Description
The Master Volt (Mastervolt) AC Amps Meter – 0–40A is a precision alternating current (AC) ammeter designed to accurately monitor AC current draw in electrical systems up to 40 amps. This instrument is most commonly used in marine, RV, off-grid, and industrial power installations as part of a system monitoring panel to provide real-time current measurement on AC circuits.
Features
- Wide Current Range: Measures AC current from 0 to 40 A, suitable for most household and onboard AC circuits
- Accurate Analog/Digital Readout: Designed to deliver clear and dependable measurement of current draw
- Panel Mount Design: Fits standard panel cut-outs for seamless installation in instrument clusters or power panels
- Durable Build: Suitable for marine, mobile, and off-grid applications where robustness is necessary
- Compatible with Mastervolt Monitoring Systems: Can be integrated into broader monitoring frameworks such as CZone or MasterBus where needed
