{"product_id":"psr45-212","title":"PSR4\/5-212","description":"\u003cp\u003eThe \u003cstrong\u003eKollmorgen PSR4\/5-212\u003c\/strong\u003e is an industrial-grade servo power supply in the \u003cstrong\u003ePSR Servo Power Supplies series\u003c\/strong\u003e, designed to deliver robust and reliable performance in demanding automation environments. This unit provides \u003cstrong\u003e3.6 kW output power\u003c\/strong\u003e through a regulated DC bus and features a nominal \u003cstrong\u003e310 VDC output voltage\u003c\/strong\u003e to drive high-performance servo axes. Built for versatility, the PSR4\/5-212 accepts a wide range of input configurations, supporting 1 to 3 phase operation and ensuring compatibility with global power systems. With a continuous current rating of \u003cstrong\u003e12 Amps continuous current\u003c\/strong\u003e, the power supply maintains steady energy delivery under sustained loads, while its ability to source \u003cstrong\u003e48 Amps peak current for 50 msec\u003c\/strong\u003e addresses transient demands and acceleration peaks without system interruption. Rugged construction and precision control electronics make this unit a cornerstone component for high-precision motion control applications.\u003c\/p\u003e\n\n\u003cp\u003eThe PSR4\/5-212’s electrical characteristics are defined by a comprehensive set of specifications. It accepts a \u003cstrong\u003e160-253 VAC main AC line input voltage\u003c\/strong\u003e at a \u003cstrong\u003efrequency of 47-63 Hz\u003c\/strong\u003e, ensuring stable operation across regional power networks. The separate control electronics are powered by a \u003cstrong\u003e90-132 VAC control AC line input voltage\u003c\/strong\u003e, isolating logic circuits from main bus disturbances. Phase flexibility is guaranteed by its \u003cstrong\u003e1-3 phase input capability\u003c\/strong\u003e, allowing retrofit into existing infrastructures. Transient compensation is managed through a \u003cstrong\u003esoft start surge current of 150 Amp\u003c\/strong\u003e, limiting inrush at power-up, while a \u003cstrong\u003echarge time of 25 msec max\u003c\/strong\u003e ensures rapid readiness. Peak current handling includes \u003cstrong\u003e20 Amps (50 msec RMS\/phase)\u003c\/strong\u003e and \u003cstrong\u003e24 Amps (2 sec RMS\/phase)\u003c\/strong\u003e, delivering short-term high current bursts. Continuous dissipation is specified as \u003cstrong\u003e40 W power dissipation\u003c\/strong\u003e, with an \u003cstrong\u003einternal heat dissipation of 120 W\u003c\/strong\u003e managed through integrated thermal pathways. The built-in \u003cstrong\u003e15 Amp shunt regulator current\u003c\/strong\u003e protects against overvoltage and supports regenerative energy recirculation.\u003c\/p\u003e\n\n\u003cp\u003eOperational performance is optimized for efficiency and reliability. The shunt regulator dissipates excess energy during regenerative braking, maintaining DC bus stability and protecting downstream drives. Thermal management is achieved via low-resistance current paths and integrated heat sinks, ensuring that \u003cstrong\u003e120 W internal heat dissipation\u003c\/strong\u003e does not degrade long-term reliability. Fast transient response is secured by the \u003cstrong\u003e25 msec charge time\u003c\/strong\u003e, minimizing DC bus voltage sag during load changes. Soft start circuitry limits inrush to \u003cstrong\u003e150 Amp\u003c\/strong\u003e, reducing mechanical stress on upstream fuses and contactors, while peak current capabilities of \u003cstrong\u003e48 Amps for 50 msec\u003c\/strong\u003e and \u003cstrong\u003e24 Amps for 2 sec\u003c\/strong\u003e accommodate rapid acceleration profiles in robotics and machine tool axes. Protective monitoring of DC voltage, current, and temperature enables safe shutdown in fault conditions.\u003c\/p\u003e\n\n\u003cp\u003eSystem integration is streamlined through standardized interfaces and mounting provisions, facilitating incorporation into Kollmorgen and third-party servo drive cabinets. The PSR4\/5-212’s remote inhibit and fault signaling support centralized control architectures and predictive maintenance schemes. Its compact footprint and multi-phase input versatility make it well suited for CNC machines, packaging lines, robot cells, and printing presses. Engineers targeting high-precision motion control and energy-recovering drive systems will find the PSR4\/5-212 from Kollmorgen to be an optimal solution for enhanced uptime and performance.\u003c\/p\u003e","brand":"Kollmorgen","offers":[{"title":"Unused Surplus","offer_id":52062308041005,"sku":null,"price":2796.75,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52062308073773,"sku":null,"price":2542.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PSR_Servo_Power_Supply_Series__483bc0f9-afc3-4c04-aa43-a69366e2634e.webp?v=1760469389","url":"https:\/\/servosupplier.com\/products\/psr45-212","provider":"Servo Supplier","version":"1.0","type":"link"}
