OPERATING INFORMATION
13.1
Input Voltage. The TMN/TMP Series modules operate off worldwide AC
input voltages within the range of 85 to 264 VAC (TMN) or 170-264VAC
(TMP), at 47 to 63 Hz. There is a separate input connection for each
module to a terminal block at the rear of the rack mount. For complete
details see Section 18.2 and Figure 5.
13.2
Output Connection. The 24V, 28V or 48V output is provided on two
copper bus bars. Each bus bar has four 1/4-inch holes. Connection
should be made by means of 1/4-inch diameter bolts. For complete details
see Section 18.3 and Figure 5. Both positive and negative outputs are
floating and isolated from the chassis.
13.3
Output Voltage. The output voltage of each module is factory set to 24,
28 or 48 volts, ±1%. The voltages, however, may be adjusted by means of
the front panel potentiometer or the voltage adjust input pin.
13.4
Output Power. Maximum output current for a TMP module is 50A at 24
VDC, 43A at 28VDC or 25A at 48VDC, giving a maximum output power of
1200 watts. For a TMN module, maximum output power is 1000 watts.
The maximum output power of a module may be drawn at up to 50
o
C
ambient temperature. Above 50
o
C the output current must be derated by
2.5%/
o
C. See Figure 6. The maximum operating temperature is 70
o
C, at
which the output current must be derated by 50%.
13.5
Output Overload Protection. Each module output is protected from
damage due to overload or other short circuit condition. This protection is
continuous and without damage; recovery is automatic when the overload
or short is removed. The current limit characteristic is a constant current
above 40V, 23V or 20V (depending on model). Current limiting takes
place at approximately 105% of the rated output current.
