Inrush Surge Current Internally limited by thermistor. Vin = 230 VAC, one cycle, 25°C. 35 APK Power Factor Per EN61000-3-2. 0.95 W/VA Operating Frequency Switching frequency of main output transformer. 129 Switching frequency of secondary transformer. 70 kHz Switching frequency of Power Factor Correction circuit. 60 Output Specifications PARAMETER CONDITIONS/DESCRIPTION MIN NOM MAX UNITS Efficiency Full rated load, 110 VAC. Varies with distribution of loads among outputs. 65 75 % Minimum Load, V1 Minimum load required to maintain regulation on V2 Single output models 0 All other models 4 Amps Minimum Load, V3 Minimum load required to maintain regulation on V4 Single output models N/A PFC250-4000 1.25 Amps All other models 0.6 Ripple and Noise Full load, 20 MHz bandwidth. See Model Selections Output Power 300 LFM forced-air cooling. 250 Watts Overshoot /Undershoot Output voltage overshoot/undershoot at turn-on. 0 % Regulation Varies by output. Total regulation includes: line changes over the specified See Model Selections input range, changes in load starting at 20% load and changing to 100% load. Transient Response Recovery time to within 1% of initial set point due to a 25% step load from any 500 s load setting from minimum to maximum load. Turn-on Delay Time required for initial output voltage stabilization. 2 Sec Turn-on Rise Time Time required for output voltage to rise from 10% to 90%. 20 ms Interface Signals and Internal Protection PARAMETER CONDITIONS/DESCRIPTION MIN NOM MAX UNITS Overvoltage Protection Latch style overvoltage protection. Available on all 3.3V output, V1 4.1 4.65 single output models and V1, V2, and V3 on all 3.3V output, V2 4.2 4.2 multiple-output models. 5V output, V1, V2 6.0 6.4 12V output, V1, V2 14.0 16.0 V 15V output, V1 18.3 19.8 24V output, V1 27.0 30.7 48V output, V1 60.0 70.0 Overload Protection Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition. Overtemperature Protection System shutdown due to excessive internal temperature, automatic reset. Output Good TTL compatible signal. Signal is high when V1 output is 3.3V 3.16 V within 5% of nominal. Signal shall remain low for 20 5V 4.75 milliseconds following loss of Output Good. Input Power TTL compatible logic signal. Time before regulation dropout due to loss of input 5 ms Fail Warning power. May be used as independent PSOK signal in redundant applications. Current Share Accuracy of shared current with up to 6 parallel units. Single-wire current share 10 % on V1 and V2 with return via vegative (-) Sense return. Minimum current share load is 6A or 50W, whichever is smaller. Remote Sense Available on V1 and V2. Total voltage compensation for cable losses with 250 mV respect to the main output. Inhibit Output voltage is inhibited by application of external high (5V) signal. Standby Power Available with fan option versions only (+5VDC). 100 mA |
