With a capacity of 50,000 VA and below, it is suitable for circuits with an input voltage of 1000V and below AC 50-60Hz.

Long-term continuous operation at nominal capacity, are widely used in machine tools and machinery in general electrical power source as a control, local lighting and power indication.

◆ transformer According to capacity、Voltage and use Different requirements，Structures are Have Differences of，Generally divided into two forms of shelled and not shelled。

◆ The transformer coils are all double or multiple windings.I.e., a plurality of taps of the secondary manner Or using multiple windings come To get the voltage and capacity needed for distribution。

◆ Double winding transformer coil，Primary current l1=pe/u1, secondary current l2=pe/u2

◆ The transformer primary, secondary If the winding has a center tap.in this situation，Primary and secondary capacity and current will be allocatedBut the maximum current that the winding is subjected to is fixed.

◆ If multiple windings, one primary winding，The secondary has two separate windings,Capacity of each secondary winding is allocated according to the needs of voltage and current,The sum does not exceed Rated Capacity Basically satisfy Pe = P score 1 + P score 2

◆ BK series transformers are divided into shells according to the structure.Press installation is divided into vertical。

◆The altitude does not exceed 2000 meters;

◆Ambient air temperature -25 degrees to +40 degrees,The average value of 24 hours does not exceed +35 degrees;

◆The relative humidity of the air is not more than 90% when it is +25 degrees.Not more than 50% at +40 degrees;

◆No severe vibration and shock vibration of the place,No severe vibration and shock vibration of the place,

◆In a medium without explosion hazard，No metal corrosion and damage the insulation gas and conductive dust;

When ordering our products, please indicate the following:

◆The basic model specifications, capacity and quantity of the transformer;

◆The primary and secondary voltages of the transformer;

◆When a secondary voltage is supplied,If need to provide respective voltages capacity allocation;

◆If the appearance and installation dimensions in the table do not meet the requirements for use,Please clearly indicate;

If the user has special requirements, the company can design and manufacture on its behalf;
