Ang serye ng VTG three-phase solid state relay (SSR) ay isang contactless switching device na idinisenyo nang espesyal para sa industriyal na grade na three-phase load control. Batay sa semiconductor technology, ito ay nagkontrol ng mataas na current on/off sa pamamagitan ng microelectronic signals, kumpleto ang pagsasalitunin ng tradisyunal na mekanikal na relays. Ang seryeng ito ay naglalaman ng dalawang working modes: zero crossing conduction at random conduction, suportado ang malawak na current range mula 3 × 25A hanggang 150A, angkop para sa 480V/530V AC systems, at nagbibigay ng mataas na stability control para sa mga load tulad ng three-phase motors at heating equipment.
Mga Advantages ng VTG series three-phase solid-state relay products:
1. Mahabang buhay at mataas na reliabilidad
Walang mechanical contact structure, anti vibration, explosion-proof at corrosion-resistant, may buhay na maaaring maabot ang napakaraming beses kumpara sa tradisyunal na relays.
2. Mataas na anti-interference performance
2500V electrical isolation para sa input/output terminals, compatible sa TTL/DTL/HTL logic levels, matibay ang resistensya laban sa electromagnetic interference.
3. Dynamic response
Mataas na dv/dt tolerance (>1000V/μ s), precise control ng inductive load start stop, at suppression ng voltage spikes.
4. Intelligent visualization management
LED input status indication, real-time monitoring ng control signals, pagpapahusay ng fault diagnosis efficiency.
5. Malawak na range compatibility control
Suportado ang DC 3-32V o AC 90-280V control voltage, compatible sa iba't ibang signal sources tulad ng PLC at temperature controller.
Application ng VTG series three-phase solid-state relay products:
1. Industrial automation system
Three phase motor start stop control (fan, pump, conveyor belt)
