BK Control Transformer

Ningbo Chuangbiao Electronic Technology Co., Ltd. has been building electronic transformers since 2010, and over the years we've grown into one of the go-to names for control transformers. We put all our focus on R&D and production, and our BK series has become the real standout — it's the one we designed specifically for industrial automation and power control setups. It shows exactly what we've learned in over a decade of making these things.

The BK transformer uses a solid EI core with tight manufacturing and good materials, so it delivers clean, efficient power no matter how the load swings. You get higher magnetic flux, way less energy waste, and a compact size that still keeps the output voltage rock-steady. The electrical isolation is excellent too — it shuts out voltage spikes, electromagnetic noise, and all the interference you run into in busy factories. That's huge when you're running sensitive controls.

Load regulation is another area where it shines. Even when machines are starting, stopping, or changing speed like crazy, the voltage stays right where it needs to be. And because we use quality insulation, the whole unit handles high heat and humidity without breaking a sweat. It just keeps running reliably in tough industrial environments, year after year.

We follow ISO 9001 to the letter here. Every BK transformer gets multiple rounds of testing before it leaves the door, so you know it's stable and safe. We're also ROHS certified, which matters to us and to our customers. Our development team averages over seven years of hands-on experience in design, production, and quality — they're the ones who make sure every unit works perfectly and that we can give you real technical support when you need it.

You'll see BK transformers everywhere: PLC control systems, automated production lines, robot controllers, medical equipment, communication setups, and precision instruments. Anywhere you need solid electrical isolation, steady voltage under changing loads, and power you can trust, this is the one that gets the job done.

We've built a good reputation in the industry because we keep the quality high, the prices fair, and the service honest. We're based right by the Hangzhou Bay Bridge in Zhejiang Province. If you're ever in the area, swing by — we'd love to show you around, talk specs, or just chat about how BK transformers can fit into your next project. Looking forward to working together!
