The RDS2 Series PC Class Automatic Transfer Switch is a premium solution designed for seamless power source transitions in mission-critical applications, ensuring uninterrupted power supply for data centers, hospitals, and industrial facilities. Engineered with advanced synchronization technology and robust construction, this switch minimizes downtime by rapidly transferring loads between primary and backup power sources, ideal for environments where power continuity is non-negotiable.
Precision Power Transfer:
Ultra-fast transfer time (≤80ms) with phase synchronization, preventing voltage spikes and equipment damage during utility-to-generator transitions.
PC Class (Power Conditioning) rating for non-interruptible load transfer, compliant with UL 1008 and IEC 60947-6-1 standards.
Dual Power Inputs:
Supports 240V/480V AC inputs (50/60Hz), with load capacity ranging 100-2000A, accommodating both single-phase and three-phase applications.
Automatic source prioritization (utility first, then generator/ESS), with manual override for emergency control.
Intelligent Monitoring:
Built-in microprocessor with LCD display, real-time monitoring of voltage, current, and transfer status, supporting Modbus RTU/TCP and BACnet for IoT integration.
Predictive maintenance alerts for contactor wear (≥100,000 operations) and thermal overload (130°C trip point).
Safety & Compliance:
Mechanical interlock and electrical interlock for zero parallel operation, meeting NEC 705 and IEC 61439-1 safety standards.
IP54-rated enclosure (NEMA 3R) for indoor/outdoor use, with optional IP66 for harsh environments (salt spray resistance ≥500 hours).
Ideal for critical power systems, the RDS2 Series excels in:
Data Centers: Ensures uninterrupted power for server racks and cooling systems during utility outages, supporting Tier III/IV redundancy requirements.
Hospitals & Healthcare: Maintains power to MRI machines, OR equipment, and life support systems, compliant with NFPA 99 and Joint Commission standards.
Industrial Manufacturing: Powers CNC machines, robotics, and control panels in factories, reducing production downtime from power fluctuations.
Renewable Energy Grids: Integrates with solar/wind inverters and battery storage, enabling smooth transition between grid and off-grid power sources.
Q: What is the difference between PC Class and CB Class switches?
A: PC Class switches (RDS2) are designed for non-interruptible transfer without breaking the circuit, ideal for sensitive electronics, while CB Class (RDQ3) uses circuit breakers for higher fault protection.
Q: Can this switch handle inductive loads?
A: Yes, built-in surge suppression handles motor starting currents (6x rated load) without tripping, suitable for pumps, compressors, and HVAC systems.
Q: Is remote monitoring available?
A: Yes, optional WiFi/GPRS modules enable real-time status tracking via mobile app, with email alerts for critical events (power loss, transfer cycle).
