MACOdrive power supplies include an off-line backup battery. 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 tested periodically when magnetization is switched on and in the event of a failure, the magnetization process is terminated.
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 MACOdrive 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.
