A-B 1756-PA75

A-B 1756-PA75 is a ControlLogix power module produced by Allen-Bradley(A-B for short).The following is a detailed introduction to the product:

1.Product Overview

A-B 1756-PA75 is a standard power module that is installed on the leftmost dedicated power slot of the 1756 chassis and provides the necessary backplane power for each module installed in the chassis,enabling the module to be powered on and enter the operating state.

2.Technical Specifications

Input voltage:85265VAC,4763Hz.Compatible with 85264VAC voltage range,frequency is 4763Hz,and nominal input voltage is 120VAC/240VAC.

Output power:At 0+60°C(+32+140°F),the rated output power is 75W.Under certain conditions,such as operating at 75+0°C(+60+32°F),the rated output power can reach 140W.

Current Capacity:

At 4.3VDC,the current capacity is 3A.

At 13.5VDC,the current capacity is 1A.

At 2VDC,the current capacity is 8.24A.

At 5.1V,the current capacity is 13A(this value may vary depending on the specific product).

Hold-up Time:If the working input power is suddenly interrupted,this standard power supply can provide a certain hold-up time,specifically 2 cycles of hold-up time 85VAC,60 Hz 6 cycles 120VAC,60 Hz 20 sections 220VAC,60 Hz.

Isolation Voltage:Has an isolation voltage rating of 250V(continuous),reinforced insulation type,power input to backplane type,tested at 3500V DC for 60 seconds.

3.Product Features

Compatibility:Compatible with various ControlLogix chassis,such as 1756-A4,1756-A7,1756-A10,1756-A13,1756-A17,etc.,as well as B series and C series chassis.

Installation location:Must be installed on the left side of the 1756 chassis and has a non-replaceable fuse designed to prevent fire hazards caused by short circuits.

Environmental adaptability:Suitable for industrial environments with pollution level 2 and excessive Class II applications(as defined in the IEC 60664-1 publication).At the same time,the power supply can operate at an altitude of up to 2000 meters without derating.

Warranty and service:Provide one-year free warranty service(specific warranty terms may vary depending on the seller).
