APPLICATION
The WRA_S-1WR2 & WRB_S-1WR2 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. For these
DC-DC converters, you can reduce the failure points of design,
and save the m anpower, material and time cost in developing
micro power supply, and also ensure better quality, stability,
safety protection, and reliability for the end products.
These products apply to where:
1) Input voltage range ≤2:1;
2) Input and output isolation ≤1.5KVDC;
3) Regulated and low ripple noise is required.
Such as: industrial control, tele-communications etc.
