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.

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

Condition monitoring and machine maintenance services monitor the condition of critical machines, battery banks, power supplies, processes and rotary equipment. They also perform predictive maintenance (PdM) and/or preventive maintenance.

Predictive maintenance (PdM) and condition monitoring systems are used to predict equipment maintenance, and to monitor corrosion, oil condition, bearing wear, overheating and other parameters than can lead to the breakdown of capital equipment.

Optical and light microscopes use the visible or near-visible portion of the electromagnetic spectrum to magnify images of objects.

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

Microscope accessories and supplies are used with many different types of microscopes, including dissection or stereoscopic, compound, and confocal devices.

Microscopes are instruments that produce magnified images of small objects

Industrial batteries translate chemical energy into electricity.

Metallurgical microscopes are used for metallurgical inspection including metals, ceramics, and other materials.

Electron microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition.

Specialty microscopes are designed for specific applications such as metallurgy or gemology. They use specialized techniques or technologies such as acoustics to produce magnification.

Flywheel power systems are high-speed, bore-loaded, carbon fiber flywheel rotors with integrated iron-less motor / generators contained inside a sealed, vacuum housing.

Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.
