The Blue Sea Systems 1837 M2 AC Voltmeter reads 50 to 250 volts at 1 volt resolution on a large OLED display, handling two independent circuits.
Two circuits on one meter is what makes this useful on a boat with both shore power and a generator. Both sources can be watched from one face instead of guessing which is feeding the panel, or it handles a single double-phase circuit instead.
Low voltage is the alarm that saves equipment. A dock pedestal sagging under load will cook motors and compressors long before anything trips. Nothing in a conventional panel catches that, since the current stays within limits while the voltage drops. High voltage alarms are included too.
It does one job rather than combining functions, which keeps the display large and the reading unambiguous. The display auto-dims, the 92 dB alarm adjusts easily and an isolated MOSFET relay is fitted. Face 55 by 28 mm, running on 7 to 70V DC at 0.3 to 1.0 watt. Explore more marine electrical meters.
