AFM500X
Automatic Flashing Module
The Power-Tronics AFM500X Automatic
Flashing Module is a convenient and
compact optional build up module for all
Power-Tronics UVR and XR series
Universal Voltage Regulators. The
AFM500X offers an automatic flash or
battery flash mode on the same module for
added versatility.
The AFM500X is a unique, automatic
flashing module designed specifically for
generators with very low AC residual
voltage, brush-type generators, and for any
installation where guaranteed buildup is
required. Operation is completely automatic
and installation into a Power-Tronics
regulating system is quick and easy.
The two modes offered by the AFM500X are
automatic flashing and battery flashing.
Automatic flashing uses the existing residual
AC voltage of the generator as a flashing
source, while the battery flashing mode uses
an external battery for it's flashing source.
All inputs are fused to protect any connected
equipment!
Like the rest of our professional line of
products, the AFM500X is fully repairable!
None of the major electronic components
are encapsulated to facilitate prompt repair!
The entire unit is coated in a protective film
to insulate it from any contamination and
moisture that may be present.
The AFM500X Automatic Flashing Module is
compatible with all previous UVR and XR
series Universal Voltage Regulators as well
as select VR series voltage regulators. The
AFM500X is also a very simple upgrade for
installations using older Power-Tronics
BU120/240 or BU500 series buildup
modules!
