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 voltmeter measures 0–285 VAC directly, without an external current transformer or shunt. The range supports common marine shore-power and generator applications, including panels that need to monitor higher-voltage AC sources. The display updates at three readings per second with accuracy of ±(0.05% of full scale + 1 count), providing a clear view of source voltage during connection, transfer, and operation. Its documented operating range is −10 to 50 °C, with a compact 2.10 by 0.85 inch panel cutout. Install with suitable circuit protection for the measured voltage.
