Product Details

Single phase rectifier DC transformer is a rectifier equipment composed of AC transformer and rectifier elements to obtain DC power from AC power supply. Rectifier equipment is a DC power supply commonly used in modern industrial enterprises. The principle of rectifier DC transformer is the same as that of ordinary transformer. Transformer is a kind of equipment for converting AC voltage based on the principle of electromagnetic induction. The transformer generally has two independent windings, the primary winding and the secondary winding, which share an iron core. The primary winding of the transformer is connected to the AC power supply, and the alternating current flows through the winding to generate the magnetic potential, so there is alternating magnetic flux in the closed iron core. The primary and secondary windings cut the magnetic lines of force, and the AC with the same frequency can be induced in the secondary. Then the rectifier module is installed at the secondary end to obtain the DC voltage. The turns ratio of the primary and secondary windings of the transformer is equal to the voltage ratio.

Ambient air temperature:

1. The upper limit of ambient air temperature shall not exceed + 40 ℃;

2. The average value of ambient air temperature for 24h shall not exceed + 30 ℃;

3. The lower limit of ambient air temperature shall not be lower than - 5 ℃;

Atmospheric conditions:

The relative humidity of the atmosphere shall not exceed 50% when the ambient air temperature is + 40 ℃, and it can have higher relative humidity at lower temperature. The average maximum relative humidity in the wettest month is 90%, and the average minimum temperature in that month is + 25 ℃, taking into account the condensation on the product surface due to temperature change;

Pollution level: the pollution level is level III;

Installation category: (overvoltage category) installation category is class III;

Power supply voltage: the allowable deviation of power supply voltage is ± 5%;

Installation conditions: it shall be installed where there is no violent vibration and no medium shock vibration.

1. Rectifier DC transformer is composed of transformer and rectifier device. The use of rectifier transformer must meet the conditions specified in Article 2; Carefully check the parameters on the nameplate before installation

2. After confirmation, it can be installed and used;, Connect the wire according to the standard, and power on after checking that there is no error

3. Avoid collision as much as possible during transportation and store in a dry and ventilated place without moisture, so as to ensure the performance and service life of the product.

 

Product quality assurance and service guarantee of the company:

Before leaving the factory, each product is fully inspected in strict accordance with the national standard to ensure that the factory pass rate is 100%, and all products are guaranteed for one year( (except for special customer requirements)

It is widely used in DC transmission, mechanical and electronic equipment, lighting, rectifier, electrochemical industry, armature, battery charging, electrostatic dust removal, power transmission, generator excitation, electric traction, steel rolling, electroplating, electrolysis and other fields.
