DS_S48SP3R310_05222008 7 The input source must be insulated from the ac mains by reinforced or double insulation. The input terminals of the module are not operator accessible. If the metal baseplate is grounded , one Vi pin and one Vo pin shall also be grounded.
DS_S48SP3R310_05222008 8 FEA TURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-curre nt protection circuit, which will endure current limiting for an unlimited duration during output overload.
DS_S48SP3R310_05222008 9 FEA TURES DESCRIPTIONS (CON.) Output V oltage Adjustment To increase or decrea se the output voltage set poi nt, the modules may be connected wit h an external resistor between the TRIM pin and either the Vo (+) or Vo(-). The TRIM pin should be left open if this feature is not used.
DS_S48SP3R310_05222008 10 THERMAL CONSIDERA TIONS Thermal management is an importa nt part of the system design. To ensure prop er, reliable operation, suffici ent cooling of the power mod ule is needed over the entire temperature range of the modul e.
