Export conveying equipment is generally faced with the problem of voltage system mismatch: 220V, 415V, 440V, 480V and other voltage levels are common in the destination national power grid, while the conveyor drive motor and control system are usually designed according to 220V/380V.
When the voltage does not match, the equipment may fail to start, run stuck or even burn down the motor. Voltage deviation exceeding +/-2% will lead to motor speed fluctuation and material conveying dislocation. Long-term undervoltage will also increase the copper loss of the motor by more than 30% and shorten the service life.
Jinma Electric 220V/415V/440V/480V to 220V/380V Isolation Transformer is designed to solve the above problems, convert the multi-country voltage on the input side into 220V/380V required by the equipment, and keep the output stable when the voltage fluctuates.

Isolation Transformers operate based on the principle of electromagnetic induction. The product adopts △/Y connection mode and self-coupling voltage regulation structure. The input side is connected to the power grid voltage within the range of 220V-480V, and the output side is converted to 220V or 380V according to the set transformation ratio.
When the input voltage fluctuates within the range, the voltage regulation link adjusts the output voltage to control the voltage stabilization accuracy within ± 0.5.
It should be noted that this product completes the conversion and stability of the voltage amplitude, does not change the grid frequency, and does not provide backup power supply; the voltage stabilization effect is related to the fluctuation range of the input voltage and the load conditions.
It is suitable for the working conditions of 415V power grid and 380V motor equipment in Europe. After the equipment replacement is completed, the running speed accuracy of the conveyor belt is optimized from 5% to 0.3. The performance is greatly upgraded and successfully passed the acceptance of the German Amazon Logistics Center project.
