The digital ammeter
Purpose
The digital ammeter A-05 is intended for measurement of size of current in current chains with a frequency of 50 Hz. The ammeter is equipped with the switch allowing to use it with various transformers of current with current of a secondary winding – 5 A.
We make 2 models of ammeters:
А-05 - for alternating current;
А-05 DC - for a direct current.

Design of system
The ampermeter of digital A-05 is executed in the case for installation on a DIN lath.
On the forward panel of the block there is a digital indicator and the handle of the SETTING of PRIMARY CURRENT switch.
Power-supply circuits and measurements are galvanic divided.
In the lower part of the block there are terminal blocks for connection of the block to networks and to a secondary winding of the transformer of current. Power supply of the relay it is carried out directly from a controlled network.
Warranty period – 2 years.
