The mine explosion-proof and intrinsically safe DC stabilized power supply is mainly suitable for working places such as underground coal mines,open-pit coal mines,tunnel pipe corridors,etc.,where there is a danger of gas and coal dust explosions.It is mainly used to provide AC voltage to underground equipment.When the grid voltage is cut off,the power box can automatically switch to the battery to work and continue to supply power to the substation.
Star explosion-proof KDW127/18B explosion-proof and intrinsically safe DC is designed to provide DC18V power supply for explosion-proof and intrinsically safe electrical equipment in coal mines.It supports two voltage inputs,has various installation forms,is convenient to move,and has high-power output.,The voltage is stable,and the ripple is small.The built-in battery in the rated working state can continuously supply power for more than 4 hours,meeting the power supply requirements of underground intrinsically safe equipment.With overload,overvoltage,and overcurrent protection functions.After the fault condition is restored,it will automatically resume work.
Features
1.Strong load capacity:more than 95%of the rated output current,high power utilization
2.Large capacity and longer lasting:using 90VA large capacity lithium manganate battery pack,sustainable power supply for more than 4 hours
3.AC and DC seamless switching:no voltage drop or fluctuation during the switching process
4.Multiple protection circuits such as overload,over current,over voltage,etc.
Explosion-proof and intrinsically safe DC stabilized power supply is compatible with a wide range,and supports all kinds of mining equipment for power supply.
1.Mine explosion-proof power supplies can be widely used in coal mines,gold mines,silver mines,copper mines,iron mines,lead-zinc mines and other underground mines.
2.It can be applied to places with explosion-proof requirements,such as mine tunnels,mine working faces,chemical plants,oil refineries,etc.
3.It can operate normally in places with explosion hazard such as gas,coal dust,dust,high-explosive gas,etc.
