Product Description:
The PSR3-230/75-21-205 servo power supply is from Kollmorgen, a well-known industrial automation company. This unit is designed to power servo motors in demanding applications. One important spec is the rated operational voltage of 690V AC. This is the maximum voltage the unit can handle during operation. Along with this is the continuous current rating of 90A, which is the amount of current the power supply can deliver continuously. These two specs are key in determining the power output and, therefore, the capability of the power supply to drive specific servo motors. It also has IP54 ingress protection. This means the enclosure can protect against dust and water splashes, which is important in industrial environments where such hazards are common. DIN rail mounting makes installation easy, a standard method of mounting industrial control equipment, and saves time and effort during setup.
The Kollmorgen PSR3-230/75-21-205 has a switching capacity of 100 kVA. This is the power supply's ability to handle rapid changes in load, which is important for dynamic servo motor control. The power supply accepts a main AC line input voltage of 160-253 VAC and a control AC line input voltage of 90-132 VAC and has multiple power supply configurations. It produces a main DC bus output voltage of 325 VDC, which is a stable and regulated power source for the connected servo drives. The peak dissipation of 11.2 kW is the maximum amount of power the unit can dissipate as heat during transient operations. The continuous dissipation is 40W, and the internal heat dissipation is 150W, which is important for thermal management and to ensure the longevity of the device.
Other specs include a soft-start surge current (max) of 150 A. This is important for limiting the inrush current when the power supply is turned on to prevent damage to the unit and the circuit. External shunt regulator current (peak) of 44.3 A is the maximum current the shunt regulator can handle, which is important for controlling DC bus voltage during braking or regenerative operations. Charge time (max) of 25 msec is the maximum time it takes for the DC bus capacitor to charge to its operating voltage, which affects the system's startup time. Peak external power dissipation of 17.3 kW is the maximum power that can be dissipated externally, which is often through a braking resistor during regenerative braking.
