ENDA EPA742-230 is a programmable industrial digital ammeter designed for AC, DC and True RMS current measurement in electrical panels and industrial machinery.

Its 72x72 mm panel format and 4-digit display provide clear current indication, while configuration is performed directly from the front keypad.

The EPA742 can be used with either a current transformer or shunt resistor, allowing the displayed scale to be adapted to different current measurement applications.

The programmable measurement range can extend up to 9999A, depending on the current transformer or shunt configuration.

Measurement modes include:

• AC;
• DC;
• True RMS.

Current transformer and shunt measurement

Standard measurement inputs include:

• -5...+5A current transformer input;
• -60...+60mV shunt input.

For AC and True RMS operation, the programmable display range extends up to 9999A.
