    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. Combined output power of main output, fan supply shall not exceed the max. Power rating.
    3. Fan supply output voltage tolerance including set point accuracy, line, and load regulation is +/-10% and Ripple and noise are less than 10%.
    4. Specifications are for nominal input voltage, 25°C unless otherwise stated.
    5. Thermal shutdown feature: The power supply goes in hiccup mode when the temperature of PCB exceeds 110 °C (+/-10 °C).
    6. Output ripple can be more than 10% of the output voltage.
