Mach-1™ DC Output Solid State Contactors (for applications up to 1500V, 500A)

Following the success of our MAXQ™ solid state contactors (SSC) for high current switching, we are now introducing the latest Mach-1™ DC-Output SSC for switching medium current in the 100A to 500A DC range.

Mach-1™ SSC shares the same semiconductor controls technology that has assisted many of our clients, including NASA, GM, Rockwell, and E-one Moli. It does not wear, does not arc, and is the only switch you will need for decades to come!

Two available models:
1)Mach-1™ Standard Model operates just as a mechanical DC contactor.
2)Mach-1™ Advamced Model for PWM up to 10kHz, or for ON/OFF in <20μS.


Switch up to 500A & 1500VDC


Lasts 100's times longer than mechanical switch


Advanced model switches up to 10kHz


Models support CMOS/TTL/PLC signals

Frequently Asked Questions

Can your solid state contactors reliably switch high DC current?

Absolutely! We have 100's of high power solid state contactors in service across many industries, including automotive, automation, and scientific research,
Some applications operated at well over 1000 Amps and 1000 Volts DC..

How do I select the right voltage/current ratings?

Different manufacturers may rate their devices differently; some with ratings based on room temperature performances, some with ratings that cannot be realized by the product design.
We rate our devices based on a very practical approach. For example, if the specified rating is 400A of resistive current, you can be confident that the device can switch and hold 400 amps continuously in a typical resistive application.

You may directly request our recommendations here, by completing a technical survey.
Alternatively, you may contact us directly here to assist you with rating considerations.

How do I order?

Orders can be placed directly online here, or by sending us a RFQ via email on the product page.

Is this part UL certified?

We use UL certified parts only, from terminals, epoxy, to the semiconductor itself.
If external UL marking is required, we may be able to accommodate this via field certification or other means. Please contact us for more details.
