Regulation
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%.

Overload Protection
Overtemperature Protection
Output Good
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.
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).
