## Note : External supply voltage can be changed with pre Information ## Notes 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. Combined output power of main output, fan supply shall not exceed max. Power rating. 3. Fan supply output voltage tolerance including set point accuracy, line and load regulation is +/-10% and Ripple and noise is 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. 7. Models LFWLP350-1301 and LFWLP350-1302 do not have CCC approval 8. When used in Cover Kit, de-rate output power to 70 % under all operating conditions. 9.
