Silent, Fast, Durable & Efficient ISO Micro Solid State Relay


Does the transportation application you are currently designing require silent, high-frequency electronic switching, durability and efficiency? If so, standard electro-mechanical relays are not the ideal solution. E-T-A’s ESR10 Solid State Relays are:
  • Silent: Solid state technology eliminates in-vehicle switching noise
  • Fast: High-frequency electronic switching (PWM compatible)
  • Durable: Wear-free design, with no mechanical parts, resistant to vibration and dust
  • Efficient: Low power consumption
