The Power-Tronics ABF10 Automatic 
Battery Flash Module is a convenient and 
compact optional automated flashing 
module for all Power-Tronics voltage 
regulating products and is compatible with 
many other manufacturers’ voltage 
regulators.  The ABF10 offers an easy 
method to add a fully automatic 
aftermarket battery flash unit to any 
generator. 
 
The ABF10 is designed specifically for 
automated battery flashing of a generator’s 
control field.  A reduced wire count and 
generic installation make the ABF10 
suitable for use on a wide range of 
applications.  Automating the battery field 
flash improves reliability and greatly 
improves safety for the operator. 
 
Like the rest of our products, the ABF10 
Automatic Battery Flash Module is 
designed and manufactured with heavy 
duty components to withstand the harshest 
environmental conditions and provide 
extreme reliability.  Onboard fusing and an 
encapsulated design mean the ABF10 will 
stand up to extreme operating conditions. 
 
Indicator lights help the operator know the 
status of the flashing module and a voltage 
operated design helps guarantee reliable 
voltage buildup and a safe flashing 
process.
