NOTES
1Military subgroups apply only to military qualified devices.
250 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.
3Measured at the remote sense points.
4Output characteristics tested with balanced loads on each output; however, unit operates with unbalanced loads up to 90%/10% split.
5CLOAD = 0.
6Refer to section entitled Thermal Characteristics for more information.
7Unit has internal pull-down; refer to section entitled Pin 7 (SYNC).
Specifications subject to change without notice.
