Eaton Crouse-Hinds VMV3LL/UNV1 LED Luminaire Unit

Module Feature

VMV3LL/UNV1 belongs to Eaton Crouse-Hinds Champ VMV series hazardous area LED high bay luminaire. Rated output 3531 lumens at 29W power consumption, luminous efficiency 122 lm/W, equivalent to traditional 70–100W HID lamp. Universal wide voltage design supports 120-277VAC and 108-250VDC input. Type V wide light distribution lens, heat and impact resistant tempered glass window. Die cast aluminum housing with corrosion resistant coating, NEMA4X rating for dust and water splash protection. Certified for Class I Div 2, Class II Div 2 hazardous classified environments. Long service life LED array, low maintenance requirement. Widely used for chemical plants, grain handling facilities, paint mixing rooms and industrial high bay hazardous site lighting.

Working principle

Built-in LED driver converts universal AC/DC input voltage into constant low-voltage DC power for LED array. LED chips produce white illumination, light beam redistributed through precision optical lens to achieve Type V wide area lighting distribution. Aluminum housing conducts and dissipates heat generated by LED module to maintain stable operating temperature and extend service life.

Onboard components

Die cast aluminum luminaire housing, constant current LED driver, LED light array, tempered glass lens, silicone sealing gasket, slipfitter mounting interface, internal wiring terminal block.

LED indicators

No built-in diagnostic LED indicators.

Hardware self-diagnosis

Visual inspection of glass lens for crack or contamination, check housing corrosion and gasket aging, measure input voltage, inspect LED driver abnormal heating.

Programming software

No dedicated programming software.
