Frequently Asked Questions - DCA-11S ENTES
What is the supply voltage required for the ENTES DCA-11S ammeter?
The DCA-11S operates on a nominal supply voltage of 230 V AC (±10%), 50/60 Hz.
How do I connect the current transformer (CT) to the DCA-11S?
Connect the secondary leads of the CT to terminals S1 and S2 on the rear panel. Ensure the CT is rated for 5 A secondary and observe polarity.
What is the maximum current this ammeter can measure?
The direct input range is 0-5 A AC. For higher currents, use an external CT with appropriate ratio. The display will show the primary current when the CT ratio is set via internal DIP switches.
Can the DCA-11S measure DC current?
No, this model is designed for AC current measurement only. It uses True RMS conversion for accurate reading of distorted waveforms.
What is the accuracy of the DCA-11S?
The accuracy is ±0.5% of full scale (5 A), which corresponds to ±0.025 A under reference conditions.
What are the panel cut-out dimensions for mounting?
The required panel cut-out is 45 x 45 mm. The overall dimensions are 48 x 48 x 80 mm (W x H x D).
How do I reset the peak hold value?
Press and hold the front panel button for 3 seconds to clear the peak hold value. The display will show the current measurement.
Is the DCA-11S protected against overvoltage?
Yes, it is rated for CAT III 300 V (measurement category) and includes internal protective features against transient overvoltages.
What does the display show when the input exceeds 5 A?
If the input exceeds the rated range, the display will flash ‘OL’ (overload) to indicate an over-range condition. Reduce the current immediately.
How should I clean the ammeter?
Use a dry, soft cloth to clean the front panel. Do not use water, solvents, or abrasive cleaners as they may damage the display or casing.
