Ordering Information

When ordering the control transformer model BKC-150, please provide the following specifications: output capacity 150VA, frequency 50Hz, rated input voltage 220V, and rated output voltages with their respective capacities—110V (100VA) and 24V (50VA). If an isolation shield between the input and output windings is required, please clearly note this in your order.

Frequently Asked Questions

Q1: What does the BKC series designation stand for?

The BKC series designation breaks down as follows: "B" stands for Transformer, "K" for Control, "C" for C-type core, and the number that follows indicates the rated capacity in VA (volt-amperes).

Q2: What is the maximum operating altitude for BKC series control transformers?

BKC series control transformers are rated for a maximum operating altitude of 2000 meters. For installations above this altitude, please consult the manufacturer for special configurations.

Q3: Can BKC control transformers be used in environments with temperatures below -25°C?

Standard BKC transformers are designed for ambient temperatures from -25°C to +40°C. For applications requiring operation below -25°C, a special order must be placed with the appropriate specifications clearly stated.

Q4: What are the key structural advantages of the BKC series?

The BKC series features a C-type core made from high-grade magnetic material, a compact one-piece molded base for precise alignment, strapping-secured core for stability, and terminal blocks designed for safe and straightforward wiring—making it suitable for continuous industrial operation.

Q5: What information is needed when placing an order for a BKC control transformer?

When ordering, you should specify the model (e.g., BKC-150), total output capacity (VA), frequency (Hz), rated input voltage, and the rated output voltages with their respective capacities. If an isolation shield between input and output windings is needed, this must also be noted in the order.

Q6: Are BKC series transformers suitable for outdoor installation?

No. BKC series control transformers must be protected against exposure to water, rain, or snow. They are designed for indoor or sheltered installations only. The environment should also be free from corrosive gases, dust, and conductive particles.
