High-frequency resonant soft-switching technology optimized for UK Power Networks, National Grid compliance, and heavy industrial applications.
Heavy-duty 10kW system designed for centralized UK grid substations and primary distribution automation.
Engineered with dual-pole earth fault isolation systems, matching BS 7671 standards for switchgear backups.
Equipped with high-level TCP/IP & SNMP protocol interfaces for automated SCADA monitoring networks.
Ultra-compact 1U configuration allowing easy hot-swap operation in modern UK telecommunication nodes.
The UK industrial and power distribution landscape is marked by strict reliability standards. 110VDC systems are the cornerstone of substation safety, serving as the auxiliary power system for control cabinets, protection relay boards, and breaker tripping systems. In England, Scotland, Wales, and Northern Ireland, Network Operators (DNOs) mandate dual-pole isolated 110V DC battery charger networks to guarantee control power remains uninterruptible during primary grid shut-downs.
Our rectifiers are specifically tuned to align with UK grid dynamics. In an era where renewable energy integrations—such as offshore wind farms along the North Sea and large-scale solar arrays in the south—require robust and stable grid connections, EVS rectifiers provide the necessary DC stability to maintain communication channels and operation controls without interruption.
Our rectifiers utilize cutting-edge digital control technology to provide superior energy density and long-term operating efficiency.
Legacy linear thyristor-based power systems are rapidly giving way to modern high-frequency Switch Mode Rectifiers (SMRs) globally, particularly in developed European and North American markets.
Characterized by bulky, low-frequency copper transformers, poor input power factor (typically 0.7 to 0.8), high heat generation, and low response times (>100ms) to load transients. These units demand heavy maintenance and large footprints in industrial environments.
Leveraging high-frequency resonant soft-switching technology (LLC), our rectifiers operate at switching frequencies above 100kHz, allowing up to 95.8% efficiency, active power factor correction (PFC > 0.99), response times <5ms, and small dimensions.
Equipped with microprocessors that run DSP algorithms, allowing communication via MODBUS RTU, CAN, and SNMP. They enable remote asset management, predictive diagnostic logging, and automatic thermal foldback protection.
In the United Kingdom, infrastructure owners are retrofitting old power cabinets with modular rack-mount rectifiers to optimize space, minimize heat loading in sealed enclosures, and align substation equipment with modern cyber-security and SCADA communication protocols.
Tailored solutions for utility distribution networks, specialized DC distribution systems, and telecom base stations across Britain.
Robust 100A output for large-scale utility battery banks. Features automatic load-sharing when operating in parallel configurations.
A highly stable 3000W module featuring deep current limiting protections, suitable for dynamic industrial inductive loads.
Specially engineered for hydroelectric facilities and distributed telecom networks requiring wide input voltage ranges.
A highly versatile module offering broad AC grid compatibility, suitable for deployment in remote UK cellular towers.
Combining advanced production methods with strict quality standards to deliver cost-effective and reliable power solutions globally.

Our power systems are engineered to withstand demanding environments in both urban facilities and remote utility locations.
Providing essential auxiliary DC power for high-voltage and medium-voltage switchgear. In a grid failure, our rectifiers and battery systems supply the critical tripping currents required to open circuit breakers and protect downstream infrastructure.
Compliant with rail isolation rules, EVS rectifiers provide reliable 110VDC outputs for trackside signalling systems and points control, maintaining operations during AC power interruptions.
Designed for compact 1U/2U server cabinets. High power density configurations operate with 95%+ efficiency, reducing thermal load and cooling costs in UK data hubs.
Providing stable DC control power for heavy machinery, automated processing plants, and critical valve actuators in water treatment works where control failure is not an option.
