Our magnet control rectifier product is produced as 220 VDC or 120 VDC for magnet lift devices. Application powers vary between 3 kW and 60 kW. The magnet control rectifier can be easily operated by the user with the remote control Start-Stop remote control, and lifting and dropping operations are performed safely. In addition, the inductive energy released during closing (demagnetism) is eliminated by a special damping snubber circuit, ensuring smooth operation of the on-off contactor. Magnetism and Demagnetism are done with automation-controlled control on the rectifier panel, On-Off and Reverse-Direct voltage application technique. In addition, due to the buffer charging feature of the rectifier, the battery group can be connected to the desired Ah capacity, ensuring healthy charging and at the same time ensuring uninterrupted safe operation of the iron lifting magnet in case of power outages. Iron removal rectifier (magnet rectifiers), special type input and output upon request.

The use of pole reversal control devices to control lifting magnets makes it possible to adjust the magnetic field very precisely. Thus, the USGs can be continuously adjusted in holding force and perform a demagnetizing cycle when switched off, which ensures that all parts are released and unwanted residual magnetism in the workpiece is minimized. USG pole reversal control units can be controlled via potential-free contacts with machine controls or pushbuttons in the crane operation and provide feedback on their switching status. As an option, we can also supply manual control units and signal lamp sets to match the pole reversal control units.

The electropermanent load lifting magnets from the EMPH series are suitable for the lifting and transportation of individual slabs and unprocessed blocks. These magnets are used to handle loads with a large air gap or with scaled surface. Only a 400V rated current must be provided to use these devices and they are then immediately ready for use. Through short electrical impulses within seconds, the EPMH from ASSFALG are automatically switched on or manually with the push of a button. No electricity flows during load transport and nevertheless, the workpiece is as securely clamped as with a permanent load lifting magnet. Through the impulse current control, the EPMH load lifting magnets do not use much energy. The effectiveness and efficiency can be seen on the one hand in the reduction of operating costs and on the other hand in a saving of time.

The SB950-SF is equipped with the highest safety technology. The electropermanent battery lifting magnet SB950-SF is the top product from ASSFALG in the 950kg load range for flat material. 400kg can be lifted for round material. The SB950-SF has an installed sensor. It measures the magnetic force, compares it with the workpiece weight and shows on the display if the workpiece can be transported. Parameters such as surface property, material thickness and material are considered here. They combine the advantages of permanent load lifting magnets with those from electro load lifting magnets. Through electrical impulses within seconds, the electropermanent battery lifting magnet SB950-SF from ASSFALG can be automatically or manually switched with the push of a button. Even though no electricity is present during the load transportation, the workpiece is clamped as securely as it would be with permanent load lifting magnets.
