Electrical Characteristics Notes
1. Converter will undergo input over-voltage shutdown.
2. Derate output power for continuous operation per Figure 11.
3. High or low state of input voltage must persist for about 200s to be acted on by the shutdown circuitry.
4. Current limit inception is defined as the point where the output voltage has dropped to 90% of its nominal value.
5. Parameter not tested but guaranteed to the limit specified.
6. Load current transition time ≥ 10s.
7. Line voltage transition time ≥ 100s.
8. Input voltage rise time ≤ 250s.
9. Operating the converter at a synchronization frequency above the free running frequency will cause the converter’s efficiency to be slightly
reduced and it may also cause a slight reduction in the maximum output current/power available. For more information consult the factory.
10. After a disable or fault event, module is inhibited from restarting for 100ms. See Shut Down section of the Control Features description.
11. Only the ES and HB grade products are tested at three temperatures. The C grade products are tested at one temperature. Please refer to the
Construction and Environmental Stress Screening Options table for details.
12. These derating curves apply for the ES- and HB- grade products. The C- grade product has a maximum case temperature of 100C.
13. The regulation stage operates to control the positive output. The negative ouput displays the cross regulation.
14. All +Vout and -Vout voltage measurements are made with Kelvin probes on the ouput leads.
15. Input Over Voltage Shutdown test is run at no load, full load is beyond derating condition and could cause damage at 125C.
