Description:
DIH-143 is State of the Art Solid State Relay designed for 28V DC aircraft power applications where speed, efficiency,
current overload protection and immunity to transient voltages are critical.
DIH-143 is Normally Opened (N/O) relay capable of continuous current of 1.5A. DIH-143 contains current limiting
networks and thermally sensitive integrated circuits that disable the outputs, if the output MOSFET approaches an unsafe
operating temperature. Because the thermally sensitive integrated circuits have built-in hysteresis, the output MOSFET is
automatically restarted when a safe temperature is reached. This auto restart feature eliminates the need for system restart
signals. If the overload condition continues to exist, the cycle is repeated; If the overload condition is removed, the relay
returns to normal operation.
