Operating on a standard 120 VAC single-phase input, this drive converts alternating current into a highly controlled 0-90 VDC adjustable output. By delivering smooth, variable power, the controller enhances operational efficiency, extends mechanical component lifespan, and optimizes motor performance in light industrial and OEM automation applications.\u003c\/p\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable height=\"374\" style=\"width: 89.1509%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eCondition\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eNew\/Never Used Surplus\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eBrand\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eDanfoss (Graham Transmissions)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eCategory\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eMotor Controls\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003ePart Number\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003e176B1111\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eSubcategory\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eDC Motor Drives\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eProduct Series\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eVari Speed S1000\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eInput Voltage\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003e120 VAC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eOutput Voltage\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003e0-90 VDC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003ePhase\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003e1-Phase\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eSupported Motor HP\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003e1\/20 to 2 HP\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eOutput Control\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eAdjustable ACCEL and DECEL\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eComponent Architecture\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003eSolid-State (NEMA Code K)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 44.9207%;\"\u003e\u003cspan\u003e\u003cb\u003eWeight\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 54.7471%;\"\u003e\u003cspan\u003e2.0 lbs\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eInformation About \u003cspan\u003e176B1111\u003c\/span\u003e\u003cspanmarket data-sheets-root=\"1\"\u003eBCM-MS\/TP\u003c\/spanmarket\u003e\n\u003c\/h4\u003e\n\u003cp\u003eThe 176B1111 is a core module belonging to the reliable Vari Speed S1000 series, originally developed by Graham Transmissions and supported under the Danfoss industrial portfolio. It utilizes advanced surface-mount component technology to pack robust motor control capabilities into an exceptionally small open-chassis footprint. Automation technicians and machine builders deploy this NEMA Code K converter—featuring two silicon-controlled rectifiers (SCRs), two diodes, and a freewheeling diode—to ensure an excellent form factor and consistent electrical delivery to the motor armature. The unit features built-in, adjustable acceleration (ACCEL) and deceleration (DECEL) potentiometers directly on the printed circuit board, allowing operators to seamlessly fine-tune motor ramp times for delicate manufacturing processes or heavy starting loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e● Solid-State Conversion: Reliably converts standard single-phase 120 VAC line power into an adjustable 0-90 VDC output to drive industrial DC motors efficiently.\u003cbr\u003e● Adjustable Ramp Rates: Features integrated on-board rotary potentiometers for the precise calibration of motor acceleration and deceleration timing.\u003cbr\u003e● Surface-Mount Technology: Utilizes advanced electronic manufacturing processes to ensure high vibration resistance, long-term electrical reliability, and a minimal footprint.\u003cbr\u003e● NEMA Code K Architecture: Employs a robust bridge rectifier configuration to deliver a smooth voltage form factor and prevent excessive motor heating.\u003cbr\u003e● Broad Motor Support: Engineered to control a wide range of light-industrial DC motors from 1\/20 HP up to 2 HP, providing flexible application potential.\u003cbr\u003e● Space-Saving Layout: Designed with a miniature, open-chassis board structure that allows for rapid integration into crowded electrical panels and OEM machinery.\u003cbr\u003eThe 176B1111 delivers the reliability and precise speed regulation required for continuous, efficient DC motor operation in demanding production environments.\u003c\/p\u003e\n\u003cp id=\"p-rc_c7b8f4fae39e183e-25\"\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Danfoss","offers":[{"title":"Default Title","offer_id":52614413844778,"sku":"176B1111","price":1515.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1600_895f67d7-89b5-46ca-a14b-09d9525981af.webp?v=1789503353","url":"https:\/\/iqelectro.com\/products\/danfoss-176b1111-vari-speed-s1000-120vac-to-90vdc-motor-speed-controller","provider":"IQElectro","version":"1.0","type":"link"}
