Product Description:
The PRD-P306250z-45 is a closed-loop servo amplifier manufactured by Kollmorgen for the SP Servostar Servo Drives series. The device converts incoming AC mains power into a regulated DC bus and high-frequency PWM phases that drive brushless servomotors. Within an automation line, it delivers commanded torque, velocity, and position to axes used in packaging, electronics assembly, and material-handling stations. Its compact design and fast transient response support demanding applications with high-duty cycles.
The power stage supplies a continuous phase current of 6 A, while short bursts can reach 12 A to handle acceleration peaks. When operated on 230 VAC mains, the converter can deliver 2.2 kW to the motor terminals. Current is modulated at a carrier frequency of 16 kHz, shifting audible noise above the human hearing range and improving torque smoothness. An overvoltage shutdown trips at 430 VDC to protect the DC bus. The analog control section draws 320 mA, and an 8 VDC logic rail supplies the onboard DSP. A remote-enable opto-input sinks 20 mA, allowing upstream safety relays to control drive operation without placing excessive demand on their contacts.
Thermal protection disables the output at 118 °C, while cabinet airflow must remove the unit’s internal heat dissipation of 84 W. Startup remains inhibited until the DC bus rises above the 90 VDC undervoltage threshold. When connected to a 115 VAC supply, the unit is rated for 1.1 kW. The analog reference input accepts ±15 VDC, permitting a direct interface with compatible motion controllers. The housing measures 75 mm wide, 202 mm deep, and 264 mm high, allowing multiple axes to be installed side by side on standard DIN subpanels. Adequate spacing around the housing helps cabinet airflow carry generated heat away from the power electronics during continuous operation.
