(2) load regulation is measured at 115vac or 230vac in percentage to indicate the change in output voltage as the load varied f rom half load to full load ( ? %). (3) the exact obtainable load regulation depends upon the output cord selected and load current. (4) due to requests in market and advances in technology, specifications subject to change without notice. for the details of safety approval, please consult the factory. specification input specification input voltage: typical 90-264vac. input connector: 3 pole ac inlet iec320-c14(dt7) / 2 pole ac inlet iec320-c8(dt8). input frequency: 47-63hz. inrush current: 105a peak at 230vac. input current: typical 0.9a at 115vac/ 0.57a at 230vac. dielectric withstand: meet iec60601-1 & iec60950-1. emi: meet en55011 & en55022 / fcc class b. hold-up time: typical 12ms at 115vac. typical 70ms at 230vac. over temp. protection: optional (ntc circuit). earth leakage current (class i): less than 0.3 ma. touch leakage current (class i & ii): less than 0.1ma. no load power: less than 0.3w at 230vac
