Controls Overview

WEG's large experience on the manufacturing of alternators, added to modern design, production capacity and testing availabilities have resulted in the competitive line of brushless synchronous alternators fitted with electronic voltage regulator.

Available up to 4200 kVA, the synchronous alternators are mainly applied on diesel and gas generator sets as well as on steam, gas and hydraulic turbines.

They are suitable to operate on all emergency or continuous operation generator sets in industrial, commercial, marine, telecommunication, mining areas, in addition to condominiums, irrigation purposes, hospitals and others.

• 3 Pole Normally Open Power Contacts with one built-in Auxiliary Contact (Either Normally Open or Normally Closed)
• 3 Pole Normally Open Reversing Contactors rated AC-4 Utilization Category
• 4 Pole Power Contacts (four Normally Open, or two Normally Open and two Normally Closed)
• Control Relay (multiple auxiliary contacts configurations)

WEG’s control relays are available in multiple auxiliary contacts configuration (up to 8 contacts). Units may be directly mounted on DIN EN50.002 or tightened with screws.

The Combination Soft Starters is an industrial general purpose AC motor soft starter package and designed for simple and quick installation and start-up.

Compact solution for protection and operation of motor circuits up to 100A. WEG’s Manual Motor Protectors combine motor control, disconnect means, short-circuit & motor overload protections in just one component.

The Enclosed Drive Panel is an industrial general purpose AC motor control and protection package. It is designed for simple and quick installation and start-up, requiring only input power and output motor connections.

New generation of WEG frequency inverters for high power ratings, consisting of power units fed through a 6 or 12 pulse input retifier with line voltage from 380 to 690V. The modularity concept is inverted by inserting power units "books" , according to the application demands, makes the CFW-11M suitable for all range of power meeting Normal Duty and Heavy Duty requirements and it increases the VSD reliability as well.

Designed to best suit industrial segments WEG Panels are highly standardized and their modular construction allows easy assembly, installation and maintenance. WEG Panels were designed for various market segments, fulfilling quality and performance requirements compared to the best products available internationally. Availability of Panels NEMA1 to NEMA 4X for all sort of applications regarding 12 and 18 pulses VDSs in Low and Medium Voltage.

WEG has used its leading-edge technology & development capability to design the CSW series. These user friendly and durable pilot devices are available in Industrial Ø22 and Ø30mm & Hazardous Ø30mm versions.

Ideal for applications such as industrial processes, power supply monitoring and level control, these series use high precision electronic circuit with noise immunity.

Designed to guarantee a safe and secure connection for electric conductors. Developed to be used in several applications, offering great quality and performance.

The growing demand for electricity has required large investments in power generation to meet the rate of global development, both in developing countries where the population has gained greater access to consumer goods, and in developed countries, where energy efficiency has been object concern in order to reduce high investments in power generation. These investments, however, besides being planned in the medium and long term, involve the use of increasingly scarce natural resources which are subject to environmental pressures.

In short term, the best way to increase the supply of electricity has been reducing waste and increasing energy efficiency. It is estimated that currently 40% of global consumption of electricity is related to the use of electric motors. Moreover, the application of new technologies has become increasingly common in many industry sectors, bringing deep changes in the form of application and control of electric motors.

Within this context of technological changes and pressures for higher energy efficiency, WEG presents its line of capacitors for power factor correction. These capacitors are manufactured in accordance with National and International Standards such as NBr IEC 60831 Parts 1 and 2, EN IEC 60831 Parts 1 and 2, UL 810, and its supply chain bears ISO 9001 and ISo 14001 certification.The figure below illustrates how the Power Factor Correction works to increase energy efficiency.

Single pole and multi-pole thermal-magnetic miniature circuit breakers (MCBs) in accordance with EN 60947-2, UL 1077 and UL 489. The UMBW is suitable for a variety of applications.
