REV C Page 10 of 17Dual output modules: <1% pk-pk.DYNAMIC LOAD TRANSIENT RESPONSEA 25% step load change will result in an output deviation (overshoot or undershoot) of lessthan 3% of nominal output voltage (150mV for <5V outputs, 400mV for the module). Output voltage will recover to within 1% of set value within 300s (500us for theDYNAMIC CROSS REGULATIONThe effect of dynamic cross regulation on any fully loaded auxiliary channel for a load stepchange of 25% from a 75% base value on the highest rated channel, at a slew rate not toexceed 1A/us, shall be less than 0.1% for single output modules and less than 3% for dualoutput modules. The summation of the individual module powers must not exceed the totalrated power of the UF1500. This measurement is to be performed with all other channelsloaded to 50% of rated load.TEMPERATURE COEFFICIENTThe output voltage will change less than .02% per oC over the ambient temperature range of0-50 oC. (After 30 minute warm-up).NO LOAD OPERATIONOperation at no load will not cause damage to the UltraFlex supply, however the outputvoltages may be outside the regulation band. A 1 Ampere preload is required on the highestrated output for a dual output module.OVER TEMPERATURE SHUTDOWNThe power supply is self-protected against over-temperature conditions. A thermal shutdownrequires re-cycling of the input voltage to restore output. The fan will continue to operateduring thermal shutdown.OPERATING ENVIRONMENTThe power supply is designed to meet the performance parameters defined above whenoperated within the following conditions:Temperature: 0 to 50 o C; -20 oC Start-Up, 30 Minutes to performwithin specifications.Humidity: 10% - 90% Non-condensingAltitude: 0 – 10,000 ft. OperatingThe power supply will not be damaged during transit and storage when subjected to thefollowing conditions:Temperature: -40 oC to +85 oCHumidity: 90% Non-condensingAltitude: 40,000 ft.
