380v/400v To 208v Variable Frequency Power Supply Exported To Liberia

Liberia

VIEW PROJECT

In Liberia, on the West African coast, industrial development and infrastructure development are accelerating. However, there is a realistic threshold between the US standard 208V power grid used in some areas and the 380V/400V industrial voltage commonly used in the world: motors, pumps and processing machines designed for 380V/400V are directly connected to 208V, which is often difficult to start; Even if it barely operates, it is still in a state of undervoltage for a long time, with reduced efficiency, increased heating and significantly shortened equipment life.

415V to 380V Isolation Transformer Export Malaysia

Malaysia

VIEW PROJECT

An automated packaging line shipped from China to Penang factory in Malaysia, after power-on, the inverter frequently alarms, the servo motor abnormally heats up, and the PLC control module restarts without reason. The engineer checked all the mechanical and program parameters, everything was normal, and finally the multimeter revealed the truth: the workshop distribution voltage measured 425V, and the equipment nameplate clearly said "three-phase 380V".

300KVA Three-Phase Compensated Regulator Export Thailand Hardware Factory

Thailand

VIEW PROJECT

Many industrial parks in Thailand, especially the hardware processing plants in 2 third-tier cities, generally have the power supply problem of long-term low incoming line voltage. The pressure of the punch cannot meet the process requirements, the motor frequently heats up, and the numerical control system stops the alarm without reason. , these problems seem to be scattered, and the root is often only one. " not enough voltage ".

GOT A QUESTION?

Frequently Asked Questions

Can you customize transformers for different input and output voltages?

Yes. We support customized voltage configurations such as 480V to 380V, 600V to 380V, 415V to 380V, 400V to 220V and many other combinations based on your local grid and equipment requirements.

What certifications and standards can your products support?

Depending on the product and project requirements, solutions can be developed around applicable UL, CSA and TUV/CE requirements. Please contact us to confirm the certification scope required for your specific model and market.

Can you manufacture transformers for the U.S., Canada and other international markets?

Yes. We provide power solutions for different international voltage systems, including 480V applications in the U.S., 600V applications in Canada, and other customized configurations for Europe, Southeast Asia and global markets.

What is the typical production lead time?

Lead time depends on product type, capacity, customization, quantity and certification requirements. Standard configurations generally have shorter production cycles, while highly customized projects may require additional engineering and testing time.

How do you ensure product quality before shipment?

Our quality control covers material inspection, production process control, electrical testing and final inspection. Each customized solution is checked against the agreed technical specifications before shipment.
