Alfatronix DC/DC CONVERTERS
PowerVerters

 
 

The 24Vdc to 12Vdc applications are catered for by a sub group of products, the PowerVerter series. This series has been optimised for high volume applications such as on heavy goods vehicles, coaches, buses, construction, forestry and agricultural vehicles and commercial vessels, large yachts and all types of aircraft. Consequently they are manufactured at low cost and offer excellent value for money.

All the PowerSelecter products are CE marked and those suitable for road traffic vehicles are also e marked. They all meet the requirements of FCC Class B.

 
 
  • Secure isolation
  • Cool running
  • Rugged and compact
  • Tamper proof
  • Fast installation

 
 

 

Product Coding
The product code is developed as follows, take PV3i as an example:
PV - PowerVerter 24Vdc to 12Vdc converter.
3 - 3 amps continuous output (12 Vdc output at 3 amps).
i - Isolated between input and output (s indicates switchmode, non- isolated).

 
All PowerVerters convert 24Vdc to 12Vdc
