The Oceanic Systems 3420 AC Monitor accurately measures the AC voltage, AC current and AC Frequency and reports them over the NMEA2000® network.
The unit can be used for Single Phase, Two Phase, Three Phase and Split Phase systems and is suitable for measuring AC sources such as shore power, generators and inverters. It can also measure the voltage and frequency on AC Bus Bar Systems.
The voltage sensing is by simple phase and neutral connections to the unit. Current sensing is done by a state of the art AC Current Transformer placed around the conductor with no need to break the connection.
The unit has inputs for up to three phase voltages and up to three phase current transformers. It is supplied with a single phase current transformer. Additional transformers will be required to measure Two Phase, Three Phase and Split Phase circuits.
The 3420 has a blue LED that flashed as the unit transmits data over the network with configuration done with a suitable Oceanic Systems Display Unit, our Monex PC Software or pre-configuration when ordering direct from Oceanic Systems. Up to 254 units can be present on a single network.
The connections to the sensors are made via a waterproof and corrosion resistant DT15-12PA Deutsch Connector which allows for a secure and reliable connection.
