Product Overview
The BK series is a control-transformer range for electrical control circuits. The current product data lists 50–2500 VA capacity, AC 220/380 V input, customizable AC 6–220 V output, and 50/60 Hz frequency. Select the model from the actual control load and installation requirements rather than from the unrelated R-series dimensional data previously shown on this page.

Selection Guidance
Determine the required VA capacity from the connected control load and expected duty. Confirm input voltage, every required secondary voltage, frequency, insulation class, mounting method, terminal arrangement, enclosure protection, ambient conditions, and available panel space. Request the BK-series outline drawing for the selected rating before finalizing the cabinet layout.
Frequently Asked Questions
What capacity range is listed for the BK series?
The listed range is 50–2500 VA. The selected rating must cover the connected control load and applicable design margin.
What voltage options are listed?
Input is listed as AC 220 V or 380 V. Output is listed as customizable within AC 6–220 V.
Can the BK series be mounted on a panel or DIN rail?
Both panel and DIN-rail mounting are listed. Confirm the mounting arrangement and dimensions for the selected rating.
Why is the previous dimension table not included?
The previous table used R-series model names, so those dimensions cannot be treated as verified BK-series dimensions.
What should be provided for a quotation?
Provide capacity, input and secondary voltages, frequency, mounting method, terminal requirements, dimensions, quantity, and destination.
