FEATURES
RoHS compliant
Triple outputs (-24V, -48V & -72V)
When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external
capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.

DESCRIPTION
The NMT series is a range of DC/DC convert-
ers offering three output voltages of -24V, -48V
and -72V from a single isolated 5V or 12V input
voltage. The product is designed for use with
telecommunications circuits requiring an on board
supply for the -72V RING-TIP connection service
generated from a nominal 5V or 12V DC input
supply rail. The device also offers battery level
voltages of -24V and -48V for access control and
