Model and size: ATS220 Overview The ATS220 is an electronic engine control designed for automatic transfer switch applications between mains power and a single phase genset. It supports both automatic and manual modes, provides clear status and measurement readouts, and allows full parameter configuration from the front panel or a PC port. Key benefits Reliable source transfer: Controls ATS operation in auto or manual mode to streamline switching between mains and generator power. Clear system visibility: Four digit LED display shows generator voltage, generator frequency, mains voltage, and mains frequency for fast diagnosis. Status LEDs indicate ATS switch position and operating state. Easy configuration: Set and adjust all parameters using front face buttons or through the PC port for convenient commissioning and maintenance. Compact and practical: Single unit controller sized ATS220 for straightforward installation into standard ATS panels or control enclosures. Reduced downtime: Faster, clearer transfer decisions and easy setup help minimize interruption during power events. Main functions and attributes Function: Automatic transfer switch control with auto and manual selection. Monitoring: 4 digit LED tube for single phase voltage and frequency display for both mains and genset. Indication: LED indicators for ATS switch working status. Configuration: Front panel buttons and PC port for parameter programming and adjustments. Compatibility: Designed for use with single phase mains and generator power systems; intended for integration with ATS hardware. Size: ATS220 controller format suitable for ATS system panels. Use scenarios Emergency backup for small commercial buildings: Automatically switch to generator power when mains fail and to mains when restored. Remote generator installations: Monitor generator and mains voltage and frequency while configuring settings via the PC port during commissioning. Industrial or agricultural sites with single phase backup: Provide clear status indicators and simple manual override when site personnel need direct control. The ATS220 provides focused ATS control and monitoring in a compact, configurable package suitable for single phase mains and generator transfer applications.
