    Note 1. All parameters NOT specially mentioned are measured at 230V AC input, rated load and 25°C of ambient temperature.
    2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
    3. Tolerance includes set up tolerance, line regulation and load regulation.
    4. The switching power supply is considered a component which will be installed into final equipment. Please make sure that the final equipment still meets EMC directives.

    Tips: How to select switching power supply?
    1. Select appropriate specifications of input voltage.
    2. Select appropriate power. To extend life span of power supply, it is suggested to select a device with 30% more than rated output power.
    3. Consider load characteristics. In case of motors, bulbs or capacitive load, users should select appropriate power supply to prevent overload caused by large current at startup. In case of motors, users should consider backward flow of voltage when the device is halted.
    4. Users must consider working temperature of power supply and whether there are additional auxiliary coolers. Output of the power supply shall be reduced in higher temperature conditions.
    5. Select following features according to demands:
    Protective features: overvoltage protection (OVP), over temperature protection (OTP), and over load protection (OLP) etc.
    Application features: signal functions (indication of normal and failure status), remote control, remote measuring, and parallel connection etc.
    Special features: power factor correction (PFC), and uninterrupted power supply (UPS)
    6. Comply with applicable safety certification and EMC certification.
