Electric Power Stabilizer
Built for Real Factory Power
Wenzhou Mingyue Electric Co., Ltd. manufactures the Electric Power Stabilizer in Liushi Town, Yueqing, Zhejiang. The company was established in 2019 and has been operating for 7 years.
Our 1,000-square-meter facility has 20 skilled workers and an in-house R&D team. We comply with local environmental requirements and test voltage and current on every unit before shipment.
A 100% inspection is completed before packing. If a unit is damaged during transport, we repair or remake it at our factory. The product is supplied with a 5-year warranty.
Three-Phase Control You Can Trust
This unit uses three-phase unified compensation technology. The standard input voltage is 380V ± 20%, covering a range of 304V to 456V. For grids with wider voltage fluctuations, a ±30% input range is available as a customization option.
The rated output current is approximately 228A, with a stable output voltage of 380V. The unit uses a three-phase four-wire configuration, with a phase voltage of 220V. Standard voltage accuracy is ±3%, while ±1% accuracy is available for applications with higher voltage stability requirements.
The response time is no more than 1 second, and overall efficiency is above 98%. The unit does not introduce additional waveform distortion, helping maintain stable power for downstream precision equipment. Protection functions include overvoltage, undervoltage, phase loss, phase sequence, overload, and short circuit protection. It also features power-on delay start and a motor carbon brush compensation structure.
The cabinet is made of cold-rolled steel and includes an LCD screen and clear status indicators. The operating temperature range is -5°C to +40°C. For installations above 1,000 m, derating is required. The unit complies with the JB/T7620 standard and is suitable for factory power distribution, building power systems, and machinery applications.
OEM Support and Full Data
We support OEM and ODM services. The MOQ is 30 units, and different models or colors can be mixed in one order. Custom samples take about one week to develop. Both standard and customized products can be produced in about one week.
The Electric Power Stabilizer is available with different input ranges, voltage accuracy levels, and export frequency options to meet different project requirements.
