The Elektroblock EBL 220-4 A and EBL 220-4 with OVP is the central power
supply unit for all 12 V consumers connected to the electrical system of the
motorhome or caravan. It is normally fitted inside a cabinet or a stowage
space and can be accessed from the front to change a fuse.
The electroblock EBL 220-4 with OVP is suitable for all cases of application
in which the danger of overvoltage is especially large. This can e. g. be
lightning strikes in the public mains, generator operation, bad electronic
installations or trips to foreign countries.
For this in the electroblock an overvoltage protection is fitted in internally
between the mains connection and the loading module.
