The LOF series currently consists of 3 open frame families in industry-standard packages.

Each family is available with outputs ranging from 12V to 48V with the following additional features:

  • Universal AC Input (85 – 275Vac) with PFC
  • Operating temperature – 40 °C to +70°C
  • Convection and forced air-cooled ratings
  • Efficiency up to 95%
  • Very low earth leakage (<0.1mA)
  • No-load power consumption < 0.5W
  • High surge withstand (300Vac for 5 secs)
  • Compliance to IEC/EN/UL62368, IEC/EN60335, IEC/EN61558, GB4943, IEC/EN/ES60601

High Efficiency + Good Thermal Design = High Reliability + Long Life

The LOF Series have been designed using state of the art topologies and components, resulting in a family of power supplies with excellent ripple and dynamic performance.  The units have been designed to minimise local temperature hotspots, therefore improving system reliability, and increasing the life of the AC-DC Converters.
