Note:
①When
input 85-100VAC/100-120VDC, it need to be voltage derated on basis of temperature derating;
②Altitude
should be derated based on temperature derating when it is 3000 - 5000m;
③This
product is suitable for use in natural air cooling environments, if in a closed environment, please contact our company’s FAE.

Note:
Note: Output filtering capacitors C2 is electrolytic capacitor, it is recommended to use high frequency and low impedance electrolytic capacitor. For
capacitance and current of capacitor please refer to manufacture’s datasheet. Capacitor voltage reduced to at least 80%. C1 is ceramic capacitor, which is
used to filter high-frequency noise, advice use 1
