In a 238.1 mm (9.38 in) long, 185.6 mm (7.3 in) wide, 152.4 mm (6 in) high chassis weighing 6.4 kg (14 lb), the unit supports a peak power dissipation of 1000 W and a continuous dissipation of 250 W. The amplifier section provides 2 A per volt of input gain, a bandwidth of 500 Hz, and a peak power output of 500 W with 160 W continuous, along with a 2 A current limit and a 1 A shutdown threshold. Open‑loop voltage gain is specified at 100 dB, with drift of 10 µV\/°C and an offset adjustable to zero. Operating temperature is 0 to 50°C (derating 2.0 W\/°C above 25°C); storage temperature ranges from −30 to 80°C. The device requires a control closure capable of handling 20 mA for proper shutdown behavior and has a 3AG slow‑blow fuse typical of its protection scheme. These specifications position the 4020‑LS as a high‑performance linear servo amplifier for DC motor control in demanding motion systems. \u003c\/p\u003e\u003c\/div\u003e","brand":"Aerotech","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657055863086,"sku":null,"price":580.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3dabd88f-abc7-47f6-b111-0973f1d5101e.jpg?v=1769465632","url":"https:\/\/plgautomation.com\/products\/aerotech-4020-ls-linear-servo-amplifier","provider":"PLG Automation ","version":"1.0","type":"link"}
