Vespa - Horn - Regulator -
Many instruments require a constant 12v current to operate correctly. Due to many models not being originally equipped with a suitable electrical system, including both battery and a voltage regulator, Koso have developed and produced this voltage regulator.
It can be used to power Koso instruments but can also be utilized as an AC/DC Converter for models without a battery or to power other instruments such as a sat nav or horn.
Input: 12-30 Volt AC/DC, Output 12-15 Volt supply with a maximum power output of 6 Watts
If connected as follows it can be used as a direct replacement to the original PX/PK AC/DC Voltage.
All connections are from the voltage regulator unit to the wiring loom.
