The UST SagFighter™ is an industrial-grade, solid state, electronic voltage sag corrector, or active voltage conditioner, that operates without batteries or energy storage.
Industrial-grade means the SagFighter is compatible with all non-regenerative load types and load power factors and provides a minimum 1,000% fault-clearing capability. Unlike computer-grade products or uninterruptible power supplies (UPS), the SagFighter is designed for frequent high-inrush current and low-power factor loads without the need to oversize the product.
- Sag protection compliant with SEMI-F47
- Full sag correction within 2 milliseconds
- Sag correction duration independent of load or power factor
- Sag correction for a minimum of 100 seconds
- No need for bypass operation for high inrush or overload currents
- Continuous protection without the need to recharge or reset
- Non-continuous inverter operation that increases reliability and provides 99% efficiency
- Battery-free design
- Applications with voltage sensitivity that are subject to irregular mains supply voltage.
