  1. “*” are models being developing; Suffix “C” is with CTRL function;
  2. ”-T” suffix for chassis mounting”-TS” suffix for DIN-Rail mounting, DIN-Rail width is: 35mm
  3. Max capacitive load is, when the power supply is fully loaded, the max capacity could be connected to output, if exceed, the power supply cannot start-up;
  4. To reduce no load power consumption and improve efficiency of light-load, IC will be flitter frequency under no-load and light-load operating, output cannot be no load, at least with 5% load or above 470uF high frequency low resistance electrolytic capacitor, otherwise the output ripple will rise;
