Power supply units

Scope of application and purpose

The mine power supply unit is designed as a power supply for an automation device or a starter/control station power terminal status output device. The power supply unit may be used at underground excavations at mines, including salt mines, with fresh air inflow ventilation by general mine depression where standard mining electrical equipment of insulation class 2 may be used.

Scope of application and purpose

The explosion-proof power supply unit for mining equipment shall be used as a power supply for automatics devices.

The power supply unit may be used at underground mines and shafts, including salt mines, in the ambient of gas (methane) or dust hazard.

Scope of application and purpose

BPR-07 power supply unit for mining equipment is a power supply for charging simultaneously three or six max. 1000Ah No-Cd and/or Ni-MH batteries used in SL machine panels. The batteries are charged automatically, with pre-discharge followed by charging in order to perform a full duty cycle so as to extend the battery life. The power supply unit may be used at underground excavations at mines, including salt mines, with fresh air inflow ventilation by general mine depression where standard mining electrical equipment of insulation class 2 may be used.
