People Electric · Control Transformer
Product overview
People Electric BK transformers supply low-voltage control and auxiliary circuits in machine tools and other mechanical equipment. The original BK table lists 220V or 380V primary options and several secondary-voltage options at each documented capacity. State the winding arrangement and individual secondary-load requirements before ordering; listed alternatives do not mean every voltage is supplied simultaneously.

Specify required primary voltage, secondary voltage, winding/tap arrangement and each secondary load. Capacity is expressed in VA, not watts. BK-2500 appears only in the dimension table and is not offered by these selectors because the rating table does not list it. The complete original PDF is retained.
Typical applications
- Machine-tool control-circuit power supplies.
- Local lighting and indication circuits in mechanical equipment.
