Product Highlights
High-efficiency universal AC input with a fully regulated output power supply play an essential role in allowing the EnGenius open frame AC/DC power supply series to deliver high efficiency and optimize no-load performance. Our power supplies come in an open frame format, which means they feature printed circuit boards (PCBs) with no enclosure. Instead, the equipment running the power supply has its own enclosure that will protect the PCB.
  • Efficiency: 90%~93% at 230Vac at full load
  • With active Power Factor Correction
  • Over Voltage Protection
  • Over Current Protection
  • Short Circuit Protection
  • Zero Current Switching technology to reduce power dissipation
  • MTBF > 200,000 hours at 25°C full load
  • Operation altitude: 5000 meters
  • Surge protection: 4KV(L/N-PE) and KV(L-N)
  • Can withstand 300Vac input voltage for 1 minute
  • PoE Isolation
