Variable Frequency Drives A variable-frequency drive (VFD) (also termed adjustable-frequency drive, variable speed drive, AC drive, micro drive or inverter drive) is a type of adjustable speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.

Cables These connecting and control cables are used in machines and plants for instrument engineering. These cables are universally applicable, resistant to many oils and chemicals and are highly flexible and sturdy. There are a wide range of flexible cables such as color coded, number coded, copper screened, steel wire braided, polyurethane cables, neoprene rubber cables, robotic cables, super flexible cables with minimum bending radius and all types of weather resistant cables.

Attenuator An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than 1.Attenuators are usually passive devices made from simple voltage divider networks.

Circuit Breaker A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

Insulators An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors or conductors.

Trivector Meter The Trivector meter is a measuring instrument which measures the kW, kVAr, the kVA of a power line. These instruments can measure both power as well as energy. Trivector meters are normally used in substations and to measure the power flowing through the feeders. They are used for billing power drawn by industrial customers. The Trivector enables the simultaneous measurement of different electrical parameters which enables accurate assessment of the power consumed.

Load Cells A load cell consists of a metal element that is introduced to a change through tension (pulling apart) or compression (pushing together) forces, and interior strain gages that sense this change, which is sometimes referred to as deflection.

Relays A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up or other overloading conditions that result in measurable increases in motor current.
