Mach-1™ DC solid-state contactors (SSC’s) are built on a compact, versatile, and rugged platform designed for switching medium to high DC power up to 3,000V, 500A and 10kHz. Compared to conventional electromechanical DC contactors or power relays, solid state contactors can hot switch at much higher power without arcing or wearing.
Mach-1 DC Contactors features a patent pending design that utilize the latest semiconductor technology including SicFET and GanFET. Two models are available:
- The Standard Model (M1DS- Series) may directly retrofit electromechanical contactors.
- The advanced model (M1DA- Series) is capable of switching ON/OFF within 10’s of µS this enabling new applications in areas of load testing, high speed current interruptions, and PWM power controls.

FAQ
For General FAQ, please visit: Solid State Contactor FAQ
The 'standard model' is controlled by just a set of DC signal wires, 1 for the positive, 1 for the negative. It is most commonly used in electromechanical contactor retrofit applications where existing control input wires can be used directly.
The 'advanced model', in addition to the DC signal wires, requires a 12-24VDC power supply in order to run a central processor. However, it offers significantly more capabilities than the 'standard model', such as supporting auxiliary contacts, responding to ON/OFF command within 10μs, and PWM at a frequency up to >10 kHz with TTL/CMOS/logic signal. (Ask us about switching 100kHz).
