4PWR & 4DYN

4PWR is a flexible and high performance power meter and it is designed to be matched with 4DYN, the EN4 dynamometer, in order to achieve a complete system for electric motors tests.

4PWR allows the direct measurement, without external sensors, of tensions up to 1000V and currents up to 100A.

The performances of the instrument allow testing from power consumption measurement to R&D applications.


The user-friendly software allows to control all the functions of the instrument.

Measurement data can be displayed on a single screen, with the detailed setting information of inputs, such as voltage range, current range, or wiring system.
