01 /Overview
Product details
Dragonfly is a 1U rack-mount industrial power supply that delivers 1000 W of continuous output at 57 VDC / 20 A from a universal AC line, sized for high-port-count PoE network switches.
Active power-factor correction (≥ 0.95) and 4.25 kV isolation keep it grid-friendly and safe, while active cooling with thermal feedback holds output across a wide −20 °C to +85 °C range. Auto-recovering OVP, OCP, SCP and OTP guard the load.
