 Technical guidance notes

Test conditions for the above parameters: 230VAC input, rated load, 25 °C 70% RH. Humidity Tolerance: includes set up tolerance, line regulation, load stability (Note 5) Ripple Test: 20MHz with A12 "twisted pair terminal with a 0.1uF & 47uF capacitor short-circuit Line Regulation test: full-load into the line of low to high voltage Load regulation test: load from 0% to 100%, other 60% of rated output load The maximum current output of up to, but the total load can not exceed the maximum output power

We do have some battery chargers in different other models.
