Digital indicator of current intensity three-phase DMA-3 true RMS DMA-3RMS

The DMA-3 current intensity indicator is used for continuous reading of the load values of electric circuits of a three-phase network. DMA indicators are designed to work with current transformers with a rated secondary current of 5A. Current transformer current range: 25-1000/5A. The primary current value of the transformer determines the maximum measured current and the actual current value indicated on the indicator. DMA-3 20A is designed for direct measurement (without the use of transformers) in the range of 0-20A.
