ECA Group designs and manufactures AC/DC power converters for maritime applications. These reliable AC/DC 28v,12KW-115v,400Hz,40KVA converters can supply helicopter ignition systems on frigates. They convert 400VAC/60Hz, into 28VDC with a 400A output current. Cooling is by natural air convection. For utmost safety, output voltage and currents are monitored, and our converters provide electrical protection against input voltage spikes, short-circuits, overloads, power surges, brownouts and over-voltages.
