Company profile

Janitza, a German enterprise was founded in 1961 and is since almost 50 years active in the field of development and production of systems for efficient usage of electricity, energy measurement and cost reduction.

Janitza electronics GmbH is nowadays globally well known as supplier of smart energy management systems (ISO 50001), energy measurement devices, class-A-power quality monitoring systems, power analyzers, power factor controllers, and power quality solutions, such as PFC-systems and harmonic filters.

Our products, systems and services of Janitza extend from the measurement, e.g. data acquisition via the energy management to solutions for improving power quality.

The UMGs, GridVis® software and components unite 3 solutions - energy data management, power quality monitoring and residual current monitoring (RCM) - within a common system environment
