Magnet’s Carlo Gavazzi WM 50 multi-channel power analysers

Magnet’s range of Carlo Gavazzi multi-channel power analysers and automation products includes WM50 multi-channel power analysers, which efficiently measure main electrical variables, as well as voltage and current harmonic distortions, in a three or single-phase system.

“This flexible device is able to view total and partial active and reactive energy consumption; up to three water, gas and heat totalisers and up to six different energy consumption tariffs,” says Stephen Rogerson, Magnet’s Johannesburg regional manager. “This system, which provides up to 16 alarms, can be integrated with accessory modules to expand its control and communication capacity. Main unit functions are increased with the addition of a maximum of two modules, which include a digital input/output module, an analog input module and a communication module.”

Three analog inputs and six digital inputs and digital outputs are managed via an optional accessory module. This system is able to transmit data to other systems and is also used to log measurements and events.

The WM50 device has been designed for quick configuration and easy installation. Detachable terminals connect to 12-channel current sensors with proprietary cables and clips are supplied with sensors to ensure efficient operation at all times.

The wide backlit LED display clearly shows single and total load measurements, as well as configuration parameter values. Digital communication between current sensors and WM50 device ensures excellent disturbance immunity.

Magnet’s range of Carlo Gavazzi automation products also includes energy-management solutions, including energy meters, current transformers and energy-efficiency monitoring solutions, as well as the VMU range of integrated web server solutions.

These automation systems are suitable for use in diverse industries, including agriculture, building and home automation, conventional and renewable energy, food and beverage plants and HVAC systems. They are also used in packaging and plastics machines, as well as lifts and escalators.

The Magnet Group, which specialises in the supply, implementation and support of electrical equipment, industrial instrumentation and automation, provides a technical and support service throughout Africa, to ensure optimum performance of all components.
