This is how the memory steel is activated
A certain activation energy is needed to activate and prestress the elongated SMA. This happens by resistive heating with a specially designed electric power supply. re-fer delivers these devices to the construction site. They can be easily operated by just one person. The power connection can be either a 125A/390V port, if available on site, or a transportable generator with the required performance.
