what is a contactor do
How do DC Contactors Work? DC Contactors are comprised of a high current switch and a solenoid in a single enclosure. The switch provides the desired function, to turn current flow on and off. Trombetta DC Contactors provide a robust and economical means to switch high currents in low voltage DC circuits.
How to reduce the size of a DC Power supply. The use of electronic DC contactors and control relays can reduce the size requirements of DC power supplies. The CRI7E external electronic interface is another way to reduce DC power requirements.
