The 1756-PA75 is an Allen-Bradley Standard power supply. This
module is installed on the dedicated power supply slot, located at
the left most side any ControlLogix chassis. The primary purpose of
this power supply is to deliver the necessary backplane power, used
by each of the modules installed to the chassis. This backplane
power energizes the modules to enter operational state.
The 1756-PA75 must be supplied with an external power to operate.
It is compatible with 85-264VAC voltage range along a frequency of
47-63 Hz while the nominal input voltage are 120VAC / 240VAC. This
power supply has an output power rating of 75 W when operated at
0…+60 °C (+32…+140 °F) and current capacities of 4A at 3.3VDC; 13 A
at 5.1VDC and 2.8 A at 24VDC.
The 1756-PA75 is compatible with a variety of ControlLogix chassis
such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 and of
chassis series, particularly Series B and Series C. if operating
input supply to the 1756-PA75 is suddenly interrupted, this
standard power supply provides a hold-up time of 2 cycles @ 85V AC,
60 Hz 6 cycles @ 120V AC, 60 Hz 20 cycles @ 220V AC, 60 Hz.
Additionally, it has an isolation voltage of rating of 250V
(continuous), Reinforced Insulation Type, Power Input to Backplane
Type tested at 3500V DC for 60 s.
The 1756-PA75 requires hardware configuration.
The Allen-Bradley 1756-PA75 comes with a current capacity at 5.1V
of 13 A. This power supply must be mounted on the left side of 1756
chassis and it has a non-replaceable fuse that intended to guard
against fire hazards from short circuits. The 1756-PA75 is intended
for use in Pollution Level 2 Industry Environments and in excessive
Category II applications (as defined in the publication of IEC
60664-1). Note that the 1756-PA75 power supply can operate at an
altitude of up to 2000 meters without derating.
