Controllers
Eberspächer VAIREX supplies motor controllers/drivers for our regenerative compressors from the prototype stage through production.
Eberspächer VAIREX is finalizing the development of a low cost, 10-100 VDC BLDC motor controller specifically for 5-10kW fuel cell applications. This controller allows connection directly to the fuel cell voltage output bus simplifying your fuel cell system. Contact VAIREX and watch this webpage for information as details become available.
