Serye ng VTG Tatlong Phase na Solid State Relays

Ang serye ng VTG three-phase solid state relay (SSR) ay isang contactless switching device na itinayo khusus para sa industrial grade three-phase load control. Batay sa semiconductor technology, ito ay nagko-control ng mataas na current on/off sa pamamagitan ng microelectronic signals, ganap na nagsasalitunin sa mga tradisyonal na mechanical relays. Ang seryeng ito ay naglalaman ng dalawang working modes: zero crossing conduction at random conduction, na sumusuporta sa 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 mekanikal na contact structure, anti vibration, explosion-proof at corrosion-resistant, na may buhay na maaaring umabot sa ilang dosenang beses ng mga tradisyonal na relays.
2. Mataas na resistance sa interference
2500V electrical isolation para sa input/output terminals, kompatibleng sa TTL/DTL/HTL logic levels, matatag na resistance sa electromagnetic interference.
3. Dynamic response
High dv/dt tolerance (>1000V/μ s), precise control ng inductive load start stop, at pagsuppresyon ng voltage spikes.
4. Intelligent visualization management
LED input status indication, real-time monitoring ng control signals, pagpapataas ng efficiency ng fault diagnosis.
5. Malawak na compatibility control
Sumusuporta sa DC 3-32V o AC 90-280V control voltage, kompatibleng sa iba't ibang signal sources tulad ng PLC at temperature controller.
