Voltage converters
Voltage converters for universal use
The perfect link between vehicle battery and appliance
They combine what was never intended to be combined. If the 12-volt navigation system is powered by the
24-volt on-board battery and the 24-volt fleet management computer easily copes with a 12-volt supply,
there’s bound to be a PerfectPower voltage converter somewhere along the line.
In these units, the input voltage is electrically isolated
from the output voltage to compensate for under- and
over-voltage on the input side.
Due to this feature, the voltage converters meet the high-
est demands for voltage stability and operating safety.
This makes them ideal for sensitive appliances or use in
safety-conscious areas, e.g. hazardous goods transport.
PerfectPower voltage converters have an electronically
regulated output voltage, to which they owe their extra
function as a high-quality IU charger. Moreover, several
converters can be used in parallel.
