　　Product Description:

　　The 1746-P2 A-B SLC rack mounted power supply is an efficient,reliable,durable,easy-to-use,and powerful module that can provide power to PLC modules in the SLC 500 chassis.This module can meet different application requirements and is widely used in various industrial control fields.

　　Allen Bradley 1746-P2 is an SLC 500 power supply.The nominal input voltage of this power supply is 120/220 volts AC.Its internal current capacity is 5A(5V DC)and 0.96A(24V DC).It provides a 24VDC voltage output and has built-in fuse protection.

　　Allen Bradley 1746-P2 is an SLC 500 modular power supply.Its input voltage is 85-132 or 170-265V AC(47-63 Hz).Its internal current capacity is 5A at 5V and 0.96A at 24V.The power supply also has a maximum 15 A overcurrent protection and a maximum surge current of 20 A provided by the user.It has a typical line power requirement of 180 VA and an input terminal and backplane isolation of 1800 V AC RMS for 1 second.The user power supply current capacity at 24V DC is 200 mA,and the user power supply voltage range of the power supply(also 24V DC)is 18-30V DC.

　　Each terminal can have a maximum of two AWG wires.The 1746-P2 power supply has fuse protection,but only limited to preventing fires caused by short circuits.It comes with an open shell and can only be installed in a 1746 chassis.The entire power supply size is 5.5 x 2.9 x 5.7 inches and weighs 1.1 kilograms or 2.5 pounds.Its working temperature is 0-60℃.Celsius degrees.

　　This power module has a jumper terminal used to set the input voltage applied to the device.

　　When undervoltage operation occurs,the 1746-P2 power supply will continue to provide short-term power to the SLC 500 controller.When the power supply continuously receives input voltage below the recommended operating range and lasts longer than the CPU holding time,the controller will shut down.Only when the power supply receives the recommended working input voltage will it automatically resume operation.

　　For overcurrent situations,1746-P2 series A and B will experience power shutdown and CPU failure.The recovery process involves reloading the user program.For the 1746-P2 series C,it will have a 24V DC user shutdown,but the CPU will continue to run,and the recovery process is to correct the overcurrent situation.

　　1746-P2 is a power module designed primarily for use on the SLC 500 automation system platform.The power supply is installed on the far left side of the SLC chassis.

　　The installation location of this power supply is not included in the number of slots.The slot count starts from slot zero(0),which is reserved for programmable logic controller(PLC)processors or SLC 500 communication adapters.

　　When the front cover of the power supply is opened,the front panel of the power supply is exposed.This power supply has five(5)terminals,jumper pins,and internal fuses.These terminals are designed to accommodate AC line connections and DC power connections.A terminal is used as a grounding terminal.Internal fuses have replacement parts 1746-F2 with the same part number.Jumper pins are used to set the correct input voltage settings,whether it is 100/120 VAC or 200/240 VAC.

　　Avoid generating arcs when working with a power source.Disconnecting or connecting the wires of the active power supply may generate an arc,which can damage the electronic backplane.It is very important to perform operations when the input power is inactive.The power module itself is sensitive to voltage surges that may occur when starting high inductance electrical loads.To avoid damaging the power module,an isolation transformer can be installed to prevent voltage surges from entering the power supply.

　　The holding time of this power supply is 20 ms(full load)and 3000 ms(no load).Even if the input voltage of the power supply is lower than the nominal power level,this function allows the PLC processor to continue running.

　　The 1746-P2 A-B SLC rack mounted power supply is a metal module with 2 input terminals and 1 output terminal.The input terminal receives a 115-230 V AC power supply,and the output terminal provides a 24 V DC power supply.This module also has functions such as overcurrent protection,overvoltage protection,and short circuit protection.
