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

Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits

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

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

Noise generators and sources are used to produce noise outputs for testing radio frequency (RF) equipment

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).

Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps. They provide precise positioning and ease of use, especially in low acceleration or static load applications.

Thermal cyclers are laboratory instruments capable of generating and maintaining specific temperatures for a defined period of time.

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action.

Video switchers control video display sequences for multiple camera systems.

Overload relays prevent an electric motor from drawing too much current and overheating; includes thermal and solid state overload types.

Analog I/O devices process analog signals (e.g., output of transducers) and output the results in analog format.

Dry material (powders) level switches are used to measure levels of dry, solid materials via an electrical switching action.

Electrometers are instruments that measure electric charge and/or electric potential difference.

Smoke detectors are designed to sense the products of combustion. Common types include ionization chambers and photoelectric devices.
