In fast-moving industrial environments, even brief power interruptions can cause extensive damage—resulting in lost production, damaged equipment, and tarnished reputations. Minimise downtime is vital to maintaining continuous operations, and achieving a stable power supply in industrial settings is the core solution. At United Automation, our power control products are specifically designed to prevent downtime by ensuring reliable, smooth power delivery across your operations.

What Are Power Control Products for Downtime Prevention?
Power control products regulate and stabilise electrical power to equipment, protecting systems from interruptions, voltage surges, and transient events. Our range includes:
- Thyristor Controllers for smooth voltage regulation and protection
- Soft Start Controllers to reduce startup inrush and mechanical stress
- AC Voltage Regulators for maintaining constant voltage levels
- Power Line Filters to eliminate EMI that can trip sensitive systems
By managing power flow and isolating issues, these products greatly reduce the risk of unexpected shutdowns.
How Do Power Control Products Minimise Downtime?
1. Smooth Start and Load Management
Soft Start Controllers like the SSC-25 PLUS gently ramp up power to motors, pumps, and heaters—preventing starter overloads that can trip circuits or wear out mechanical components.
2. Voltage Regulation
Voltage fluctuations are a common cause of equipment failure. Our AC Voltage Regulators provide a stable power supply, reducing electrical stress and improving equipment lifespan.
