Color: Ats320ac Model Number: ATS320 Product overview A compact automatic transfer switch controller that combines metering and control functions with clear LCD and LED displays. Designed for single phase two wire power systems, it monitors operating status and fault conditions while controlling transfer between generator and mains power. Housings are made of ABS for durability. Key benefits Integrated metering and control: LCD and LED displays provide real time monitoring, operating status, fault indication, and metering in one unit. Wide input voltage range: Accepts AC 90V to 450V to work reliably with varying supply conditions. Low power consumption: Standby power consumption MAX 1W and working power consumption MAX 2W reduces auxiliary load. Long accumulation and logging capability: MAX accumulating time 99999.9 Hours with minimum store time 6 min for long term runtime records. Safe, noncontact outputs: Separate generator and mains closing outputs are noncontact normally open relays rated 250V/5 AMP for reliable switching without mechanical wear. Durable construction: ABS material for stable performance and long service life.

Use with single phase mains and single phase generator supplies. Noncontact normally open outputs are intended to drive external contactors or relay inputs rated to match the 250V/5 AMP specification. Typical use scenarios 1) Residential standby generator control: Monitor generator run time, display fault conditions, and automatically transfer load between mains and a single phase backup generator. 2) Small commercial or retail power backup: Centralize metering and transfer control for a single phase supply feeding essential equipment, with logged accumulating time for maintenance planning. 3) Remote equipment or telecom shelters: Provide compact transfer control and status indication where low auxiliary power consumption and long runtime logging are required. What to expect in operation Clear LCD and LED indications for live monitoring of voltages, operating status, and faults. Automatic transfer control using noncontact outputs to operate external contactors. Longterm recording of run time up to 99999.9 Hours with a minimum store interval of 6 minutes. Ordering information Model Number ATS320 Color code Ats320ac Note: Ensure compatibility with your generator and mains wiring configuration before installation. Follow applicable electrical codes and use appropriately rated external contactors when switching higher currents.
