The XL product specifications below were certified and tested by UL through field testing and laboratory bench testing.  UL also makes unannounced site visits to audit the manufacturing of XL-Series products, assembly processes and quality control testing.

The kW and kWh reduction performance value ranges below are conservative UL specifications.  It’s been confirmed that XL System performance results are facility specific in terms of electrical conditions, inductive and capacitive loads, operational runtime, and length of time XL modules are saturated. 

In other words, some facility conditions produce better XL System performance results than other facility conditions.  Specifically, facilities with poorer electrical conditions, more inductive loads and longer hours of operation produce better energy cost savings and efficiency results than facilities with lesser facility conditions.
