The Vanner 24V to 12V DC to DC Converter is an efficient and highly reliable method of obtaining 12 volt DC power from a 24 volt DC electrical system.Normal Operation: Model VC-30 DC to DC Converter will provide up to 30 amps continuous output and maintain 13.5 volts output voltage across the full range of DC input voltage.
No output condition: DC input voltage must be above 18 volts for the unit to "turn ON" and must remain above 14 volts during operation.
Overload Condition: An overload condition exists when the 12 volt load exceeds the VC-30 output rating of 30 amps. The symptoms that indicate an overload condition exists are output voltage below 18VDC combined with 30 amps output current. The overload condition will not damage the DC to DC Converter. During theoverload, internal protection circuits reduce output voltage as needed to limit the output current to 30 amps.
Ignition VC-30: The ignition line must be between 8 volts and 36 volts for the converter to turn on. The converter will turn off if the ignition line is below 1.5 volts and the load current drops below 0.5 amps.
Ignition VC-30-NLC: The ignition line must be between 8 volts and 36 volts for the converter to turn on. The converter will turn off if the ignition line is below 1.5 volts, regardless of the load current.
