APPLICATIONS
The AY_D-1W & BY_D-1W Series are
specially designed for applications where a
group of polar power supplies are isolated from
the input power supply in a distributed power
supply system on a circuit board.
These products apply to:
1)
2)
input
3)
Where the voltage of the input power
Where isolation is necessary between
and
output
(isolation
voltage
supply is fixed (voltage variation
≤ ±10%);

Where the regulation of the output
voltage and the output ripple noise are not
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power
device driving circuits.
*Test ripple and noise by
“parallel

Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the
life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
3. In this datasheet, all the test methods of indications are based on corporate standards.
4. Only typical models listed, other models may be different, please contact our technical person for more details.
