1. The given parameters (unless otherwise stated) have been measured for a 230VAC supply voltage, rated load at an ambient temperature of 25 ° C.

2. Ripples and noise were measured for the 20 MHz band using twisted test leads and 0.1μF and 47μ capacitors connected in parallel.

3. Tolerance expresses the maximum difference of the output voltage taking into account changes in switching on, depending on the changes of the input voltage and depending on changes in the load current.

4. The time of determination and rise is measured in the range of 0 ÷ 90% of the rated output voltage.

5. The power supply is in accordance with EN 61204-3 a subassembly not intended for assembly by the end user. In order to ensure compliance with compatibility standards can
it is necessary to use additional elements such as a network filter (eg 06IB2S) and / or ferrites (eg 74271222) on the in and out ducts. For the final device containing the power supply, it is necessary to perform tests again in order to verify the fulfillment of the whole system standards.
