Shore Power

Switch over units for several sources

Automatic switch over units are useful for comfortable switching over between shore-/ onboard-generator- and/or inverters. The new switch over units of the series LAU are measuring the input voltage of each source and connect them to the on-board system if the voltage is high enough for the intended need (voltage & timewindow adjustable). Because of this, an AC-generator isn`t connected before it is ramped up correctly and reached it`s voltage. The switch over units LAU are prepared for the connection to the philippi PBUS. In connection with the system monitor PSM such factors as switch over delay time and voltage threshold are adjustable to each power supply source. An additional power output circuit enables an exclusion for example of the charger during the use of an inverter; because then the batteries would be discharged unintentionally without use.

The switch over units can be used either as only switch over units for existing AC-systems or with integrated RCBO leakage protector. In addition there is space to integrate optional components such as an AC-transducer ACW or double pole circuit breakers MCB. While integrating an AC-transducer ACW the performance data of the AC-system could be displayed on the system monitor PSM. Optional the shore power units can be designed and built to your special needs regarding the amount and power output of the sources and consumers. The units shown are a small example of the varieties possible. Please don`t hesitate to ask for more information.
   

Switch over of several power sources


If a generator and/or inverter will be connected additionally to the shore power connection into existing inverter board system it is necessary to use switch over units to disconnect all power sources. The switch over unit with delayed switching among different sources. So it is prevented the risk of a short circuit, caused by phase-shift in the sources and inductive load currents. When retrofitting a switch over unit it must ensure that the outputs are connected to a RCB leakage protector.
