Product Description:
The 3PS752.9 Power Supply Module is a reliable unit for PLC systems. It supports a wide input range and provides stable internal voltages. The model ensures efficient performance and system protection.
The 3PS752.9 power supply module from B & R Automation operates with an input voltage of 230 V AC or 220 V DC and consumes 50 W. It includes an expansion slave configuration. The unit integrates a 6.3 A slow blow 250 V glass fuse that offers protection against reverse polarity and overloads. The fuse compartment is conveniently located behind the module door. It generates internal voltages from a 24 VDC input voltage that is critical for PLC operations. Each main and expansion unit requires a dedicated power supply module. The module must be placed in the far left backplane slot and occupies two slots. The READY relay contact features a normally open design. It supports a maximum switching voltage of 30 VDC and a maximum switching current of 3 A. It provides transient voltage protection using a 370 V diode to ground. The maximum current requirement for the power supply module is 3.5 A. The input capacitance of the power supply module is specified at 500 µF that ensures stable operation under varying loads.
The 3PS752.9 power supply module is belong to the 2005 series module and ensures reliable performance under demanding industrial conditions. The power supply module features an integrated current limiting circuit that provides short circuit protection and ensures the module remains protected against overcurrent conditions. This current limitation is automatically activated not only during direct short circuits but also when the cumulative load demand exceeds the maximum rated output capacity of the power supply.
Frequently Asked Questions about 3PS752.9:
Q: Can the 3PS752.9 power supply module handle fluctuating loads without performance loss?
A: Yes, the 3PS752.9 power supply module ensures stable performance using its 500 µF input capacitance. This helps maintain voltage stability even during varying load conditions.
Q: Does the 3PS752.9 power supply module provide any built-in protection against overcurrent events?
A: Yes, it includes an integrated current limiting circuit. This activates automatically during short circuits or when load demand exceeds the maximum output capacity.
Q: Where should the 3PS752.9 power supply module be positioned in a PLC backplane configuration?
A: The module must be installed in the far left backplane slot. It occupies two slots and ensures correct power distribution to connected units.
Q: How does the 3PS752.9 power supply module from B & R Automation protect against reverse polarity?
A: It integrates a 6.3 A slow blow 250 V glass fuse for reverse polarity and overload protection. The fuse compartment is located behind the module door.
Q: Can the READY relay contact of the 3PS752.9 power supply module handle high switching loads?
A: The READY relay contact supports a maximum switching voltage of 30 VDC. It also handles a maximum switching current of 3 A efficiently.
