Based on the company’s MM9200 300V 10A single-pole single-throw switch, the demonstration is of technology behind a 1,000V and 10,000A circuit breaker being designed for the US Navy.
According to the company, the MM9200 is for cold switching, has a 10mΩ contact resistance and needs a 90V control at 9nA to hold it closed. Switching is in 30μs. A 10A relay based on this measures 30 x 25 x 4mm.
In the PCIM proof-of-concept, arrays of MM9200 switches are configured into 1,000V 125A modules, then four modules are combined into hot-swapable sub-system, and multiple instances of the sub-systems are paralleled to meet the current requirement.
The company claims size and power wastage advantages over conventional electromechanical relays and solid-state relays.
“In addition to defense applications, we are engaging customers across power control and protection applications,” said Menlo CEO Russ Garcia. “We anticipate adoption across factory automation, data centers, smart grid infrastructures, EV charging infrastructure and building management.”
