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 free of arc, wear, and noises over electromechanical DC contactors or power relays.
Mach-1™ SSC platforms are highly rugged and versatile. A patent-pending mechanically assembled package maximizes reliability. In addition, each contactor utilizes the latest semiconductor capabilities, including SicFET & GanFET, while enabling series/parallel/unidirectional/bidirectional configurations.
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

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).
