2-Pole Automatic Transfer Switch (ATS) – For Single-Phase Critical Loads

Key Features & Benefits:

1. Seamless, Automatic Operation:

   • Feature: An integrated microprocessor controller constantly monitors voltage and frequency on the primary source. Upon detecting an outage or deviation beyond set parameters, it sends a start signal to the generator and executes the transfer once backup power is stable and within tolerance.

   • Benefit: Eliminates downtime for critical loads. The transition is fast enough to keep most sensitive electronics running without disruption, protecting data and processes.

2. Robust & Adaptive Control Logic:

   • Feature: Programmable time delays including engine start delay, transfer delay (to allow generator stabilization), and retransfer delay (to ensure utility power is stable). Features source priority selection (Utility or Generator preferred).

   • Benefit: Protects the generator from short-cycling and ensures clean, stable power is delivered to the load, extending equipment life for both the ATS and the generator.

3. High-Reliability Switching Component:

   • Feature: Utilizes a high-grade, electrically-held contactor or a zero-crossing solid-state relay as the switching element, designed for thousands of reliable operations under load.

   • Benefit: Provides dependable performance and long electrical life. The chosen mechanism ensures positive isolation between sources to prevent backfeed, a critical safety function.

4. Compact Design for Easy Integration:

   • Feature: Engineered with a space-optimized footprint, available in open-frame models for panel builders or in self-contained enclosures (NEMA 1 or 3R).

   • Benefit: Fits into tight spaces in electrical cabinets or on walls, simplifying installation in both new constructions and retrofit projects for critical circuits.

5. User-Friendly Interface & Diagnostics:

   • Feature: Front-panel interface with clear LED indicators for power source status and alarms. Includes a manual test switch to simulate an outage and verify system operation without disrupting the actual power.

   • Benefit: Simplifies testing and troubleshooting. Provides instant visual confirmation of system status, ensuring readiness and simplifying maintenance.

Technical Specifications:
