User information
The TMAA13 is a switched mode power supply. It converts mains
input voltage to regulated 13.8V
DC
using pulse-width modulation
(PWM) control.
To avoid any issues that may be caused by simultaneous
transmissions, there should be one TMAA13 per radio.
The TMAA13 power supply is protected against short circuits, as
well as over-current and over-voltage conditions. It also offers over-
temperature shutdown.
Check the mains supply voltage
Before you plug in and turn on the power supply for the first time,
please check the mains supply voltage.
The voltage rating of the power supply is printed on a label on the
bottom of the unit. Verify that it corresponds with your local mains
supply voltage (that is, 120V
AC
or 230V
AC
).
