Feixiangda Power Empowers Nigerian Ice Plant to Overcome Chronic Low-Voltage Challenge
SBW Servo Voltage Stabilizer + Step-Up Transformer Combination Solution Wins High Customer Satisfaction
SHENZHEN, China — Shenzhen Feixiangda Electronics Co., Ltd. (Feixiangda Power) has successfully delivered a customized voltage stabilization solution for an ice-making plant in Delta State, Nigeria. The plant operates nine refrigeration compressors on a three-phase supply, but the local grid has long suffered from severe voltage sags — dropping to 170–255 V during peak hours. Feixiangda's engineering team designed a combined system pairing an SBW series servo voltage stabilizer with a step-up transformer, holding the output steady at three-phase 400 V ±2 %. The result: compressors start reliably, ice production is back to full capacity, and the customer reports a sharp drop in equipment maintenance costs.
01 Customer Background & Pain Points
The ice plant is located in Delta State, Nigeria, and operates nine refrigeration compressors — all three-phase (400 V) loads — on a three-phase mains supply. However, the local power grid has long been unreliable, creating a set of challenges that are representative of industrial users across West Africa:
Severe undervoltage: During daytime and evening peak hours, grid voltage drops to 170–255 V — far below the level required to start compressors. Refrigeration cycles are interrupted and ice output drops dramatically.
Prolonged duration: The undervoltage is not a brief, occasional event — it often persists for several hours at a time, causing sustained disruption to production.
Accelerated equipment wear: Repeated start failures and prolonged low-voltage operation inflict irreversible damage on compressor motors, driving up repair and replacement costs.
No overvoltage concern: The customer confirmed that serious overvoltage is virtually absent in the area — the core challenge lies entirely on the low-voltage side.
These problems are highly representative of Nigeria and the broader West African region. Many industrial users face a similar predicament: weak grid infrastructure, voltage sags during peak demand, and precision or heavy-duty equipment that simply cannot operate — severely constraining business operations.
02 The Solution
After a detailed assessment of the customer's actual power environment, Feixiangda's engineering team designed a tailored combination solution:

03 Design Highlights
Wide-Input Design, Tackling Undervoltage Head-On: The SBW servo stabilizer features an ultra-wide input range. Paired with the step-up transformer, it maintains a stable 400 V ±2 % output even when input voltage drops to 170–270 V. This is critical for African low-voltage regions, where most conventional stabilizers simply shut down below their minimum input threshold.

This is critical for African low-voltage regions, where most conventional stabilizers simply shut down below their minimum input threshold.
Servo-Mechanical Regulation for Industrial Reliability: Unlike electronic stabilizers, the SBW uses a mechanical carbon-brush regulation mechanism. It delivers high load capacity, tolerates sustained heavy-duty operation, and is ideally suited for ice-plant applications that demand continuous high-load performance.
Modular Layout for Flexible Expansion: The customer adopted a modular approach — one stabilizer per ice tank, serving two compressors each. This allows phased deployment within budget constraints and eliminates the risk of a single-point failure bringing the entire plant to a halt.
Premium Imported Components: All critical stabilizer components — from servo motors to carbon brushes and contactors — are sourced from top-tier international brands, ensuring long-term operational stability and reducing maintenance frequency and downtime risk.
04 Results & Customer Feedback
After the solution was deployed, the customer reported the following outcomes:
Compressors start smoothly — even during peak-hour voltage sags, the stabilizer output remains within 400 V ±2 %, and the refrigeration system has not experienced a single low-voltage-induced shutdown.
Ice production has returned to normal levels, and equipment maintenance frequency has decreased noticeably.
The customer expressed overall satisfaction with the solution and plans to equip the remaining ice tanks with stabilizers as budget permits.
