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

Overload Protection
Under normal operating conditions, the output circuit
of these products has no protection against overload.
The simplest method is to connect a self-recovery fuse
in series at the input end or add a circuit breaker to the
circuit.
No parallel connection or plug and play.
