SAN ANTONIO, Texas -- At APEC 2018, Menlo Micro announced its new 200V/10A Digital-Micro-Switch (DMS) Smart Power Relay technology. This technology represents another pivotal milestone for Menlo’s Digital-Micro-Switch platform.
The new DMS Smart Power Relay technology opens the door to a wide array of vertical market segments. Until now, many industries have had to live with the tradeoffs of solid-state controls, including high-leakage currents, lack of air gap and complicated thermal management, or electromechanical solutions that are slow, bulky and expensive.
Demonstrating the scalability of the technology, Menlo has combined over 200 micromechanical high-voltage switches, with fully integrated protection and controls, into a Smart Power Relay evaluation board. The credit-card-sized board is capable of carrying 10A of DC current, without the need of a heat sink. This unprecedented level of current handling for a MEMS switching device is due to Menlo’s proprietary materials, designs and wafer-level processing techniques.
High-power, high-reliability RF switches manufactured by Menlo are already in applications such as medical instrumentation, test and measurement equipment, and reconfigurable software-defined radios. Typically, these switches are 3-terminal devices operating in the 25W to 50W range. For the Smart Power Relay, Menlo has created a fully isolated 4-terminal architecture, complete with advanced features such as over-current protection. Some of the advantages of the DMS Power Relay architecture include:
Menlo’s DMS Smart Power Relays are ideally suited to home and building automation, industrial automation and controls, robotics, electric vehicle and battery management, and avionics.
This week at APEC’s Industrial Applications session, Dr. Yan-Fei Liu, IEEE Fellow, and Menlo Micro will present a paper titled, “Design of a High Power MEMS Relay with Zero Voltage Switching and Isolated Power and Signal Transfer.” The presentation is taking place at 5:10 p.m. on Thursday, March 8 in Room 217D and describes the new smart power relay architecture proposed by Menlo.
Menlo is currently making its DMS Power Relay technology available for evaluation to key industry partners. For more information, please visit www.menlomicro.com.
