Mach-1® DC Solid-State Contactor (SSC) switches up to 2kV, 500A and 10kHz. It has no moving parts; thus, have the advantage of being arc-free, noise-free and wear-free over electromechanical DC contactors or power relays.
Mach-1 SSCs are highly powerful and versatile platforms. Its patented design and construction maximizes reliability and ruggedness. In addition, each contactor utilizes the latest semiconductor technologies, including SicFET & GanFET.
Two SSC Models are available:
- The Standard Model (M1DS- Series) may directly retrofit electromechanical contactors for applications switching <20Hz.
- The advanced model (M1DA- Series) is capable of switching up to 10kHz, enabling new applications in areas of load testing, high speed current interruptions, and PWM power controls.
Features & Selection Guide
- General Purpose Switch, No Moving Parts
- Proven Heavy-Power Operations
- TTL/CMOS/Logic Control Compatibility
- Patented Design, Rugged Construction
- Isolated Input/Output/Case

- Solid state switches in general, should be used at no more than 75% of its maximum peak ratings.
- For mission-critical applications, increase above margins by 25% or more.
- The above table is a general guideline only. Selection requirements may increase/decrease depending on the exact load and operating conditions.

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).
