BK Industrial Control Transformers

CJ’s TB Series Industrial Control Transformers are especially designed to accommodate the momentary current inrush caused when electromagnetic components are energized... without sacrificing secondary voltage stability beyond practical limits. The transformer’s windings and internal terminations are encapsulant encased in a durable thermoplastic end cap, protecting them from potentially damaging moisture, dirt and other ambient contaminants. CJ’s TB Series transformers are dry-type, step-down transformers with the secondary control circuit isolated from the primary line circuit to assure maximum safety.

Voltage regulation of CJ’s TB Series transformers exceeds standards recommended by the National Electrical Manufacturers Association. Secondary circuit voltage drop between no-load and momentary overload remains exceptionally low. This excellent secondary circuit voltage regulation assures reliable operation of electromagnetic components and may permit the use of a smaller  and less expensive industrial control transformer.

BK Industrial Control Transformers Details

Scope of Application

BK Industrial Control Transformer is suitable for the AC circuit of 50Hz/60Hz, which is used as the control power, local lighting and indicator light power supply for general electrical apparatus in machine tools and machinery.

The Industrial Control Transformer meets the standard: JB/T9646 standard.

Normal working conditions and installation conditions

The Industrial Control Transformer can work reliably under the following environmental conditions.

The altitude does not exceed 2000m.

The ambient air temperature upper limit is 40°C, and the lower limit is -5°C. (When the user needs to use it in the environment higher than 40°C or lower than -5°C, special instructions and special custom are required when ordering.)

When the max temperature is 40°C, the relative humidity of the air does not exceed 50%. At relatively low temperatures, higher relative humidity may be allowed, for example, 90% at 20°C. Special measures should be taken for the occasional condensation produced due to temperature changes.

In the ambient air, there is no no corrosive metal or harmful gas or dust that destroys insulation; In the use, Industrial Control Transformers must not be corroded by water, rain, or snow.

The power supply voltage is similar to the sine wave.
