NOMINAL CONTROLS Mach-1 DC Contactors provides a solid state switching capability of 100 to 400Adc range. Devices incorporate semiconductor technology in an industry-standard panel mount solid state relay package. Products can handle high current, high voltage, and high frequency applications operating at up to 400A nominal (1200A inrush), 1500Vdc and 10kHz. Devices enable new feasibility with retrofitting higher voltage electro-mechanical contactors. Devices deliver interrupting current in <20μs for down-line protection, as well as fine-tuning dc power with PWM up to 10kHz.
