  • Operating Temperature Range: -40º to +85º C (Baseplate)
  • Standard Full Prick Footprint: 2.0” x 4.5” x 7.5”
  • High Efficiency: ~91%
AC Input
  • Voltage Input Range: 90-264VAC (nominal range)
  • Frequency: 47-440Hz
  • Phase: Single Phase, 2 wire plus ground
  • Inrush Current: <40A  (Cold Start at 200Vac)
  • Power Factor Correction: .95 minimum, meets EN61000-3-2
  • Start-Up Time: <500mSec (Output within regulation)
  • Input Surge Voltage: Input transient suppression circuitry to protect power supply from permanent damage.
