Versatile voltage transducers

October 2010 Electrical Power & Protection

Geneva-based LEM has expanded its range of high accuracy voltage transducers to measure from a few volts up to 6400 VAC or DC and everything in between. Two technologies are used to achieve these measurements: closed loop Hall technology and voltage divider with optical isolation.

Typical applications include railway traction, AC variable speed drives, servo motor drives, windmills, battery supplied applications, ie, electric vehicles, forklift trucks, solar power installations, uninterrupted power supplies, switch mode power supplies and power supplies for welding applications.
