Hoyt HST-75 2.5-inch Analog AC Voltmeter, 150 VAC

Hoyt Meter’s HST-75 series uses a compact 2.5-inch rectangular analog format with a clear black knife-edge pointer for at-a-glance monitoring at the electrical panel. This AC voltmeter reads 0–150 VAC directly, so no current transformer or external shunt is required. Its range is well suited to common marine 120-volt systems, including shore-power and generator panels where operators need a simple visual check of incoming or generated voltage. The four-stud mounting pattern supports replacement and new-panel applications using the HST-75 footprint. Because this model connects to the measured voltage circuit, installation should include the appropriate circuit protection and follow the vessel’s electrical standards. Common Ground Marine also supplies select HST configurations with custom ranges and scales for specialized marine panel applications.
