NT935 WS

Free from any wiring thanks to the certified 2.4 GHz WiFi interface, the NEW WS LINE makes installation even easier and faster. It can be connected to a pre-existing WiFi network (Host mode) and controlled remotely.

In the Access Point mode, it is also possible to dialogue with the monitoring unit within the WiFi range.

The 2.4 GHz signal strength is guaranteed by the presence of an external antenna which, in case of need, can be disconnected and repositioned to obtain a greater coverage.

Equipped with a simple graphical interface for displaying the information detected on the state of the transformer, it offers the possibility to intervene for programming and configuring the system.

The alarms are saved internally to the WS unit, through a datalogger function – WebServer – which makes the new WS line a sort of transformer Black Box.

The temperature trend is displayed by a selectable time windows graph, allowing predictive evaluations on the health status of the transformer, without having to install dedicated Apps or Software, but only thanks to the use of an Internet Browser.

The NT935 WS maintains the traditional 4 Pt100 inputs (windings + environment) and 5 relays ALARM, TRIP, FAN1 – FAN 2 and FAULT; it is dedicated, mainly but not exclusively, to the control of MV / LV transformers.

In addition to the standard certification, the NT935 WS is RED certified for the limitations of Radiofrequency noises, as required by current regulations.

On request, the unit is available with  certification for Canadian and American market.

All our units can also 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).
