    摘要: A system for measuring soft starter current includes a current monitoring system including a controller and a current transfer device that includes a first thyristor and a first conductor coupled to the first thyristor and configured to convey a first current flowing through the first thyristor, wherein the first current includes current flowing through the first thyristor when the first thyristor is in an off state. The system also includes a first current sensor configured to sense the first current and a first current measurement circuit coupled to the first current sensor and coupleable to the controller and configured to output a first output value to the controller representative of the first current flowing through the first thyristor. The controller is configured to determine an impending inoperability of the first thyristor based on the first current and alert a user if the first current indicates the impending inoperability.

    摘要: A 2-terminal solid state electrical switch is provided which can be connected in series with a load device in a the same manner as a conventional mechanical-contact switch, does not leak current during an "OFF" state, and operates from a dynamic pulse run mode during an "ON" state. The two-terminal solid state electrical switch of the present invention requires neither a power supply to operate, nor any mechanical movement and contact points. Consequently, no spark, arc or any mechanical noise is created in the solid state electrical switch's operation, nor does it corrode, thus allowing it to be used in a hostile environment. The solid state switch of the present invention can be put to uses not practical for conventional mechanical-contact switches, such as to control multi-appliances, as static circuit breakers, contactors and relays for fire-proof, explosion-proof, water-proof, anti-chemical, anti-corrosion, humidity resistant, dust resistant, anti-vibrations and heavy duty frequently operations. Further, a unique initialization circuit in the solid switch of the present invention resets the switch intelligently to a suitable operating mode after a power interruption, thus avoiding accidents that may endanger property and lives. The present invention also provides a highly isolated multi-point random remote control switch/relay suitable for wide industrial and other applications.
