Manufactured by \u003cstrong\u003eKollmorgen\u003c\/strong\u003e, this power supply supports up to \u003cstrong\u003e6 BDS4s or BDS5s\u003c\/strong\u003e and operates on an input voltage range of \u003cstrong\u003e90\t6280 VAC\u003c\/strong\u003e with a \u003cstrong\u003emaximum main power input current of 75 Amps RMS\u003c\/strong\u003e. Designed for industrial environments, the unit requires a \u003cstrong\u003ewire gauge for power bus of 8 AWG or larger\u003c\/strong\u003e and accommodates \u003cstrong\u003econnector wire sizes of 22\t618 AWG for signal and control and 16 AWG for power\u003c\/strong\u003e. Factory configured for \u003cstrong\u003eRS-232 \u0026amp; RS-485 communication protocols\u003c\/strong\u003e, the PSR4\/5A-275 ensures seamless integration with standard automation networks.\u003c\/p\u003e\n\n\u003cp\u003eTechnical performance is enhanced through an integrated \u003cstrong\u003eSchaffner Model No. 258-75\/34 filter\u003c\/strong\u003e, mitigating line disturbances and ensuring power quality. The supply employs \u003cstrong\u003eU.L. rated time delay fuses (e.g., BUSS FRN-R series)\u003c\/strong\u003e on the main power input and includes a \u003cstrong\u003ethermal overload relay\u003c\/strong\u003e within the regen resistor kit to protect against sustained overloads. Grounding integrity is maintained with \u003cstrong\u003e20 in\/lb torque for ground studs\u003c\/strong\u003e, while \u003cstrong\u003eterminal torque of 20 in\/lb for main power and bus connection\u003c\/strong\u003e secures reliable electrical interfaces. Flexible installation is afforded by \u003cstrong\u003ecable length increments available from 3 to 75 meters in 3-meter steps\u003c\/strong\u003e, and the design mandates \u003cstrong\u003etwisted cables\u003c\/strong\u003e for AC line specification to minimize EMI.\u003c\/p\u003e\n\n\u003cp\u003eOperational efficiency stems from the PSR4\/5A-275's optimized thermal management and compact footprint. The unit's low overall \u003cstrong\u003eheat dissipation\u003c\/strong\u003e profile reduces cabinet cooling requirements, while the stable DC output supports high-dynamic servo performance. Recommended use of \u003cstrong\u003e600 VAC insulated copper wires\u003c\/strong\u003e enhances system safety and meets industry wiring standards. With support for \u003cstrong\u003eaxis configuration up to six axes with BD5s\u003c\/strong\u003e, the power supply delivers consistent energy regulation across multi-axis drives, enabling synchronized motion and high-precision control.\u003c\/p\u003e\n\n\u003cp\u003eEngineers will appreciate the versatile integration options enabled by the PSR4\/5A-275's adherence to ISO and IEC power system guidelines. The module seamlessly interfaces with Kollmorgen BDS drives and higher-level controllers via \u003cstrong\u003eRS-232\/RS-485\u003c\/strong\u003e, facilitating centralized monitoring and diagnostics. Ideal for packaging machinery, robotic gantry systems, CNC automation, and process control applications, this power supply underpins scalable architectures and ensures high system uptime. Its combination of robust protections, flexible wiring accommodations, and broad compatibility make the PSR4\/5A-275 a cornerstone component in advanced servo installations.\u003c\/p\u003e","brand":"Kollmorgen","offers":[{"title":"Refurbished","offer_id":51690176545069,"sku":null,"price":2791.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PSR_Servo_Power_Supply_Series__cf4814ae-c29b-474a-b046-21d2da0dde6c.webp?v=1760384141","url":"https:\/\/servosupplier.com\/products\/psr45a-275","provider":"Servo Supplier","version":"1.0","type":"link"}
