NOTES
150 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 ensure input stability at low line. See sections entitled System Instability Considerations and
Input Voltage Range.
2Measured at the remote sense points.
3Unit regulates output voltage to zero load.
4CLOAD = 0.
5Output is fully loaded into a constant resistive load.
6Refer to Thermal Characteristics section for more information.
7Unit has internal pull-down; refer to section entitled Pin 7 (SYNC).
Specifications subject to change without notice.
