DESCRIPTION OF FEATURES & OPTIONS
DESCRIPTION
The input current is a sine wave in-phase with the input voltage
to give a power factor of 0.99. Input current total harmonic
distortion meets EN61000-3-2.
The AC input range is continuous from 85 to 265VAC (TMN) or
170 to 264VAC (TMP), 47-63Hz, for worldwide operation.
This filter suppresses conducted noise from the module back
onto the AC line. The filter meets FCC20780 part 15J Curve B
and EN55022 Curve B.
When the module is turned on from a cold start, the initial input
current is limited to a peak value of 50 amperes.
For a 48V unit the adjustment range is 45V to 58V. For a 24V
model the adjustment range is 22.5V to 29V. The adjustment is
made from the front panel by means of a 12-turn potentiometer
or from the input to the remote adjust terminal.
This input is used to remotely adjust each module output
voltage. An analog voltage from 0 to +5V controls approxi-
mately 45-58V output for a 48V module or 22.5-29V output for a
24V module. The analog inputs can also be connected together
so that the external control voltage adjusts all the module
outputs simultaneously.
If the output power converter overheats, the TMN/TMP module
will automatically shut down. The DC Good LED also turns off.
After a few minutes the module will cool and automatically start
up again.
The TMN/TMP modules are automatically connected to current
share with each other when they are inserted into the rack. A
single-wire connection provides this. The modules current share
with an accuracy of 10% of their full load output current for total
loads of 50% to 100%. The rack current share pin can be used
to current share with another rack of the same output voltage.
This diode in series with each module output protects the
parallel-connected modules. If the output of one module fails to
a short or to a lower than normal output voltage, the other
modules are not affected. Also when hot-swapping modules,
the diode prevents a glitch in the output voltage while the output
is still rising on the inserted module.
