{"product_id":"175l3718","title":"175L3718","description":"\u003cp\u003eThe \u003cstrong\u003e175L3718\u003c\/strong\u003e is an AC variable frequency drive engineered by Danfoss for the VLT 3000 Variable Speed Drives series. In an automation cell it converts fixed-frequency three-phase mains power into a controllable output that matches motor demand, allowing speed control without mechanical throttling. The unit forms the interface between the plant’s PLC signals and a 3-phase induction motor, so it governs acceleration, deceleration, and steady-state torque while maintaining line-side power factor. As part of this series, it supports standard cabinet mounting and interacts with fieldbus modules offered by the manufacturer.\u003c\/p\u003e\u003cp\u003eElectrical capacity is defined by a rated output of \u003cstrong\u003e125 HP\u003c\/strong\u003e and a continuous phase current of \u003cstrong\u003e168 A\u003c\/strong\u003e. Within the specified ±10 % line window the converter draws a maximum of 167.2 A and can deliver 185 A for 60 s to cover short overloads. Apparent power peaks at 116 kVA, while conversion efficiency reaches \u003cstrong\u003e0.96\u003c\/strong\u003e at full load so only 4 % of input power is lost as heat. The drive produces output frequencies up to \u003cstrong\u003e120 Hz\u003c\/strong\u003e, letting motors run at double synchronous speed when mechanical limits permit. Acceleration profiles are shaped by a programmable ramp that extends to \u003cstrong\u003e3600 s\u003c\/strong\u003e, and upstream protection is provided by a 250 A pre-fuse coordinated with the semiconductor bridge.\u003c\/p\u003e\u003cp\u003eInstallation factors are addressed by a permitted motor lead length of 1000 ft and an output terminal that accepts conductors up to \u003cstrong\u003e500 kcmil\u003c\/strong\u003e. At maximum loading the inverter dissipates \u003cstrong\u003e910 W\u003c\/strong\u003e, a thermal figure that dictates enclosure airflow when the ambient temperature reaches the series limit of 40 °C. The chassis passed a vibration test of \u003cstrong\u003e0.7 g\u003c\/strong\u003e, supporting placement on machines with moderate dynamic forces, and its transport mass is \u003cstrong\u003e464 lb\u003c\/strong\u003e, which influences cabinet bracing and lift planning. Voltage tolerance remains ±10 % across this range, and the model’s efficiency assists in maintaining stable heat rise during prolonged duty.\u003c\/p\u003e","brand":"Danfoss","offers":[{"title":"Refurbished","offer_id":52105405727021,"sku":null,"price":7175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/175l3718__e2459e0b-fbd5-4bdf-8f2e-d05785d27ffe.webp?v=1771402511","url":"https:\/\/servosupplier.com\/products\/175l3718","provider":"Servo Supplier","version":"1.0","type":"link"}
