About this product
The isolated HDLA-30 design uses a bright 0.56-inch, 3.5-digit red LED display and 12–24 VDC auxiliary power for easy reading at marine electrical panels. This digital AC ammeter displays 0–99.9 amps and is designed to work with the specified HYT-P-CT-1000-101-X 100 A, 1000:1 current transformer. The measured conductor passes through the CT rather than through the meter, providing the scaled input the display requires. With three readings per second and accuracy of ±(0.05% of full scale + 1 count), it provides a responsive view of AC load on generator, shore-power, or distribution-panel circuits. Operating range is −10 to 50 °C. Confirm CT orientation and conductor routing during installation for correct current indication.
