Input voltage:85265VAC,4763Hz.The nominal input voltage is 120VAC/240VAC.

Rated output power:75W(at 0+60°C,+32+140°F).In some cases,the rated output power of this power supply is 140W when operating at-0+75°C(+32+167°F).

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.

Mounting Position:Installed on the far left side of the 1756 chassis,on the dedicated power supply slot.

AB 1756-PA75

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

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

Isolation Voltage:Rated at 250V(continuous),reinforced insulation type,power input to backplane type.Tested at 3500V DC for 60 seconds.

Other Features:

With a non-replaceable fuse designed to prevent fire hazards caused by short circuits.

Suitable for industrial environments with pollution level 2 and excessive Class II applications.

Can operate at altitudes up to 2000 meters without derating.

III.Features

High-speed communication interface:used for fast and reliable data exchange with servo motor drives.

Programming flexibility:supports multiple programming languages​​(such as ladder diagrams,instruction lists,etc.),which is convenient for users to program according to specific needs.

Rich diagnostic functions:provides real-time status monitoring,fault alarms and diagnostic information to help users quickly locate and solve problems.

Powerful expansion capabilities:can be combined with other ControlLogix series modules to meet various complex control needs.
