Thy Speed -TSC-M
Thy Speed -TSC-M
Thy Speed -TSC-M Thyristor Switch is a compact, solid-state thyristor switching module engineered for ultra-fast ( < 10 ms) capacitor switching in dynamic Power Factor Correction (PFC)systems. Utilizing zero-current/voltage switching logic, it eliminates transients and inrush currents, making it ideal for applications with rapidly fluctuating reactive loads such as welding, cranes, and VFD systems. Available in 25–100 kVAr ratings with 24V DC or 230V AC control input options, it features integrated RC snubber, NTC-based thermal protection, multicolour LED diagnostics, and fan-assisted cooling. Designed for seamless integration into APFC panels, it ensures long service life, silent operation, and full compliance with IEC standards.
Our Product Features
Ultra-Fast Switching ( <10 ms)
Enables dynamic PFC applications by switching capacitors in less than one-half cycle, suitable for loads with rapidly changing reactive power.
Zero-Current/Voltage Switching Logic
Synchronizes capacitor switching at zero-crossing to eliminate transients and inrush currents.
Robust Design
Easily integrates into new or existing capacitor banks or APFC panels.
Dual Control Options
Available with either 24V DC or 230V AC control input, compatible with most APFC relays.
Built-in Protection Features
Includes RC snubber circuit, NTC-based thermal protection, and LED fault indicators.
Ease of Installation
Clearly marked terminals, pre-wired modules, and DIN rail or backplate mounting.
Status Indication & Diagnostics
Multicolour LED indicators for power, capacitor status, temperature, and faults.
Long Operating Life & Silent Operation
Solid-state design eliminates mechanical wear and noise.
Safety & Standards Compliance
Designed per IEC standards; requires external fuse protection.
