AFM500X

Automatic Flash Module

Adds Automatic Flash or

Battery Flash to installations

with low residual or requiring

guaranteed buildup!

UIC200

Optical Interface Module

Allows the XR500D to be

controlled externally by virtually

any digital load-sharing controller,

VAR controller, genset controller,

or digital governor controller!

MP12/MP24

Motorized Potentiometer

Allows the XR500D to be

externally controlled by older

automated controllers using

pulsed signals or dry contacts

for control!

HVD1

High Voltage Disconnect

Module

Saves your generator and connected

equipment from runaway voltage

conditions! Disconnects power to the

voltage regulator instantly in the

event of high voltage!
