- Rack/Shelf: 4.15 lbs (1.88 kg)
NOTES:
- No load to full load, including line regulation and load regulation.
- Whichever is greater. 20MHz bandwidth. Measure with 0.1μF ceramic and 10μF tantalum capacitors in parallel across the output.
- <4% deviation recovering to within 1% for 25% load change.
- Typical efficiency is at low end of range for 12V output and at high end of range for 24V output.
- Intput-output isolation figure is for isolation components only. 100% production hipot tested input to ground.
