Digital current value indicator, single-phase DMA-1, semi-intermediate measurement 30/5A

Digital current value indicator, single-phase DMA-1, semi-intermediate measurement 30/5A

Operation:

The measuring circuit is separated from the indicator power circuit.

Designs:

DMA indicators are designed to work with current transformers with a rated secondary current of 5A. Current range of current transformers: 25÷1000/5 A. The primary value of the current transformer determines the maximum measured current and the actual current value indicated on the indicator.
DMA-1 20 A is designed for direct measurement (without using transformers) in the range of 0÷20 A.
