Customized TISP® Pairs Solid State Relay (LCAS) Protection
Features TISP4125x3BJ TISP4219x3BJ coordinated pairs protectors designed protect Solid State Relays. Solid State Relays used line card applications where conventional electro-mechanical relays suitable, also referred LCAS (Line Card Access Switches). LCAS have more precise protection needs than electro-mechanical relays, requiring reduced voltage limiting protect between switch terminals from terminals ground. These surface mount packaged devices designed used protector pair, protecting line side LCAS battery backed, ground backed balanced ringing configurations. These separate devices need have different protection voltages allow system ringing signal pass below protection level, while minimizing stress SLIC.
