Resolution
The control power for the CM4000 series Circuit Monitors is rated for a voltage range of 90-305V ac or 100-300V dc. It was our standard practice to publish these ratings. Recently a change was implemented to mark the circuit monitors with the nominal voltage ranges instead of the maximum range. As a result the meters now show a control power voltage range of 100-277 V ac or 125-250 V dc.
