APPLICATIONS
The D_T-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) Where the voltage of the input power
supply is fixed (voltage variation ≤±10%);
2) Where isolation is necessary between input
and output (isolation voltage ≤1000VDC);
3) Where the regulation of the output voltage
and the output ripple and noise are not
demanding.
