JBK5 Machine Tool Control Transformer

The JBK5 machine tool control transformer is manufactured using imported materials and advanced techniques. It is a high-performance and highly reliable control transformer specially designed for upgrading modern CNC machines, automated production lines, and precision industrial equipment control systems.

Based on the classic JBK series' core safety isolation function, through comprehensive optimization of materials, processes, and design, it aims to provide a purer, more stable, and more intelligent isolation power solution for PLCs, servo drives, touch screens, relays, and safety circuits.

The JBK5 transformer also has the advantages of low energy consumption, small size, and safe wiring. It is the updated product of other machine tool control transformers. It is mainly used in circuits with an input voltage of 50-60Hz and no more than 660V.

Core Advantage

The JBK5 machine control transformer has undergone long-term market testing and has been evaluated by customers as professional, reliable, and safe. This is not due to marketing tactics, but because our Yibaling factory has implemented much stricter requirements than the industry standard.

Our products have set high standards in terms of reliability, safety, anti-interference, and durability. Compared to those products that are only similar in appearance but sacrifice materials and craftsmanship, they stand out particularly.

The key to determining whether a JBK5 machine control transformer can be used for ten years or more is the lifespan of the insulation system: our factory insists on using ≥99.95% pure T2 grade oxygen-free copper enamel wires.

Many low-cost substitutes on the market use copper-clad aluminum wires or recycled copper wires, which have higher resistivity, poorer oxidation and fatigue resistance, and generate more heat during long-term operation, making them potential points of internal aging.

After winding, the coils will enter a vacuum pressure impregnation (VPI) tank. In a vacuum environment, a H-class (180°C) solvent-free epoxy resin paint is used for thorough impregnation and high-temperature curing.

This process turns the coils into a moisture-proof, dust-proof, and vibration-proof whole, capable of resisting the oil mist and moisture erosion commonly found in machine tool workshops. Many low-cost processes only use ordinary dripping or even no impregnation, and the coils are loose, easily affected by the environment.

Between the primary (connected to the power grid) and secondary (connected to the control equipment) windings, our engineers have set up a double barrier.

First, there is enhanced insulation in accordance with international safety standards (such as using three-layer DMD composite insulation paper), ensuring that high voltage will not leak to the low-voltage side.

On top of this, Yibaling also adds a complete copper foil or copper strip shielding layer and ensures its reliable, single-point grounding.

Based on the above solid materials and design, this product is designed to meet the challenges of real workshops:

It can withstand temperature fluctuations, mechanical vibrations, as well as environments with metal dust and oil mist for a long time.

The temperature rise of the JBK5 machine tool control transformer is strictly controlled within the limit allowed by B-class insulation, ensuring that the hot spot temperature does not accelerate insulation aging.

How to Select the JBK5 machine control transformer Model?

1. Clarify the Core Electrical Parameters

List all the equipment powered: PLC modules, servo drive control power supply, relay coils, contactors, indicator lights, safety curtains, lighting lamps, etc.

Add up the VA values of all the loads powered. Make sure to multiply by a safety factor (usually 1.2 to 1.5) to account for transient surges, future capacity expansion, and the transformer's own losses. The final value is the minimum rated capacity of the required transformer (such as 500VA, 1KVA, 2KVA).

2. Evaluate Key Performance

Key Questions: Does your machine use a large number of frequency converters and servo drives? Has the control system ever been interfered with and caused false alarms?

Decision: If the answer is "Yes", then you must choose the JBK5 machine control transformer model with a "Faraday Shield" (shielding layer). This shielding layer can effectively block high-frequency common-mode noise and is crucial for ensuring the stability of the numerical control system.

Key Questions: Where will the transformer be installed? Is the electrical cabinet clean and dry? Is there oil mist, cooling liquid splashing or metal dust?

Decision:

Standard Environment: Choose IP00 or IP20 protection grades (without enclosure or ordinary protection).

Presence of Dust, Slight Oil Mist: Must choose the fully enclosed enclosure JBK5 machine control transformer, with a protection grade of at least IP44.

3. Determine if There is a Special Configuration

Custom Requirements: Do you need multiple independent outputs, special input voltage taps (such as adapting to 380V/400V/415V) or special terminal blocks? Be sure to clearly state this during the selection process.
