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 insure 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; tests performed at low continuous load and 200 W pulsed load.
4CLOAD = 1,000 µF. Output ripple/noise measured at converter output; may be smaller at external load capacitance. Unit is stable for C LOAD ranging from 500 µF
to 4,000 µF.
5Refer to section entitled “Pulse Output Power vs. Pulse Length” for more information.
6Unit has internal pull-down; refer to section entitled Pin 7 (SYNC).
Specifications subject to change without notice.
