Power supplies (transformer type) BP-1



The power supply has several isolated channels (by transformers), LED indication of operation for each channel and electronic protection circuit against overloads and short circuits for each channel.

The power supply is designed to supply a stabilized voltage to various wide-range radio electronic devices, particularly to control and measurement instruments.

BP-1 is designed for maximum output power of 25 W. One-, two-, four- and five-channel designs are available.
This type of power supply is available with three types of enclosure:

  1. in "open" enclosure (bare terminal blocks). Provides protection level IP30.
  2. in "closed" enclosure (terminal blocks are covered). Provides protection level IP 58.
  3. in "closed" enclosure with cable glands. Provides protection level IP65.
