Blue Sea Systems AC Analog Voltmeter 0-150V

The Blue Sea Systems AC Analog Voltmeter gives a classic dial display of AC voltage from 0 to 150V, connecting with just two wires directly to the AC hot and neutral being monitored — the meter senses and powers itself entirely from that same connection.

Key features

• 0-150V AC display range, dial marked in 5V increments
• Simple 2-wire connection to AC hot and neutral
• Meter senses and powers from the same connection — no separate power wiring needed
• Backlit face for visibility in low light

This is a straightforward way to confirm shore power or generator voltage is within a safe range before switching AC loads on, or to catch a developing problem with an AC source before it damages sensitive electronics downstream. Because it reads directly off the hot and neutral conductors, installation is as simple as landing two wires — no separate current transformer or shunt required, unlike an ammeter, which requires a current transformer or shunt to make its measurement.

Pair it with the matching AC Analog Ammeter (PN 8258) for a complete analog AC monitoring pair at the same panel location, giving both voltage and current at a glance. The 5V dial increments give reasonably fine resolution for spotting voltage sag under load or confirming shore power is delivering a proper 120V before plugging in.

Because it needs no separate power supply and installs with just two connections, this voltmeter is a quick, straightforward addition to an existing panel that currently has no AC voltage indication at all.
