Ohio's magnet controllers feature robust contact tips and heavy-duty movable parts. Parts interchangeability between Ohio controllers ensures that customers need a minimum of controller-related inventory. Ohio's controllers were designed to maximize worker productivity, with options for both an automatic drop and a manual drop.
Automatic Drop: In automatic drop mode, the controller automatically senses the precise amount of reverse current required to clear the magnet load. The reverse current adjustment provides for a fast, clean drop of the magnet over a complete range of magnetic material with one movement of the master switch or push button. The drop circuitry is made to function by a set of adjustable timers that control drop time.
Manual Drop: In manual drop mode with low-amperage magnets, workers gain precise control over plates and the ability to dribble scrap. The controller allows for partial dropping of the load by controlling the amount of reverse current to the magnet through discharge resistors. A Drop position on the master switch or push button is spring-returned to Off, giving the operator complete control of the drop cycle.

Model RD2A Auto / Manual Drop Magnet Controller
Model RD3A Ohio Duty-Cycle™ Magnet Controller
All electromagnet controllers serve the same functions of energizing and de-energizing the magnet. They dissipate the stored inductive energy in the magnet coil, apply a controlled amount of reverse current to de-magnetize the magnet, and turn "off" completely the power to the magnet.
The Model CDS magnet controller is the smallest controller in Ohio's line, targeted at locations with space constraints, to manage magnets requiring up to 20 A.

The Model MC-1A Ohio Duty Cycle™ magnet controller is a wide range controller used for magnets requiring 115 / 230 volt DC operation and 20 to 100 cold magnet amps. The Model 1.5A and MC-2A controllers offer heavy-duty magnet control for magnets whose cold current ranges from 70-130A and 100-150A, respectively.

The Optimizer™ magnet controller offers wide-ranging control for all magnets through solid-state, microprocessor-driven IGBT, enabling user-adjustable parameters and choices among multiple, standard voltage DC operation. Through its operating modes and existing 2- or 3-position operator controls, the Optimizer™ offers optimum lift (100% voltage applied in less than 50 ms), hold (lift current automatically reduced to optimized holding current), dribble (magnet current slowly reduced), drop (instant discharge through IGBT discharge, eliminating voltage spikes), and clean (instant reversal of magnet current, eliminating voltage spikes). The adjustable parameters allow Optimizer™-controlled magnets to run cooler and more efficiently, improving productivity, profitability and longevity. Choose from among three models: M350; M200; and M100.
The Model RD1W automatic controller is a “wide-range” magnet controller used for magnets from 100 A down to 20 A, cold current. A reverse current adjustment provides adjustable drop time on the load over a complete range of magnetic materials with one movement of the master switch or push button. The RD1W controller uses many parts interchangeable with both higher- and lower-range controllers for lower inventory costs.

The Model RD3A magnet controller is Ohio’s highest-rated controller, featuring robust contact tips and heavy-duty movable parts. RD3A’s amperage rating allows this controller to operate Ohio’s and competitors’ largest magnets. And, of course, it cuts inventory costs since all parts are interchangeable with Ohio's larger controllers.
Ohio offers a variety of operator control switches to meet the personal preferences of your workers. In addition to a push-button control switch, Ohio offers a standard lever-type switch and reduced voltage packages.
