Industrial Voltage Stabilisers and Power Conditioning Equipment Watford Control / Watford Control Instruments
We supply industrial electromechanical and solid-state voltage stabilisers, power conditioners, and dynamic voltage sag compensators manufactured by British specialist Watford Control / Watford Control Instruments. Custom engineering and equipment supply for manufacturing plants, data centers, and mission-critical power networks worldwide.
Electromechanical Voltage Stabilisers EMS and EM Series
Watford Control EMS and EM electromechanical voltage stabilisers provide continuous protection for industrial power supplies. Proprietary Twin Track Rotavolt technology ensures smooth regulation with 0.5% accuracy up to 4000 kVA. We supply servomotors, carbon brushes, and transformers.
- Power ratings from 1 kVA up to 4000 kVA in single or three-phase setups
- Proprietary Twin Track Rotavolt technology with correction range up to ±40%
- Output voltage accuracy maintained within 0.5% across heavy industrial loads
- Class II transient surge protection and integrated digital power metering
Solid-State Static Stabilisers Infinity and Infinity+
Watford Control Infinity and Infinity+ solid-state stabilisers operate without moving mechanical parts using transductor technology. They deliver ultra-fast correction in under 3 ms with up to 0.3% True RMS accuracy. Maintenance-free operation makes them ideal for demanding ambient sites.
- Ultra-fast correction response time under 3 ms with 0.3% True RMS accuracy
- Solid-state transductor technology without moving parts or wear components
- High-power Infinity+ series up to 3200 kVA with correction ranges up to ±50%
- True fit-and-forget maintenance-free operation with over 10-year design life
Dynamic Voltage Sag Compensators Oxygen Series
Watford Control Oxygen dynamic voltage compensators eliminate deep grid voltage sags of up to 50% in under 5 ms. They safeguard variable speed drives, CNC machine tools, and automated robotic lines from unplanned shutdowns. Modular systems support capacities up to 4000 kVA.
- Sub-cycle voltage sag compensation up to 50% within less than one mains cycle
- Ultra-fast response under 5 ms preventing inverter trip and line stoppage
- Comprehensive power handling from compact units up to 4000 kVA installations
- Engineered for semiconductor fabs, robotic packaging, and imaging medical suites
Power Conditioners and Isolation Transformers
Watford Control power conditioners integrate precision voltage stabilization with deep attenuation of transient spikes and harmonic interference. Built-in isolation transformers with secondary neutral-to-earth bonding eliminate common-mode noise for clean instrumentation power.
- Robust attenuation of voltage spikes and transient disturbances up to 6 kV
- Integral isolation transformer reducing common-mode noise to absolute zero
- Limits residual neutral-to-earth interference voltage to below 0.25 V peak
- Flexible enclosure options from chassis IP00 up to weatherproof IP54 enclosures
Industrial High-Power Electromechanical Voltage Stabilisers up to 4000 kVA
Watford Control EMS series three-phase AC voltage stabilisers deliver robust centralized grid protection for heavy manufacturing facilities, mining sites, and processing complexes.
Proprietary Twin Track Rotavolt technology enables smooth phase-independent regulation without waveform distortion at an accuracy of 0.5%.
Transductor-Based Solid-State Static Stabilisation Technology Infinity
Precision Infinity series stabilisers are engineered for facilities demanding ultra-pure power quality.
The complete absence of moving carbon brushes and in-line power semiconductors delivers a sub-3 ms correction response, exceptional surge tolerance, and field operational lifespans exceeding 50 years.
Sub-Cycle Voltage Sag Protection for Critical Automated Plant with Oxygen
High-speed Watford Control Oxygen dynamic voltage compensators eliminate grid voltage sags of up to 50% in less than 5 milliseconds. This eliminates nuisance tripping of variable speed drives, automated robotic surface-mount lines, data center servers, and multi-axis CNC machine centers.
Galvanic Isolation and Clean Mains Conditioning via Power Conditioners
Watford Control line conditioners equipped with ultra-isolation transformers eliminate common-mode noise, high-frequency transients, and high-energy voltage surges down to a safe threshold below 0.25 V peak.
The units supply clean, spike-free power to mission-critical analytical instrumentation and laboratories.
