Explosion-proof and Intrinsically Safe DC Regulated Power Supply

The explosion-proof and intrinsically safe DC regulated power supply for mining applications is primarily designed for use in underground coal mines, open-pit coal mines, tunnel utility tunnels, and other workplaces where there is a risk of gas and coal dust explosions. It is mainly used to provide AC voltage to underground equipment. When the grid power fails, this power unit can automatically switch over to battery operation, ensuring continuous power supply to the substations.

The ASTTAR explosion-proof KDW127/18B intrinsically safe and flameproof DC power supply is specifically designed to provide DC 18V power to intrinsically safe and flameproof electrical equipment used underground in coal mines. It supports dual voltage inputs, offers versatile installation options for easy mobility, and delivers high-power output with stable voltage and minimal ripple. In its rated operating mode, the built-in battery ensures continuous power supply for more than 4 hours, fully meeting the power requirements of intrinsically safe devices in underground mining environments. Additionally, the unit features comprehensive protection mechanisms against overload, overvoltage, and overcurrent conditions. Once a fault is resolved, the system automatically resumes normal operation.

Product Features

1. Strong load capability: Delivers more than 95% of the rated output current, resulting in high power efficiency.

2. High Capacity, Longer Lasting: Equipped with a 90VA high-capacity lithium-manganese battery pack, it provides continuous power for over 4 hours.

3. Seamless AC/DC Switching: Ensures no voltage drop or fluctuation during the switching process

4. Multiple protection circuits against overload, overcurrent, overvoltage, and more

Environmental Usage

The explosion-proof and intrinsically safe DC regulated power supply is widely compatible and supports powering various mining equipment.

1. Mine-proof explosion-proof power supplies can be widely used in underground operations of various types of mines, including coal mines, gold mines, silver mines, copper mines, iron mines, lead-zinc mines, and more.

2. It can be applied in areas with explosion-proof requirements, such as mine tunnels, mining workfaces, chemical plants, refineries, and more.

3. It can operate normally in environments where there is a risk of explosion, such as areas with gas, coal dust, airborne particles, or highly explosive gases.
