1

Ripple and Noise are measured with 20MHz bandwidth, probe terminated with a 0.1

μF MKP parallel capacitor.

2

Pay attention, set the current limitation mode jumper on C.C. mode when connecting more units in parallel.

NOTE: Power rating, losses, efficiency, ripple, thermal behaviour and start-up may change outside of the nominal rated input range.
