Description
The PT3340 series is a single-output
isolated DC/DC converter, housed in a
19-pin aluminum SIP package. These
modules are UL, CSA, and VDE ap-
proved for telecom applications, and
rated at 30W or 8A. The 18V to 60V
input range allows easy integration into
many distributed power applications which
utilize 24V bus architectures.
Standard output voltages range from
1.8V to 15V, and are each adjustable by
up to ±10%. Operating features include
a Remote On/Off control, an under-voltage
lockout (UVLO), and a differential re-
mote sense. Protection features include
an output current limit, short-circuit
protection, and over-temperature shut-
down.
A 330F output capacitor is required
for proper operation.
