For MACO power supplies, the battery backup is connected online throughout the transfer of the load. If a power failure occurs in the network during the course of magnetization, the battery takes over powering the magnet without any interruption.
Any variation from the nominal voltage in the event of a loss of one phase or drop in system voltage is closely monitored. These statuses are immediately signaled both visually and acoustically.
Circuits and backup functions are always tested when magnetization is switched on and in the event of a failure, the magnetization process is terminated. The ground connection for the magnet is continuously monitored as well, it is indicated if it occurs and further magnetization is prevented.
To prevent the magnet from overheating, the electrical current and duration of magnetization are measured and monitored at the same time.
If the customer desires, a MACO power supplies can be delivered in the 3rd or 4th safety category ( EN ISO 13849-1). We also deliver redundant power supplies for use in ports or other highly exposed areas.

For cranes that use the MACOperm power supplies for electro permanent magnets, safety is ensured primarily by the physical principle of these magnets, which retain their magnetization after being magnetized until they are demagnetized.

A load test is used to ensure there is sufficient retaining force for the transfer of material and involves using a decreased electromagnetic force to grab the material for transfer, followed by increasing the attraction force to maximum before the crane gets underway.

In accordance with customer requirements, the power supply can be delivered Ex “p” according to EN/IEC 60079-0, 60079-2.
