OS100-0101 – Over Voltage Sensor (Alternate to C593003-0101)

Solid-state over-voltage protection sensor designed for aircraft electrical power systems to monitor bus voltage levels and trigger protective action when predefined limits are exceeded. The unit continuously senses system voltage and provides a signal output to alert or command load shedding, relay disengagement, or system shutdown in order to protect sensitive avionics and electrical equipment from voltage spikes or regulator failures. It is commonly used as a direct replacement or functional equivalent to legacy part C593003-0101 in certified aircraft systems.

Application:
Aircraft DC electrical power distribution systems, avionics power protection circuits, generator/bus monitoring systems, and voltage regulation safety monitoring in 14V/28V aircraft electrical architectures

Function:
Monitors system voltage and activates a protective output signal when over-voltage conditions occur, helping prevent damage to avionics, batteries, and electrical loads by initiating isolation or shutdown actions
