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....
