Page 8 - Soldering and Cleaning Considerations; DESIGN CONSIDERATIONS; Input Source Impedance

DS_H48SV05030_08102007 8 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. A SELV reliability test is conducted...

Page 9 - FEATURES DESCRIPTIONS; Over-Voltage Protection; Vout

FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will automatically shut down (hiccup...

DS_H48SV05030_08102007 11 THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of he...
