Solid state relays / contactors

POWERSWITCH - Wear-free, noiseless switching

Solid state contactors and relays from DOLD are the first choice everywhere that high switching frequencies and cycles in the industry are needed. They conduct switching and control tasks especially efficiently in numerous applications in industrial and building technology. Their long service life due to wear-free switching is the reason for this. DOLD also has an innovative answer to the problem caused by switching with high load currents, the severe heating of solid state contactors and relays: the use of DCB processes (Direct Copper Bonding) optimises the heat dissipation in the power stage of the device and thus ensure the operational security of your system. Solid state conductors are also used in other applications such as heating, lighting, et cetera.
