1. Peak current lasting <30 seconds with a maximum 10% duty cycle.

2. At 25 °C including initial tolerance, line voltage, load currents and output voltages adjusted to factory settings.

3. Peak-to-peak with 20 MHz bandwidth and 10 μF in parallel with a 0.1 μF capacitor at rated line voltage and load

ranges.

4. Minimum loads are required

5. Total current of all outputs can not exceed 21 A.

Electromagnetic

susceptibility:

Designed to meet IEC EN61000-4, -2, -3, -4, -5, -6, -8, -11 Level 3

Humidity:

Operating; non-condensing 5% to 95%

Vibration:

Three orthogonal axes, sweep at 1 oct/min, 5 min. dwell at four

major resonances 0.75 G peak 5 Hz to 500 Hz, operational

MTBF demonstrated:

>550,000 hours at full load and 25 °C ambient conditions

Environmental Specifications

Logic Control

Power failure

TTL logic signal goes high 100 - 500 msec after V1 output; It

goes low at least 4 msec before loss of regulation

Remote inhibit

Requires contact closure to inhibit outputs

Remote sense

Compensates for 0.5 V lead drop min. Will operate without

remote sense connected. Reverse connection protected.
