Hydraulic pumps and other inductive loads are among the more challenging applications for solid-state contactors. However, when selected correctly,...

This year a team of scientists conducted research in Norway's Arctic circle in a race against time to understand the impact of climate change.The Arctic's harsh environment poses unique challenges to electrical equipment as it is not uncommon for temperatures to reach -40ºC (-40ºF) or even lower. We, at Nominal Controls, are proud to have supplied the solid-state contactors that operated the equipment used in these expeditions. We commit to maintaining the highest quality standards, ensuring our components can withstand the harshest Arctic conditions. Our collaboration with scientists doesn't end with just providing the parts; we continuously engage with them, gaining feedback to further innovate our designs.

         In 2016, what started as an engineer's passion for tackling industrial controls problems, became a mission to develop unique, effective, and efficient solutions that benefit entire industries, including the aerospace and space sectors.

          Fast forward to today, we're thrilled to celebrate our 7th year of delivering cutting-edge solutions to our customers. This year, we're taking innovation to the next level with the release of our new DC solid-state contactor(SSC) models, and features. Our team has been hard at work integrating new technologies and developing solutions that meet the needs of our customers.

     We are pleased to announce that we have established a co-op program with University of Waterloo for science and engineering students! University of Waterloo has a long-standing international reputation for its exceptional research accomplishments and engineering programs. We are thrilled to be partnering with them to offer this opportunity. This long-term collaboration will be aimed at accelerating our research and development efforts while providing local students with the chance to gain practical skills and experience. Most importantly, to inspire them to work with future technology such as energy, electric vehicles, scientific research, and more here in North America. 

To ensure that our products continues to offer the optimal performance and the highest industry standards for our customers, we have implemented the following enhancements as of Jan, 2023. Mach-1® Series DC Solid-State Contactors:

• Stability improvements relating to control signal processing for models with high speed PWM capability.
• New compatibility with latest Silicon Carbide semiconductor technology.

DRV- Series DC Solid-state Motor Reversers:

• Default interlock timer set to 200ms from 100ms to lessen stress during DC injection plugging operation.
• New DC reversers rated 100VDC and 200VDC, with rated current up to 200A, providing greater flexibility in selection.
• Overall stability improvements
• Older models of the solid-state DC motor reversing relays have been replaced by new enhanced models. The obsolete part numbers include: FR-D1080M, FR-D10200M, DRVS01-50A4, DRVS02-80A4. Some of these models may still be available for purchase. Contact us for More Details.

To all our existing customers, thank you for your trust and confidence in our products. We seek to continue delivering the best quality products with the latest technological advancements. To our prospective customers with system developments still underway. We look forward to working with you throughout prototyping and production next year.

This year's Honorable Mentions:

• Airbus SAS (most challenging)
• Tesla Gigafactory (most varieties)
• Clearflame Engine Technologies (most royal)
• Soncni Sistemi (furthermost customer)

We are pleased to announce that our Mach-1® Series of DC solid-state contactors recently received both patent and trademark certificates. The design of the Mach-1® DC Contactor was first conceptualized in 2019. Its goal was to achieve much higher power density, much higher robustness & reliability. The trademark was registered under Innovation, Science and Economic Development of Canada. Its patent has been registered both domestically and internationally.

DRVS-Series Minature DC reversing SSRs are designed with performance, and reliability in mind. For this purpose, we benchmark tested against industry's leading DP4R-Series. The setup involved both solid-state DC motor reversers operating a 50A load for approximately 30minutes under the same ambient temperature and cooling conditions. The final result revealed that DRVS-Series operated at 15°C cooler overall, while taking less than half the space.

DRVS-Series solid-state relays and contactors reverse the polarity of DC loads (i.e. motors, actuators, and cathodes/anodes) with an internal H-Bridge. Minature DRVS-Series model is housed in an industry-standard  "hockey puck" 1.8x2.3" enclosure. Despite its small form factor, it can traverse loads up to 200VDC and 80A. The latest miniature DRVS-Series has been redesigned from the ground up, featuring improvements in multiple aspects, including chipsets, constructions, & soft-start/stop technology.

To ensure safe and reliable applications when using any of our DC solid state relays and ccontactors, there are 8 important facts to be mindful of. Keep in mind different manufacturers may specify SSR’s ratings differently. For example, some manufacturers may specify current ratings based on transistors’ performance at 25°C. Other manufactures may specify ratings without any de-rating considerations; in both cases the rated performance cannot be practically achieved. MAXQ™/Mach1™ SSR specifications are based on a more realistic approach, which is when the device is operating continuously with a baseplate temperature near 100°C....
