SVEL-11 energy saving explosion-proof fluorescent light

Environment conditions:

  • Underground and ground premises of mines, pits with the ambient of hazardous gas and/or combustible dust

  • Category I explosive mixture (methane at underground works) ambient or corrosive salty dust ambient

  • UKhL (temperate and cold) climatic version, location category 5

  • Ambient temperature: minus 10°C to +35°C

  • Relative humidity: (98±2)% at (35±2)°C

  • Installation site vibration: max. 25Hz, acceleration at max. 1g

  • Working position: not limited

  • Allowable power mains voltage fluctuations: 80% to 115% of rated value

  • Dust concentration in air: max. 1200 mg/m3

Additional functions:

  • Emergency stop of the mining equipment by triggering the standard emergency switch

  • Power supply remote control

  • Ground wire integrity check, lighting circuit fault search and localization

The lights shall be powered by insulated-neutral AC mains. The lighting circuit power supply shall feature a diode-controlled intrinsically safe remote control and monitoring circuit of at least ib rating.
