Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems.

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.

KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA). Apparent power is the combination of a circuit’s true power and reactive power

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

Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine

CPU coolers are integrated fans and heat sink assemblies packaged to provide optimum cooling performance, often for specific processors.

DC powered pumps use direct current from motor, battery, or solar power to move liquids such as acids, chemicals, lubricants and oil, as well as water, wastewater, and potable water

Power tools encompasses a wide range of devices, frequently motor-driven, for fabrication, assembly, construction, and repair across all industries and applications

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement).

DC power cords are electrical cables that are used to connect two DC devices or a DC device and a DC power source. They are also known as DC power cables

Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.

Industrial fans and industrial blowers and commercial fans and blowers are designed to move air and/or powders in industrial and commercial settings. Typical applications include air circulation for personnel, exhaust or material handling.
