To order extended warranty product add the suffix –EX to your required part number5, example - LFMWLP225-1001-EX (See Note 5)
General Notes:
  • Combined output power of main output, fan supply shall not exceed max. Power rating.
  • Fan supply output voltage tolerance including set point accuracy, line and load regulation is +/-15 % and Ripple and noise is less than 10 %.
    With V1 fully loaded, Vfan need to have min load of 20mA to be within regulation band.
  • Specifications are for nominal input voltage, 25°C unless otherwise stated.
  • When used in Cover Kit, de-rate output power to 70 % under all operating conditions
  • Class II version available, Add "-II" suffix at the end of the Model Number.
  1. Ripple is peak to peak with 20 MHz bandwidth and 10 µF (Electrolytic capacitor) in parallel with a 0.1 µF capacitor at rated line voltage and load ranges.
  2. 225W with 13CFM forced air cooilng and 120W with natural convection cooling at 100 to 264VAC.
  3. Output ripple can be more than 10 % of the output voltage.
  4. Adjustment potentiometer is located on the SMT side of the PCB.
  5. The extended warranty period is 7 years from the date of manufacture and will continue for 6 months thereafter to allow for transport and stock holding prior to end customer receipt.
    The extended warranty is a “return to base” warranty and does not imply a guarantee of 7 year operation. The standard EOS warranty T & C ’s apply for the extended warranty period.
    Refer to your local EOS representative for further details.
