Phoenix Contact's Contactronfamily of solid-state contactors now includes reversing and non-reversingcontactors in a variety of amperages. The contactors can activate or reverse 1-to 18.5 kW-powered ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

The Contactron solid-state reversing contactor from Phoenix Contact combines four functions in a module that’s just 22.5 mm wide (see the figure). Designed for three-phase ac motors up to 4 kW/5 HP in ...

NORD is constantly working to improve and expand on their product offerings. New versions of the NORDAC ON/ON+ are being developed to include safety functions such as SLS, SMS and SSM in addition to ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

In many electrical installations, general-purpose contactors are used to switch the supply voltage to a small dry-type transformer on and off. One common reason this is done is for area lighting ...

The automaker says defective contactors in its electrical motors could come loose, resulting in a loss of power. Lucid previously recalled its luxury Air sedans over a faulty wiring harness connected ...

Ford Motor Company (Ford) is recalling certain 2022 Mustang Mach E vehicles equipped with an extended range battery. The high voltage battery main contactors may overheat.
