ESR10 Micro ISO Solid-State Relay

E-T-A’s ESR10 Micro ISO solid-state relays were specifically designed for use in 12 V and 24 V vehicle on-board electrical systems. The solid-state technology of the ESR10 offers silent in-vehicle switching and also makes the relay resistant to vibration and dust commonly found in vehicle applications. Its high frequency electronic switching makes it compatible with pulse width modulation (PWM) and it requires a fraction of the control power required by standard electro-mechanical relays. The ESR10 Micro ISO solid-state relays are suitable for switching resistive, inductive, and capacitive or lamp loads. While the ESR10 is not a direct replacement of standard Micro ISO electro-mechanical relays commonly used in vehicles today, it can replace these devices when electro-mechanical relays are not a viable option. For example, when applications require high frequency or silent switching, there are low power drive signals from the APC or controller, or applications using pulse width modulation (PWM).
