NOTES
1
440 V dc upper limit rated for transient condition of up to 50 ms. 160 V dc lower limit rated for continuous operation during emergency condition. Steady state and
abnormal input voltage range require source impedance sufficient to insure input stability at low line. See sections entitled System Instability Considerations and Input
Voltage Range.
