NOTES
1
50 V dc upper limit rated for transient condition of up to 50 ms. 16 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.
2
Measured at the remote sense points.
3
Unit regulates output voltage to zero load.
4
C
LOAD
= 0.
5
Output is fully loaded into a constant resistive load.
6
Refer to section entitled Thermal Characteristics for more information.
7
Unit has internal pull-down; refer to section entitled Pin 7 (SYNC).
