1756-PA72 Description

The 1756-PA72 is a Standard Power Supply that is mainly used to deliver power to 

the backplane of a 1756 chassis, enabling each of module attached to the chassis to 

operate. The 1756-PA72 is designed to accept an input voltage range of 85-265 VAC 

with frequency range of 47-63 Hz. It delivers an output power of 75 W @ 0-60 °C 

(+32…+140 °F) with Current capacities of 4A at 3.3VDC; 10 A at 5.1VDC and 

2.8 A at 24VDC.

The 1756-PA72 has a hold-up time of 5 cycles @ 85VAC, 50/60 Hz; 6 cycles @ 

120VAC, 50/60 Hz; 6 cycles @ 200VAC, 50/60 Hz and 6 cycles @ 240V AC, 

50/60 Hz. Hold-up time refers to the power supply’s reaction from the removal 

of the input voltage and DC power failure.

The 1756-PA72 is installed at the left most location of the chassis. It has a dedicated 

slot assignment, outside the chassis and does not occupy a slot. It may be installed 

in different chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 

1756-A17, whether Series A, B and C. This power supply weighs approximately 

0.16 kg with physical dimensions of 11x14.4x14cm. This module, along the chassis 

has an open-type enclosure, therefore, requires installation inside an enclosure that 

protects the hardware from industrial contaminants and interferences. The 

1756-PA72 may not be used is redundant power supply applications however, 

it may also be used in Distributed I/O architecture.

The 1756-PA72 has a power consumption of 25 Watts at 0 to 60 degrees Celsius 

(32 to 140 degrees Fahrenheit). This power supply has a power dissipation of 85.3 

BTU/hour and a power supply with a maximum inrush current of 20 A. The 

1756-PA72 provides built-in overcurrent protection. It is user-supplied at a maximum 

of 15 A. The maximum transformer load of this power supply is 100VA and the 

voltage isolation is 250 Volts continuous. The 1756-PA72 also has a reinforced 

insulation type tested at 3500 Volts DC for 60 seconds. The 1756-PA72 is open 

type equipment. This power supply should be installed in an appropriate enclosure 

that is designed for certain environmental conditions. The inside of the enclosure 

should be accessible only with a tool. Please see the user manual from the NEMA 

Standard 250 and IEC 60529 publications for an explanation of the level of 

protection afforded by different types of enclosures.
