Three phase without neutral, MID certificated network analyzer with Display for amperometric transformers
The energy meter KET-PMT-215.N is self-powered at 400 VAC without neutral, suitable for energy measurement in industrial and civil environment, with integrated RS485 ModBUS communication.
In addition to energy, the device measures the main electrical parameters and makes them available on the communication integrated port.
The front joystick allows easy scrolling of values and menus.
The KET-PMT-215.N is built in accordance with EN 50470-3, the accuracy of the active energy is referred to IEC/EN 62053-21 class 1 while that of the reactive energy is related to IEC/EN 62053-23 Class 2.
The KET-PMT-215.N is MID certified and can be connected to the Master ModBUS wireless KET-RMB-211 or directly to the Gateway X-Monitor.
