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 frequency meter is intended for 50 or 60 Hz AC systems and accepts 120/240 VAC frequency input directly; no current transformer or shunt is required. The documented input span supports 40–90 Hz monitoring, allowing the display to show generator or shore-power frequency as the source stabilizes and operates. It updates at three readings per second with accuracy of ±(0.05% of full scale + 1 count). The meter is well suited to marine generator and shore-power panels where frequency is a key indicator of source quality. Operating range is −10 to 50 °C.
