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 control transformer type designation mean?

The BKC type designation breaks down as follows: "B" stands for Transformer, "K" stands for Control, "C" refers to the C-type core construction, and the trailing number 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 designed for use at altitudes up to 2000 meters above sea level under standard operating conditions. For installations above this altitude, please consult with the manufacturer for special configurations.

Q3: Can BKC series transformers be used in low-temperature environments below -25°C?

Standard BKC series transformers are rated for ambient temperatures down to -25°C. For applications requiring operation below -25°C, a special order must be placed with specific low-temperature requirements clearly stated at the time of ordering.

Q4: What are the key structural advantages of the C-type core used in BKC transformers?

The C-type core is made from high-grade magnetic material, offering reduced energy losses and a compact, space-saving design. The core is secured with strapping for enhanced stability, and the one-piece molded base ensures precise alignment during installation, contributing to a longer service life.

Q5: How should I specify my order for a BKC series control transformer?

When placing an order, please provide the model number (e.g., BKC-150), output capacity in VA, operating frequency (e.g., 50Hz), rated input voltage, and all rated output voltages with their respective capacities. If an isolation shield between the input and output windings is needed, this must also be clearly stated in the order.

Q6: Are BKC series control transformers suitable for outdoor or wet environments?

No. BKC series control transformers must be protected against exposure to water, rain, or snow. They are intended for use in environments free from corrosive gases, dust, and conductive particles. For outdoor or harsh environments, appropriate enclosures or protective housings must be used.
