Product Description:
The Kollmorgen’s PSR45A-275 servo power supply is engineered for powering automation and motion control systems. It delivers a stable DC output essential for servo machinery and is configured for three-phase AC power systems. The PSR45A power supply is integrated with a Schaffner Model No. 258-75/34 filter to support clean and interference free power operation.
The PSR45A-275 power supply has operating input voltage range of 90 to 280 VAC and the output is rated at 310 VDC with a maximum of 75 A DC for multiple servo axes. The terminal torque for main power and bus connections is specified at 20 inch-pounds to match the torque required for the grounding studs for ensuring secure electrical bonding and safety compliance. The PSR45A power supply supports both RS-232 and RS-485 communication interfaces for seamless integration with modern control systems. It can be connected up to six BDS4 or BDS5 servo drives. The PSR45A power supply’s recommended UL-rated time delay fuse for the main power input to ensure reliable overcurrent protection is BUSS FRN-R series. The PSR45A power supply is attachable with 22–18-gauge wire sizes for signal and control and 16-gauge wire for power connections.
The PSR45A-275 power supply has a front panel that includes clear indicators for DC bus, regen and fault statuses while the terminals can be connected to an external regeneration resistor for power dissipation. A residual voltage protection system is built-in that requires a 5-minute wait after power removal. For optimal electrical connections with PSR45A power supply, 600 V AC insulated copper wires are recommended to have a minimum wire gauge of 8 for the power bus.
