MAGNIFIER DC™ Class 6845 Digital DC Magnet Control
After more than 100 years designing crane control, we've got the experience to engineer a Digital DC Magnet Controller with advanced magnet protection and diagnostics for severe mill duty operations and environments. The modular designed Magnifier DC uses the latest IGBT technology and a state of the art PLC to provide full current and voltage control of the magnet in lift, drop, and clean modes. The NEMA 3R control package includes the DC line choke, Regenerative Power Module, and magnet discharge resistor as standard and is sized dimensionally to fit into spaces where contactor magnet controls are used.
Class 6805 MAGNIFIER AC™ Type R Magnet Controller
Class 6805 MAGNIFIER AC Type R, patent pending high performance lifting magnet controller is used for DC magnets rated 10 to 500 Amperes. Typical applications include AC scrap, slab handling and coil handling cranes. The controller is rated for 0º to 55ºC ambient (enclosed) and is suitable for full or partial voltage magnets. The MAGNIFIER AC uses existing LIFT / DROP master switch or push button switches. The MAGNIFIER AC replaces transformer and rectifier, and DC magnet controller.
Class 6815 Type A Lifting Magnet Controllers
These controllers are designed to handle the large inductive currents switched during magnet operations. The Type A Magnet Controllers are designed for 31-130 ampere, generator-powered magnets. Applications include crawler cranes, mobile cranes, locomotive cranes, and DC generator-powered overhead traveling cranes.
Class 6815 Type M Magnet Controllers
These controllers are designed to provide efficient, reliable control of highly inductive current and quick, clean load release, for any manufacturer's full-voltage lifting magnet.
Class 6815 Type MF Magnet Controllers with Fanning Control
The Type MF controllers have an additional slow-discharge circuit, activated by a separate Fan push button. This feature allows the operator to visually control the dropping of all or part of the load, depending on the length the time the push button is held depressed.
