Our Product Features
Fast and Reliable Switching
Uses zero-crossing switching technology to connect/disconnect capacitor banks at the optimal point in the voltage waveform. Ensures virtually transient-free switching, preventing high inrush currents and extending capacitor life. Capacitor switching operations are performed within 0-10 ms for ON and 0-20 ms for OFF, ensuring real-time compensation.
High Duty Performance
Rated for capacitor duty, meaning it can handle the high inrush and peak currents typically associated with capacitor switching. Supports frequent operations, ideal for dynamic power factor correction in rapidly changing loads.
Integrated Protection Features
Equipped with RC snubber circuits and MOV-based surge protection. Inbuilt fuse or circuit breaker provision for overcurrent and fault protection.
Capacitor Current Monitoring
Real-time measurement and display of current in each phase (R, Y, B) and average value.
Protection & Fault Monitoring
Comprehensive protections including over-current, under-current, earth fault, dv/dt disturbances, SCR short, and over-temperature.
Auxiliary Outputs
Provides two potential-free N.O. contacts for external fault signalling: one for heat-sink over-temp and one for SCR short.
Robust Design
This thyristor switch is engineered for long-term performance in industrial APFC applications.Designed to handle rapid switching under varying load conditions, it supports multiple configuration options—including single-pole, 3-pole, and banked arrangements—making it adaptable to diverse system requirements. Its robust construction ensures high durability and dependable operation in challenging electrical environments, ideal for both new installations and retrofit projects.
LED Indication and Diagnostics
Provides LED status indicators for each phase and fault conditions. Simple visual diagnostics help in maintenance and fault identification.
Low Power Loss and Heat Generation
Utilizes efficient thyristors with low on-state voltage drop. Reduced power loss translates into minimal heat dissipation and lower cooling requirements.
High Electrical Life
No mechanical contacts ensure millions of switching cycles without mechanical wear. Ideal for high-reliability applications in commercial and industrial installations.
Customization Options
Current ratings and control voltage options can be customized based on application. Available in multiple voltage and current configurations.
