APPLICATION
The WRB_LT-3WR2 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.
1) These products apply to where: Input voltage range≤2:1;
2) 1.5KV input and output isolation;
3) Regulated and low ripple noise is required.
