Explosion-proof lamp DSP52 series low-voltage

*Interpretation of symbols

Designed for use as an individual portable lighting device in explosive zones 1, 2, 21, 22, where, under operating conditions, the formation of explosive mixtures of gases and vapors with air is possible.







Used as a stationary device on fixed or mobile equipment

Explosion-proof lamp of ДСП52 series consists of two, three or more lamps of smaller power connected in parallel with the help of specially designed rigid fasteners, which allow to use one suspension and one input box for the whole modular assembly. Lighting fixtures are arranged at the customer ‘s request.

The special feature of the DSP52-XXn lamp housing design makes it possible to use it on special cars and mechanisms operating under heavy operating conditions in areas where explosive dust or gas mixtures may appear.

Nizhny Novgorod Special Vehicle Center actively uses these lamps.

Additionally, the lamp can be equipped with explosion-proof cable entries for armoured cable or with attachment for metal hose.
DSP52-ХХn in low-voltage version (in AC and DC circuits 12… 48 V) allows to use it as a portable explosion-proof lamp during repair of tanks and oil pipelines, as well as to use it on various mobile rigs, pumps, etc. according to the category of explosion protection.
