) to operate fluorescent and HID lamps. Basically they serve two functions: to provide the starting kick, and to limit the current to the proper value for a particular lamp.

Board Mount Voltage Multipliers (14 suppliers)

Board mount voltage multipliers are AC-to-DC conversion devices mounted to a printed circuit board (PCB) that produce a high potential DC voltage from a lower voltage AC source.

Current Sources (87 suppliers)

Current sources provide reliable current for electrical component testing and for powering specialized components.

DC Power Systems (133 suppliers)

DC power systems provide continuous DC power through multiple outputs.  Most DC power systems include a battery backup, temperature compensation, and other features.

Electric Vehicle Chargers (38 suppliers)

Electric vehicle (EV) charging stations are devices designed for charging electric vehicles. Charging stations are designed either for home or public use and may have different charging rates.

EMI Filters and RFI Filters (341 suppliers)

Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals of unwanted noise by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI.

Fuel Cells (118 suppliers)

Fuel cells produce electricity and heat electrochemically by combining oxygen from the air with a fuel, preferably hydrogen, from methanol, natural gas, or petroleum.  Reformers are often used in conjunction with fuel cells.

Phase Converters (60 suppliers)

Phase converters transform single-phase power into three-phase power for the operation of industrial motors, pumps, and other equipment.

Photovoltaic (PV) / Solar Combiners (19 suppliers)

Photovoltaic (PV)/solar combiners provide a cumulative voltage from PV panels and PV panel strings, before routing power to a controller or inverter. Off-grid and large grid-tied systems benefit from the overcurrent protection and convenience of these devices.

Plasma Generators (11 suppliers)

Plasma generators are special generators that produce the needed RF power to ignite and maintain plasma in plasma chambers and similar devices.

Power Amplifiers (160 suppliers)

Power amplifiers deliver a specific amount of AC power to a load. They are used in audio frequency and radio frequency applications.

Power Distribution Units (PDU) (395 suppliers)

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices. 

Power Factor Correction (PFC) Products (88 suppliers)

Power factor correction (PFC) products are used to configure and correct the power factor in power systems.

Power Filters (146 suppliers)

Power filters are electronic circuits designed to locate and eliminate surges, harmonic transient currents, spikes, and other unwanted signals.

Power Frequency Converters (108 suppliers)

Power frequency converters take electrical input power at one frequency and voltage and provide electrical output power at a different frequency and at a different or equal voltage.

Power Inverters (843 suppliers)

An inverter is an electrical device that converts direct current (DC) to alternating current (AC).

Power or Line Conditioners (198 suppliers)

Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment.

Power Rectifiers (249 suppliers)

Power rectifiers are electrical devices that convert alternating current (AC) to direct current (DC). They are an integral part of telecom rectifiers for the telecommunications industry, and in battery chargers, DC power systems, and other power system devices.

Power Strips (211 suppliers)

Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection.

Power Supplies (6,475 suppliers)

Power supplies are devices that produce AC or DC power.

RF Generators (91 suppliers)

RF generators and high frequency power supplies provide the power required for plasma generation, induction heating, and radar or communications applications.

SCR Power Controllers (99 suppliers)

Silicon controlled rectifier (SCR) power controllers precisely regulate output power to resistive heating loads such as industrial furnaces and ovens. They generally operate on either zero-crossing or phase angle control.

Solar Charge Controllers (35 suppliers)

Solar charge controllers are devices that manage batteries in a photovoltaic array. They extend battery life by ensuring that batteries are not overcharged or over-discharged.

Solar Panels (117 suppliers)

Solar Panels are modules built with a collection of solar cells and are used for the production of DC voltage and current directly from the sun energy.

Solar Trackers (15 suppliers)

Solar trackers are devices that determine the position of the sun relative to its own position on Earth's surface, and it adjusts integrated equipment for optimal sunlight reception. It's most common usage is in conjunction with PV collection panels. 

Uninterruptible Power Supplies (1,536 suppliers)

Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable.

Voltage Multipliers (10 suppliers)

Voltage multipliers are AC-to-DC conversion devices that produce a high potential DC voltage from a lower voltage AC source. They are used to produce high voltages where low current is required. 

Voltage Regulators (183 suppliers)

Voltage regulators are power converters that provide voltage control capabilities. They accept a voltage that varies over a given range and generate an output voltage that does not vary.
