The Maretron M000630 Current Transducer is a precision analog sensor designed to work exclusively with the Maretron ACM100 Alternating Current Monitor. It measures the AC current flowing through a conductor and sends that data to the ACM100, which then broadcasts it over the NMEA 2000 network.

Core Technology & Performance

• Non-Invasive Measurement: The transducer uses a toroidal induction coil that fits around a single AC conductor (Phase A or Phase B), allowing it to measure current without breaking the circuit.

• Wide Operating Range: Rated for currents up to 100 Amps AC, it is suitable for monitoring shore power inlets, larger generators, or heavy-duty onboard appliances.

• High Precision: Offers an accuracy of ± 1% @ 50-60Hz, ensuring your NMEA 2000 displays reflect true real-time power consumption.

• Durable Construction: The sensor is fully encapsulated and designed to operate in extreme engine room temperatures ranging from -40°C to 80°C.

Technical Specifications

In The Box

• (1) Maretron 100A AC Current Transducer

• (1) Integrated 1-meter Signal Cable (Bare Wire)

• Installation Data Sheet

Installation Tip: The transducer has black and white wires that must be connected to the ACM100 terminal block. Connect the black wire to pin 7 (IA+) and the white wire to pin 8 (IA-). Ensure the AC source is de-energized before placing the transducer around the conductor.

If you are monitoring a high-capacity commercial system, I can find the Maretron 400 Amp Transducer (M000612) or suggest the ACM100-01 Monitor Unit if you are building a new system. Do you want me to do that?
