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 DC ammeter displays 0–199 amps from a 0–100 mVDC shunt input. It requires an external 200 A/100 mV current shunt, and Common Ground Marine SKU CSH-LB-200-100 provides the matching rating; the full circuit current does not pass through the meter. The display updates at three readings per second with accuracy of ±(0.05% of full scale + 1 count), making it suitable for marine DC and generator panels that need clear current monitoring. Also used in select Hatteras and Cabo replacement meter applications. No OEM endorsement or affiliation is implied.
