MAXQ™ DC Solid State Contactor

(Fast Model)


"One of the powerful DC solid state contactors yet!"



    Mechanical DC contactors have a limited performance and lifespan. Now there is finally a solution. MAXQ™ high current DC output solid state relay do not wear, do not arc, can switch 100x faster and last more than 100x longer.

MAXQ™ Fast Model:

  • Maximum semiconductor performance

  • On/off within μs

  • No minimum operating voltage

  • 3-32VDC control

  • Switch up to 6000V, 3500A, 10KHz

  • Normally open or normally closed

  • Optional auxiliary contact

  • MTBF 3million hours, or 50 to 300million operations

  • Made in Canada


*Fast Model requires 12-24VDC power supply. For Standard Model (<20Hz) without this requirement, click here.
