BK single-phase control transformer parameter table

Understanding BK Single-Phase Control Transformer Parameters

When selecting a BK single-phase control transformer,380V DC power supply manufacturer understanding its key parameters is crucial for proper system integration. These compact transformers are widely used in industrial control circuits, machine tools, and automation equipment where voltage regulation and isolation are required.

Key Parameters in the Specification Table

A typical BK transformer parameter table includes these essential specifications:

• Input voltage: Usually 220V or 380V variants
• Output voltage: Ranging from 6V to 220V in standard models
• Rated capacity: Expressed in VA (volt-ampere)
• Frequency: Typically 50Hz/60Hz
• Insulation class: Class B or higher for industrial applications

How to Choose the Right BK Transformer?

Selecting the proper control transformer involves more than just matching voltage ratings. At China Hongye Electric, our engineers recommend considering these factors:

Load Characteristics Matter

The transformer's VA rating should exceed your actual load by at least 20% margin. For equipment with high inrush currents (like contactors or solenoids), this buffer should be increased to 30-50%. Our factory-direct transformers use pure copper windings and high-grade silicon steel to handle such demands reliably.

One common question we hear is: "What if my application requires non-standard voltages?" This is where China Hongye Electric's customization capability shines. We can manufacture BK transformers with special voltage combinations while maintaining the same rigorous factory testing as standard models.

Installation and Maintenance Best Practices

Proper installation extends transformer lifespan significantly. Follow these guidelines:

• Mount in well-ventilated areas away from heat sources
• Maintain at least 50mm clearance around ventilation openings
• Check terminal tightness during annual maintenance

At China Hongye Electric, every BK transformer undergoes comprehensive testing including:

1. Dielectric strength test (3500V for 1 minute)
2. Load test at 110% rated capacity
3. Temperature rise verification

This stringent quality control explains why we confidently offer a 3-year warranty on all our control transformers.

Frequently Asked Questions

Can BK transformers be used with variable frequency drives?

While possible, we recommend consulting our engineers for such applications. The harmonic content in VFD outputs may require special consideration in transformer design.

What's the typical lead time for custom BK transformers?

Standard models ship within 3-5 days, while custom configurations typically require 7-10 days from China Hongye Electric's dedicated production line.

With 20 years of transformer manufacturing experience and serving over 10,000 industrial clients, we've refined our BK series to meet diverse control circuit needs. Our complete product range includes 9 major series with 54 product categories, ensuring you find the perfect match for your application.
