This device provides an \u003cstrong\u003eadjustable output voltage\u003c\/strong\u003e and an \u003cstrong\u003eoutput current of 75 A\u003c\/strong\u003e to meet the demands of modern servo-driven systems. Rated for \u003cstrong\u003e21 kW output power\u003c\/strong\u003e, it operates reliably at a \u003cstrong\u003efrequency of 50-60 Hz\u003c\/strong\u003e while maintaining stability under variable load conditions. Housed within an \u003cstrong\u003eIP20 enclosure\u003c\/strong\u003e, the unit offers built-in \u003cstrong\u003eoverload protection\u003c\/strong\u003e, \u003cstrong\u003eovervoltage protection\u003c\/strong\u003e, and \u003cstrong\u003eshort circuit protection\u003c\/strong\u003e to safeguard connected components. Compact and purpose-built, the PSR3-230\/75-21-202 excels in delivering uninterrupted power in space-constrained industrial cabinets.\u003c\/p\u003e\n\n\u003cp\u003eDetailed technical specifications define the PSR3-230\/75-21-202’s operational envelope. The unit accepts an \u003cstrong\u003einput voltage of 230 V AC\u003c\/strong\u003e and produces an \u003cstrong\u003eadjustable output voltage\u003c\/strong\u003e range tailored to specific servo drive requirements. It sustains a continuous \u003cstrong\u003eoutput current of 75 A\u003c\/strong\u003e and achieves \u003cstrong\u003e21 kW output power\u003c\/strong\u003e without degradation in performance. The internal PCB features precision components dedicated to \u003cstrong\u003ecurrent regulation\u003c\/strong\u003e, ensuring tight control of voltage ripple and load transients. The IP20-rated housing provides ingress protection against solid objects, and its compact form factor simplifies mounting within standard industrial racks.\u003c\/p\u003e\n\n\u003cp\u003eOperational performance is optimized for reliability and ease of maintenance. The PSR3-230\/75-21-202 requires \u003cstrong\u003eupright installation only\u003c\/strong\u003e to ensure adequate heat dissipation, as its heatsink and airflow pathways are oriented for vertical mounting. Thermal management is further enhanced by the design of the internal PCB and enclosure, allowing continuous operation at full load without derating. Multiple safety interlocks and status indicators simplify troubleshooting by clearly reporting fault conditions, while the option to connect an \u003cstrong\u003eexternal resistor\u003c\/strong\u003e enables flexible braking energy dissipation. Maintenance intervals are extended thanks to the durable construction and the absence of moving parts, reducing system downtime.\u003c\/p\u003e\n\n\u003cp\u003eIntegration into motion control architectures is straightforward, leveraging standardized interfaces and the consistent performance profile of the \u003cstrong\u003ePSR Servo Power Supplies\u003c\/strong\u003e series. The PSR3-230\/75-21-202 seamlessly pairs with Kollmorgen servomotors and drives, maximizing system reliability and simplifying engineering workflows. Its modular design supports rapid replacement or upgrade, making it ideal for applications in robotics, CNC machining centers, packaging machinery, and general industrial automation tasks where power stability and safety are critical.\u003c\/p\u003e","brand":"Kollmorgen","offers":[{"title":"Refurbished","offer_id":52067423846701,"sku":null,"price":6439.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PSR_Servo_Power_Supply_Series__1b308551-5812-4e53-a113-1a0f58b01ca1.webp?v=1760384187","url":"https:\/\/servosupplier.com\/products\/psr3-23075-21-202","provider":"Servo Supplier","version":"1.0","type":"link"}
