Product catalog summary
Overview: The T154 is an electronic microcontroller-based device designed for temperature control of medium voltage (MV) dry type and cast resin transformers. It features a dual display and an advanced microcontroller for enhanced operational capacity and data management. The unit is known for its high protection against electromagnetic interference and user-friendly interface, making it a standard in its application.
Specifications:
  • Inputs: 4 RTD PT100 inputs (3 for phase transformers, 1 optional for core or ambient temperature), with removable rear terminals and protection against electromagnetic interference. Cable compensation up to 500 meters.
  • Outputs: 4 dry contact relay outputs for ALARM, TRIP, FAULT, and FAN control. Output contact capacity is 10A-250 Vac.
  • Power Supply: Universal input from 24 to 240 Vac-dc, with reversible polarities.
  • Environmental Resistance: Option for tropicalization to withstand high temperature and humidity conditions.
Performance and Testing:
  • Complies with CE standards and provides protection against electromagnetic noise (CEI-EN61000-4-4).
  • Dielectric strength of 1500 Vac for 1 minute between relays and sensors.
  • Operating temperature range from -20°C to +60°C, with 90% non-condensing humidity.
  • Self-extinguishing housing and IP65 polycarbonate front film.
Data Management:
  • Features two 13 mm displays for temperature, messages, and channel display.
  • Includes LEDs for alarm and FAN status indication.
  • Temperature monitoring from 0°C to 240°C with multiple ALARM thresholds.
  • Diagnostic features for sensors and data storage, with programming access via front keyboard.
Dimensions: 100 x 100 mm with a depth of 131 mm, panel cut-out of 92 x 92 mm.
Additional Versions:
  • T154-V with Voting function (cod.1CN0182).
  • T154 EN50121-5 2017 (cod.1CN0208).
  • T154 WS with power supply 85-260 Vac-dc (cod. 1CN0247).

T154-1

microcontrollore per il controllo della temperatura di trasformatori MT incapsulati in resina e a secco. Costruita con il layout e i plus della Nuova Piattaforma (doppio display, microcontrollore piu performante con aumento della capacita operativa e di gestione dei dati), la centralina garantisce elevatissimi livelli di protezione ai disturbi elettromagnetici ed una semplicita di uso che ne hanno fatto lo standard per questa applicazione. La T154 mantiene i canonici 4 ingressi PT100 (tre canali per le fasi piu un quarto opzionale per il nucleo o per la temperatura ambiente) e 4 uscite con rele a contatto pulito, pre-allarme e sgancio (ALARM e TRIP), segnalazione anomalia di funzionamento (FAULT) e azionamento sistema di ventilazione (FAN). A richiesta la centralina puo essere certificata per il mercato americano e canadese, nonche per applicazioni navali. Tutte le nostre centraline possono essere fornite tropicalizzate, ovvero resistenti a situazioni climatiche difficili, in particolare caratterizzate da temperatura e tasso di umidita elevati (quali si trovano, appunto, nei climi tropicali). Electronic microcontroller based unit for the temperature control of MV dry type and cast resin transformers. Developped with layout and advantages of the New technology Platform (dual display, new microcontroller with increased operational capacity and data management), the unit ensures high levels of protection to electromagnetic interferences and ease of use which have made it the standard for this application. The T154 maintains the standard 4 PT100 inputs (3 phase transformer and a fourth option for the core or the ambient temperature), and 4 dry contact relay outputs, ALARM and TRIP, FAULT signal operation and start ventilation system (FAN). On request, the unit is available with c(Jj^DS certification for Canadian and American market, as well as for marine All our units can be supplied with a special coating on the electronic cards, resistant to difficult weather conditions, particularly characterized by high temperature and humidity (which are in tropical climates). UNIVERSAL POWER SUPPLY With input from 24 to 240 Vac-dc. OTHER VERSIONS - T154-V with Voting function (cod.1CN0182). - T154 WS (cod. 1CN0247) power supply 85-260 Vac-dc.
