Model
KDW26 Mine-used Stabilized Power Supply is a molded power supply
of Intrinsic Safety output (m[ib]I) and is designed according
to MT/T409-1995 Mine-used DC Stabilized Power Supply.
It
is suitable for the coal mine underground to supply power for
the Intrinsic Safety camera or the sensors of mine production
and safety monitoring and control system.
Cable Lead-in Mode: 1) The power supply has a 3m mine-used rubber cable
at the input side of AC127V/220V, and the cable is cemented
with the power body as a whole;
2) The intrinsic safety output has connection terminals for
cables to connect with intrinsic safety devices;
3) According to the above cable lead-in mode, the power supply
is placed near the power-feeding switch, not near the intrinsic
safety devices.
