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 (FAQ)

1. What does the "C" stand for in the BKC series designation?

The "C" designates that the transformer is built with a high-grade C-type core, ensuring compact dimensions, low core losses, and optimized magnetic efficiency.

2. Can the BKC series transformer operate at temperatures below -25°C?

The standard operational temperature range is -25°C to +40°C. If applications require operation below -25°C, a customized special order is required to meet specific environmental needs.

3. Is an isolation shield between input and output windings standard?

An electrostatic isolation shield is an optional configuration. If your circuit requires additional electrical isolation and noise suppression, please specify this requirement when placing your order.

4. Can I configure multiple output voltages on a single transformer?

Yes, multiple output voltages and divided power capacities can be customized (e.g., specifying both 110V and 24V secondary taps with individual VA distribution).

5. What environmental protections are required during installation?

The unit must be placed in an environment free of conductive dust, corrosive gases, water, rain, or snow, with relative humidity below 95% and an altitude no higher than 2000 meters.
