Page 9 - Soldering and Cleaning Considerations; DESIGN CONSIDERATIONS; Input Source Impedance

9 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 on the system where th...

Page 10 - 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...

Page 12 - THERMAL CONSIDERATIONS; Thermal Testing Setup; Figure 24: Wind Tunnel Test Setup; Thermal Derating

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 heat transfer. Hence, the ch...
