ATS220 Single Phase Genset ATS Controller Overview The ATS220 is a dedicated single phase ATS controller for automatic or manual transfer between mains and generator power. It displays voltage and frequency for both mains and generator, shows ATS switch status with LEDs, and lets you configure all parameters from front panel buttons or via a PC port. Compact and robust, the ATS220 integrates control, monitoring, and switching outputs needed for reliable single phase genset automatic transfer applications. Key benefits Automatic and manual transfer control for seamless mains to generator switching. Clear, immediate status and measurements: 4digit LED display shows mains voltage, mains frequency, gens voltage, and gens frequency while LEDs indicate ATS switch status. Flexible installation and compatibility: wide DC supply range and universal AC inputs support a variety of single phase genset and mains systems. Simple configuration: set parameters directly from the front panel or remotely through the PC port. Compact footprint for panelmounted applications. Main features 32unit microprocessing technology is used. Wide DC operating range: DC 8 to 36 V continuous. 4digit LED display for voltage and frequency readouts. Seven relay outputs with maximum switching current 5 A at AC 250 V. One programmable switch input group. Parameters adjustable by front face buttons or PC connection. Standard waterproof rubber seal, protection level IP54. Technical specifications Operation voltage: DC 836 V continuous Power consumption: standby (24 V): max 1 W; working (24 V): max 3 W Mains AC voltage input: 30 VAC to 300 VAC (phase to neutral) Gens AC voltage input: 30 VAC to 300 VAC (phase to neutral) Gens close output: 5 A (AC 250 V) contact Mains close output: 5 A (AC 250 V) contact Gen start relay: 5 A (AC 250 V) contact Total relay outputs: 7, maximum 5 A each (AC 250 V) Programmable switch input: 1 group Display: 4digit LED and LED indicators for ATS status Dimensions: 78 mm x 78 mm x 55 mm Practical applications Backup power automation for small commercial buildings where single phase mains and a genset are used. Remote sites and telecom cabinets that require automatic transfer and status monitoring with compact control hardware. Construction or temporary power installations where a simple, reliable ATS controller manages generator start and transfer. Compatibility and installation notes Designed for single phase mains and genset systems with phasetoneutral voltages within 30 to 300 VAC. Requires DC supply between 8 and 36 V for controller operation. Mounts in a standard panel cutout with a compact 78 mm by 78 mm face and 55 mm depth. All relay outputs are contacts rated for 5 A at AC 250 V; confirm these ratings meet your switching load requirements. The ATS220 provides straightforward automatic transfer control, clear monitoring, and flexible configuration for single phase genset installations, packaged in a compact, panelready controller.
