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
Isolation resistance
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits and IGBT power device
driven circuits, etc.

Note: The D_T-W2/W5 series also are available in our company.
