Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads

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

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

Industrial batteries translate chemical energy into electricity.

Alternative power generators produce electricity from renewable energy sources, such as wind, flowing water, solar energy and biomass, which create less environmental damage and pollution than fossil fuels.

Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.

Lead acid batteries are made up of plates, lead, and lead oxide with a 35% sulfuric acid and 65% water electrolyte solution.

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.

Industrial sealants are liquid or viscous compounds used between surfaces to contain fluids, prevent leaks, and prevent infiltration of unwanted material. They may also include compounds for filling gaps or seams.

Battery chargers are devices for charging rechargeable batteries.

Rechargeable batteries or secondary batteries contain active materials that can be regenerated by charging. When the energy produced by rechargeable batteries drops below optimum efficiency, secondary batteries may be recharged in a couple of ways, depending upon their construction. 

Computer power supplies convert alternating current (AC) line to direct current (DC) line, needed by the computer.

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

Power resistors are used in power generation and distribution, high-voltage applications, control systems, and other power system applications. They include load banks, grounding resistors, and dynamic braking resistors
