Brief description
Factory machine tools, hospital CT machines, and 5G base stations can all use it to prevent voltage fluctuations. Mobile phones can also monitor remotely. Its durability is 5 times that of traditional voltage stabilizers.
Features
1. Ultra low energy consumption ‌
Contactless three phase 380v regulator Energy conversion efficiency ‌≥98%‌, only 2 degrees of electricity is wasted for 100 degrees of electricity, which saves half of the electricity compared to traditional voltage stabilizers.
2. IIndestructible ‌
3. Silent operation ‌
No mechanical carbon brush friction sound, as quiet as a “library” when working, suitable for hospitals and laboratories.
4. Remote monitoring ‌

Applications
1. Shipbuilding factory ‌
The “anti shake hand” of the dock gantry crane can lift a 100 ton ship without shaking even when the voltage fluctuates violently.
2. Construction site ‌
“Energy stabilizer” for tower cranes and concrete pump trucks to avoid the risk of high altitude operations caused by unstable voltage.
3. Commercial complexes ‌
The “constant temperature switch” of the central air conditioner in the shopping mall ensures that the air conditioning supply is not interrupted during the peak electricity consumption in summer.
4. Scientific research particle accelerator ‌
Product details

Wear free design ‌
Traditional voltage stabilizers use carbon brushes to adjust the voltage, which will wear out over time; the contactless type uses ‌electronic induction technology‌, which adjusts the voltage like “wireless charging”, with a lifespan of more than 10 years and almost no maintenance!

Refer to the specification table for verified ratings and available options.
Model, electrical ratings and options are listed in the specification table.

Wide voltage adaptability ‌
Contactless three phase 380v regulator The input voltage ‌285V-475V‌ can stably output 380V, even if the power grid fluctuates like a “roller coaster”, the equipment can operate safely
FAQ
Q: Contactless three phase 380v regulator Does it require manual operation to restart after a power outage?
A: Fully automatic recovery design, automatically detects and outputs stable voltage within 3 seconds after a call comes in, as worry free as a “smart socket”.
Q: Will the output have electromagnetic interference?
A: 95mm² copper core cable (current carrying capacity ≈ 250A) is recommended, which is like building a “two way six lane” for the current.‌

Professinal Package
Lithium batteries are DG goods. The shipping must according to MSDS and UN38.3 regulations. Coremax lithium batteries have passed all required rules. All batteries packed with foams in a brown carton box. Then fit into wood case or wooden pallet. The packing materials provide strong protections to inside batteries. Make sure customer receive batteries in a best condition.
How to ship lithium battery packs.
- 1. For small lithium batteries cells and small battery packs, we can ship by air or express.
- 2. For heavy shipment and higher wh/ batteries, we will shipping by freight. For large order, we ship by containers.
- 3. Coremax provides standard shipping to most area like USA and Europe. Shipping service include DDU. DDP. Please confirm with our sales team for the latest shipping rate.
Lithium ion batteries are different from normal shipment. It requires special shipping forwarder to take care of them. You are welcome to use your shipping agent. Before that, please confirm with your agent as these are DG shipment. We provide shipping service to most area and different country. As battery weight and detail address will cause a different shipping rate. Please contact us for the exactly shipping cost on your order.
