The RDS3 Series PC Class Automatic Transfer Switch is a heavy-duty solution designed for high-current industrial applications, ensuring reliable power transfer in manufacturing plants, data centers, and large-scale infrastructure. Engineered with robust contactors and advanced synchronization technology, this switch handles demanding loads while maintaining precision control over power sources.
Industrial-Grade Performance:
Supports 200-4000A (600V AC), with optional bus bar configurations for parallel operation, ideal for motor control centers and switchgear lineups.
Rapid transfer time (≤100ms) with phase-angle matching, minimizing torque fluctuations in large induction motors (≥500HP).
Enhanced Protection Features:
Built-in overcurrent protection (5-10x rated load) and under-voltage detection (±10% tolerance), compliant with IEC 60947-6-1 Type A/B standards.
Thermal imaging sensors (accuracy ±2°C) monitor contactor temperature, triggering alerts before overload damage occurs.
Modular Design:
Plug-and-play contactor modules (3-phase/1-phase) for easy replacement, reducing downtime during maintenance by 70%.
Customizable terminal blocks (copper/aluminum) for utility, generator, and load connections, supporting cable sizes up to 1000kcmil.
Environmental Adaptability:
IP65-rated enclosure (NEMA 4X) for harsh environments (dust, water jets), with optional conformal coating for coastal salt exposure.
Wide voltage input range (180-528V AC), accommodating unstable grid conditions in emerging markets.
Critical for heavy industrial power systems, the RDS3 Series is used in:
Power Plants: Transfers loads between grid and backup generators in thermal, hydro, and nuclear facilities, compliant with NERC CIP standards.
Mining Operations: Powers conveyor belts, crushers, and ventilation systems in underground mines, with explosion-proof enclosures (ATEX Zone 2) available.
Data Centers (Large Scale): Supports 4000A+ load banks in hyperscale facilities, integrating with automatic load balancing for N+1 redundancy.
Transportation Hubs: Ensures uninterrupted power for railway signaling, airport baggage systems, and tunnel ventilation, meeting EN 50155 railway standards.
Q: What is the maximum short-circuit current rating?
A: 100kA at 480V AC (ICCW rating), with bolted pressure contacts for superior fault current handling.
Q: Can it be used in DC power systems?
A: Standard models for AC systems; custom DC versions (12V-1000V) available with silicon-controlled rectifier (SCR) technology.
Q: How is the switch tested for reliability?
A: Undergoes 10,000 cycle load testing, salt spray (1000 hours), and voltage sag simulation (IEEE 1668), ensuring compliance with IEC 61000-4-11.
