Product Description:

The PRD-AMPB25EZ-00 is a servo amplifier produced by Kollmorgen for the PD Servostar Servo Drives series. The unit conditions low-voltage DC power and modulates it into a three-phase AC output that matches the torque and speed commands generated by motion controllers. By closing the electrical loop between a DC supply and a synchronous or induction motor, the drive regulates current precisely and provides the dynamic response required in automated pick-and-place stations, packaging lines, and similar machinery.

This model draws its control energy from a nominal input of 24 VDC and consumes up to 144 VA under rated load. Internally, pulse-width modulation operates at 16 kHz, producing a smooth sinusoidal waveform at the output stages while keeping switching losses modest. The amplifier can deliver a continuous phase current of 5 A RMS per phase, allowing it to support medium-frame servomotors without overheating. A 15 A supply fuse and a fault relay with a 1 A contact rating isolate the drive when abnormal conditions occur. Housing dimensions of 140 × 108 × 51 mm enable dense panel layouts, and the converter transfers up to 130 VA to the motor through an output voltage of 15 VAC. Short bursts, such as startup inrush, are handled with a 30 A surge rating, while an undervoltage cutoff protects the logic when the supply falls to 16 VDC.

The peak deliverable current rises to 10 A RMS, supplying extra torque during rapid acceleration. Protective circuitry trips if the DC bus climbs above 56 VDC or if the internal heat sinks reach 80 °C, preventing component stress. The unit weighs only 0.55 kg, so it can be mounted on lightweight machine frames without adding substantial mass. The protection circuits initiate a predictable shutdown whenever voltage, temperature, or load deviations threaten normal operation.
