This unit supports \u003cstrong\u003esingle-phase or three-phase AC inputs\u003c\/strong\u003e operating at \u003cstrong\u003e200–240 VAC\u003c\/strong\u003e and delivers a continuous \u003cstrong\u003e15 A capacity\u003c\/strong\u003e to drive high-performance servomotors. It incorporates an \u003cstrong\u003eIGBT-based sinusoidal PWM control system\u003c\/strong\u003e to ensure smooth torque delivery and minimal acoustic noise. Built into a \u003cstrong\u003estainless steel housing\u003c\/strong\u003e, the PRS-1972B provides exceptional durability and corrosion resistance in harsh factory environments. Engineered for precision, this amplifier is a key component in multi-axis systems requiring consistent, repeatable motion control.\u003c\/p\u003e\n\n\u003cp\u003eFeaturing advanced control technology, the PRS-1972B integrates \u003cstrong\u003epre-installed regenerative resistors\u003c\/strong\u003e to recover braking energy and improve overall efficiency. Its support for \u003cstrong\u003eoptical incremental encoders\u003c\/strong\u003e allows for feedback at \u003cstrong\u003e1000 or 2500 pulses per revolution\u003c\/strong\u003e, enabling fine resolution and accurate position tracking. The built-in \u003cstrong\u003eencoder signal filtering\u003c\/strong\u003e function optimizes noise immunity and ensures stable closed-loop performance. With a front-end capable of accepting \u003cstrong\u003esingle- or three-phase 200–240 VAC\u003c\/strong\u003e, the amplifier maintains a high power factor and reduces harmonics on the supply network. Additional surge and overcurrent protection circuits safeguard both amplifier and motor against electrical faults.\u003c\/p\u003e\n\n\u003cp\u003eOperationally, the PRS-1972B excels under demanding conditions. It remains fully functional at ambient temperatures between \u003cstrong\u003e0 °C and +55 °C\u003c\/strong\u003e and can be stored safely from \u003cstrong\u003e–20 °C to +65 °C\u003c\/strong\u003e without degradation. The design tolerates \u003cstrong\u003erelative humidity up to 90% RH\u003c\/strong\u003e (non-condensing) and is rated for reliable operation up to \u003cstrong\u003e1000 m elevation\u003c\/strong\u003e, accommodating diverse installation sites. Mechanical resilience is assured with \u003cstrong\u003evibration resistance of 4.9 m\/s²\u003c\/strong\u003e and \u003cstrong\u003eshock resistance of 19.6 m\/s²\u003c\/strong\u003e, making it ideal for mobile platforms or heavy machinery. Clear \u003cstrong\u003efront-panel indicator lights\u003c\/strong\u003e provide real-time status monitoring, simplifying troubleshooting and preventive maintenance.\u003c\/p\u003e\n\n\u003cp\u003eIntegration into control architectures is straightforward: the PRS-1972B fits on \u003cstrong\u003eDIN rails or custom brackets\u003c\/strong\u003e, matching standard rack layouts for multi-axis systems. Its compatible interface supports industry-standard encoder signals and drive bus communications, facilitating seamless connection with PLCs and motion controllers. Applications span CNC machinery, robotic arms, packaging lines, and textile equipment where precise velocity and torque control are critical. By combining energy recovery, high-resolution feedback, and rugged construction, the PRS-1972B stands as a versatile and reliable choice for complex automation projects.\u003c\/p\u003e","brand":"Sanyo Denki","offers":[{"title":"Refurbished","offer_id":51689835168045,"sku":null,"price":1128.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/PRS_Servo_Drive_Boards__8e096d8f-1f28-408f-a33a-da155d1279e7.webp?v=1760382819","url":"https:\/\/servosupplier.com\/products\/prs-1972b","provider":"Servo Supplier","version":"1.0","type":"link"}
