Meiji Indonesia Food Manufacturing Facility with 1000KVA Voltage Stabilizer System
Introduction
This project introduces the 1000KVA industrial voltage stabilizer provided by Winzele for the Meiji Indonesia food manufacturing facility. After the production base expanded and new equipment was put into operation, the original power supply system showed voltage variation during different production periods. Through on-site assessment by the local installation contractor, a 1000KVA voltage stabilization solution was confirmed, using a series-connected voltage stabilizer integrated into the existing power supply line to provide a stable voltage environment for production equipment.
As an application of a factory voltage stabilizer at an overseas food manufacturing base, the capacity requirement was specified by the Japanese customer, and the local installation contractor completed the power supply condition assessment at the Karawang site and assisted in equipment installation and commissioning.

Capacity determination process:
Customer Project Requirements ↓ Local Installation Contractor Site Assessment ↓ Existing Power System Evaluation ↓ 1000KVA Solution Confirmation
The capacity solution is based on actual project requirements and on-site conditions.
Power Challenge
All-Day Voltage Fluctuation After Expansion
The original power supply system was designed for the early production requirements. After expansion, new production equipment and automated machinery were added, increasing load differences across different time periods:
- Daytime production periods: After equipment is in operation, current demand increases and input voltage drops;
- Nighttime periods: Production load decreases and voltage rises.
The daytime drop and nighttime rise create all-day input voltage fluctuation, affecting the operation stability of production equipment and automated equipment.
This is a common voltage problem after factory expansion. Similar voltage fluctuation problems are common in expanded manufacturing facilities, continuous production factories and automated production lines.
Solution Provided
1000KVA Series-connected Voltage Stabilization System
Winzele adopted a series-connected voltage stabilization solution, integrating a 1000KVA industrial voltage stabilizer into the existing power supply system without replacing the original electrical infrastructure.
- The original line was disconnected;
- The stabilizer was connected in series;
- The stabilized output is maintained at 380V, supplying production equipment.
Without replacing the original grid structure, the stabilization system improves the production power supply environment and increases voltage consistency under different production conditions. The on-site requirement is that the stabilized output is maintained at 380V, meeting the operating requirements of production equipment.

FAQ
Q: Why does the factory experience different voltage levels during day and night after expansion? A: The original power supply system was designed for early production requirements. After expansion, new production equipment and automation loads were added. During daytime operation, current demand increases and input voltage drops; at night, production load decreases and voltage rises, creating all-day input voltage fluctuation.
Q: What does series connection mean? A: Series connection means connecting the stabilizer into the existing power supply line: the original line is disconnected and the stabilizer is connected in, and the stabilized output then supplies production equipment. This improves the power supply environment without replacing the grid.
Q: Why was a 1000KVA stabilizer selected? A: The capacity for this project was proposed by the customer and confirmed through local installation contractor site assessment, based on the production base’s power supply system and load conditions.
Q: How to select the right voltage stabilizer capacity for a factory? A: Industrial voltage stabilizer capacity generally needs to be determined considering transformer capacity, production load characteristics, starting current, on-site voltage conditions and power distribution system structure. The 1000KVA capacity in this project was proposed by the customer and confirmed through local installation contractor site assessment. A food manufacturing voltage stabilizer selection also needs to combine production load characteristics and on-site power supply conditions.
Q: Is this project applicable to overseas food manufacturing factories? A: Similar solutions apply to industrial scenarios that need improved voltage stability, such as expanded manufacturing bases, food processing plants and continuous production factories.
