Isolated measurement of current and voltage

In today’s world, efficiency of industrial applications is of increasing importance in order to save energy and money. Industrial applications are controlled by power electronics requiring optimal and accurate regulation of electronic parameters such as current, voltage and power. LEM uses innovative technologies to ensure the high degree of reliability and safety that our customers require.

Typical applications include:

• AC variable speed drives
• Servo motor drives
• Static converter for DC drives
• Battery supplied applications
• Uninterruptible power supplies (UPS)
• Switched-mode power supplies (SMPS)
• Power supplies for welding, medical, mobile telecom, etc.
• Pumps & fans control/monitoring
• Induction cooking
• Gas co-generator
• Elevators
• Forklifts
• Air conditioning and ventilation equipment
• Various converters (solar, wind generators)
• Grid power control
  

With more than 2,500 current and voltage transducers in our portfolio, LEM offers a comprehensive range of accurate, reliable and galvanically isolated devices to measure current from 0.1 A to 20,000 A and voltage from 10V to 6,400V, across a range of technologies. LEM transducers are CE marked in recognition of their electromagnetic compatibility and compliance to EMC standards. The reference standard is EN50178 to comply with electrical performances and environmental constraints.
