CONDITIONS/DESCRIPTION
Continuous input range.
AC Input.
Lowest AC input voltage that regulation is maintained with full rated loads.
After last AC line peak at 250 watts.
85 VAC at full rated load.
Non-user serviceable internally located AC input line fuse.
Internally limited by thermistor. Vin = 230 VAC, one cycle, 25°C.
Per EN61000-3-2.
Switching frequency of main output transformer.
Switching frequency of secondary transformer.
Switching frequency of Power Factor Correction circuit.
CONDITIONS/DESCRIPTION
Full rated load, 110 VAC. Varies with distribution of loads among outputs.
Minimum load required to maintain regulation on V2
Minimum load required to maintain regulation on V4
Full load, 20 MHz bandwidth.
300 LFM forced-air cooling.
Output voltage overshoot/undershoot at turn-on.
Varies by output. Total regulation includes: line changes over the specified
input range, changes in load starting at 20% load and changing to 100% load.
Recovery time to within 1% of initial set point due to a 25% step load from any
load setting from minimum to maximum load.
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90%.
CONDITIONS/DESCRIPTION
Latch style overvoltage protection. Available on all
single output models and V1, V2, and V3 on all
multiple-output models.
Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition.
System shutdown due to excessive internal temperature, automatic reset.
TTL compatible signal. Signal is high when V1 output is
within 5% of nominal. Signal shall remain low for 20
milliseconds following loss of Output Good.
TTL compatible logic signal. Time before regulation dropout due to loss of input
power. May be used as independent PSOK signal in redundant applications.
Accuracy of shared current with up to 6 parallel units. Single-wire current share
on V1 and V2 with return via vegative (-) Sense return. Minimum current share
load is 6A or 50W, whichever is smaller.
Available on V1 and V2. Total voltage compensation for cable losses with
respect to the main output.
Output voltage is inhibited by application of external high (5V) signal.
Available with fan option versions only (+5VDC).
