Product Description:
The PSU-45 is an Okuma power supply module in the PSU Servo Power Supplies series. Classified as an axis and spindle drive energy source, the unit converts factory mains into a stabilized DC bus for servo amplifiers that position cutting tools and rotate spindles. By separating high-current conversion from the individual inverters, the module simplifies cabinet wiring, concentrates heat generation in one enclosure, and gives machine controllers predictable voltage during rapid load changes. In a centralized drive cabinet, that division can also make thermal management and bus distribution easier across several motion channels.
This supply accepts three-phase AC line power. The allowable frequency ceiling is 60 Hz, and the upper voltage limit is 230 V, which fits common industrial distribution systems. When utility levels dip, the converter keeps operating down to 200 V, helping the machine continue through moderate sags without shutdown. Okuma classifies it as an axis/spindle drive supply, which means the rectifier is intended for recurring regenerative bursts and high dynamic currents during coordinated motion. Because the supply is separate from the amplifier stages, it can serve as the common energy source for several connected axes in the same cabinet. A short-circuit withstand rating of 50 kA lets upstream protection clear faults safely, and the unit type indicates that the module is dedicated to bulk power conversion rather than control or feedback functions.
The lower bound of the permitted line frequency is 50 Hz, so the same module can run on either standard utility frequency. On the DC side, conversion produces a voltage window from 283 V to 325 V, which suits servo drives that use capacitor banks to absorb regenerative energy on the bus. The DC bus level remains appropriate for linked servo sections that must respond quickly during acceleration, deceleration, and spindle speed changes. Continuous transfer capability is rated at 45 kW, providing headroom for multi-axis machining centers or large turning applications. Its output is DC, matching the input requirements of Okuma servo amplifiers and spindle inverters without further conditioning.
