ShipPower4AC Features and key points The ShipPower4AC module drives and controls 4 AC circuits of a ShipHeart™ system. DIN rail-mounted, it can be connected in a matter of seconds and requires no configuration to be recognized by the ShipBase module to which it is connected. Its position on the bus distinguishes it from other modules, and the termination resistors are automatically adjusted according to this new configuration. Connected after the protection circuit-breakers, ShipPower4AC monitors and controls each of its 4 circuits completely independently. This allows an AC circuit to be controlled in exactly the same way as a DC circuit: one touch of a finger on the ShipBase screen and the heater is energized... But also to use a ShipPower4AC as an AC source selector: the voltage supplied by the shore power is too high? the generator output frequency is too low? the on-board AC input is automatically cut or switched to the appropriate source. Each circuit has a two-point plug-in input connector: neutral on the left and phase on the right, like on a circuit-breaker... A male connector of the same type is available for the corresponding output. Simply slide one of the conductors through the currentmeasuring toroid, and the circuit wiring is complete! As there is only one on-board earth, only one connection is required to the module, via a quick-acting terminal block. ShipPower4AC then monitors each circuit: voltage, current, apparent power, frequency, as well as the presence of a valid ground circuit or phase/neutral inversion. All this information is, of course, visible on the ShipBase screen, with curves showing its evolution over time. And like all the modules in a ShipHeart™ system, the ShiPpower4AC has been designed to ensure that your equipment can always be used. To this end, the input and output connectors have been chosen so that each circuit can be bypassed by connecting the input directly to the output. Simple and effective. Every ShipPower4AC comes with a 5-year warranty Last but not least, all connections are made on plug-in, polarized, lockable and spring-loaded connectors, ensuring rapid connection without the need for special tools and, above all, insensitive to vibration and sea air
