APPLICATIONS
The B_M-2WR2 Series are designed for application where
isolated output is required from a distributed power system.
These products apply to where:
1) Input voltage rang ≤ ±10%;
2) 1500VDC input and output isolation;
3) Regulated and low ripple noise is not required.
Such as: digital circuits, low frequency analog circuits.
