The RDS3 Series PC Class Automatic Transfer Switch is a space-saving solution designed for commercial and industrial applications requiring reliable power transfer in limited environments.
Space-Optimized Design:
30% smaller than standard switches (width 200-600mm), fitting into narrow electrical cabinets (300mm depth), ideal for retrofitting older installations.
Stackable modular design, supporting up to 3-phase configurations (100-800A) without additional spacing, reducing cabinet volume by 40%.
Precision Control Technology:
Microprocessor-based auto-transfer with adjustable time delays (0.1-30 seconds), preventing nuisance tripping during transient voltage fluctuations.
Soft-transfer technology for inductive loads, reducing inrush current by 30% compared to standard mechanical switches.
Integrated Monitoring:
Built-in LED indicators for power source status, fault conditions, and transfer history (last 50 events), with optional RS485 communication for remote diagnostics.
Voltage/current logging (1-minute intervals), downloadable via USB for power quality analysis (IEEE 519 compliance).
Reliability & Safety:
Double-break contactor design (UL 1008 Listed), ensuring positive isolation of non-energized sources, with mechanical life ≥150,000 cycles.
IP54 protection (NEMA 12) for indoor use, with optional IP66 for outdoor cabinets in dusty/moist environments.
Perfect for space-constrained setups, the RDS3 Series is used in:
Retail & Hospitality: Powers POS systems, refrigeration, and lighting in malls and hotels, ensuring continuous operation during grid outages.
Small Data Centers: Provides N+1 redundancy for edge computing nodes and server closets, compliant with Uptime Institute Tier II standards.
Industrial Substations: Supports distribution transformers and switchgear in compact substations, with IEC 61850 communication for smart grid integration.
Marine Vessels: Installs in engine rooms and bridge consoles, with marine-grade coatings (ISO 12944 C5-M) for saltwater resistance.
Q: What is the minimum clearance required for installation?
A: Only 50mm front access for maintenance, suitable for tight spaces behind walls or under floors.
Q: Can it handle three-phase to single-phase loads?
A: Yes, built-in phase conversion technology supports mixed load configurations with automatic neutral current balancing.
Q: Does the compact design affect heat dissipation?
A: No, optimized heat sinks and airflow channels maintain contactor temperature ≤70°C at full load, validated via CFD simulations.
