APPLICATIONS
The IB_S-2W Series are specially designed
for applications where a single power supply is
highly isolated from the input power supply in a
distributed power supply system on a circuit
board.
* Designing.
These products apply to:
1) Where the voltage of the input power supply
is fixed (voltage variation ≤±5%);
2) Where isolation is necessary between input
and output (isolation voltage ≤1000VDC);

with proper resistance at the output end in parallel to increase the load, or use our
company’s products with a lower rated output power.
