±15
The WRA_YS-3W&WRB_YS-3W Series
are specially designed for applications where a
wide range input voltage power supplies are
isolated from the input power supply in a
distributed power supply system on a circuit
board.
NOTE:
Case material:non-conductive plastic
Weight: 4.8g (0.17oz)
These products apply to:
1) Where the voltage of the input power
supply is wide range
