To order extended warranty product add the suffix –EX to your required part number3, example -LFMWLP350-1001-EX (See Note 3)
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 +/-10 % and Ripple and noise is less than 10 %.
  • Specifications are for nominal input voltage, 25°C unless otherwise stated.
  • Thermal shutdown feature : The power supply goes in hiccup mode when the temperature of PCB exceeds 110 °C (+/-10 °C).
  • 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."
Notes:
  1. Ripple is peak to peak with 20 MHz bandwidth and 10 μF (Tantalum capacitor) in parallel with a 0.1 μF capacitor at rated line voltage and load ranges.
  2. Output ripple can be more than 10 % of the output voltage.
  3. .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.
