320W Dual Redundant Hot-Swap ATX PS/2
[PS26]

PS26
320W ATX Mini Redundant Power Supply Specification Sheet
This specification defines the electrical performance and characteristics of the ESA Model PS26 320W Mini Redundant Power Supply. The backplane is designed with only passive components. This is key for a longer MTBF. The units also offer a warning sub-system including LED display, buzzer alarm, and TTL Signal so the user can quickly observe power supply status. The parallel design of facilitates load balancing which boosts reliability.


Features

  • True redundant design (passive backplane)
  • All active circuits designed into the power module
  • Hot-swap and hot-plug Redundancy Function
  • Full range (90VAC ? 264VAC) operation
  • Active Power Factor Correction (PFC) full range, Meets IEC-1000-3-2 Class D
  • Balanced load sharing design
  • Remote sensing design
  • EMI Noise Filter: FCC Class B, CISPR22 CLASS B
  • Fault free- slide rail design
  • Isolated rail design to meet safety regulation
  • Cooling: Two 40 mm DC FANS (MODULE)
  • Compact size (PS2 form factor)
  • Single AC Inlet
