Genset Power Controller ATS220 Item Type: Genset Power Controller Model: ATS220 Material: ABS Purpose: Power Switch Control Display: 4digit LED Overview The ATS220 is a panelmounted genset automatic switching controller designed for reliable transfer between mains and generator power. It uses a clear 4digit LED display to show voltage and frequency, and allows direct setting of all parameters via frontpanel keys. Builtin simulation of mains and flexible start conditions make the controller suitable for a wide range of backup power applications. Panel sealing rings provide IP54 level protection after installation. Key benefits Automatic transfer and generator control: Controls switching between mains and generator and manages generator start and shutdown timing. Flexible, useradjustable settings: All timing, trip, and alarm values are adjustable to match site requirements. Clear status and measurement display: 4digit LED display shows mains and generator voltage and frequency, plus status indicators for quick diagnostics. Durable panel design: ABS enclosure with standard sealing rings provides IP54 protection after panel installation. Simple operation: Parameters are set directly from the panel using intuitive keys, reducing setup time.

When the load is switched to mains, the display automatically shows mains voltage. Mains Frequency Indication: Shows mains frequency when selected. Power Generation Voltage Indication: Shows generator voltage on the display. When the load is switched to generator, the display automatically shows generator voltage. Generating Frequency Indication: Shows generator frequency when selected. Mains Status Indication: Indicator stays on when mains is normal, flashes for lowvoltage and voltage alarms, and is off when mains power is absent. Mains Closing Instruction: Lights when mains closing command is active. Power Generation Status Indicator: Stays on when generator output is present. Applications and typical use cases Commercial backup power: Automatic transfer and generator control for small to medium commercial buildings to maintain critical services during mains loss. Industrial equipment protection: Manage reliable switching and generator start/stop sequences for production lines, compressors, or pumps. Remote sites and telecom: Provide automatic generator control and clear status feedback where unattended operation and robust enclosure are required. Installation and operation notes Panelmounted design with standard sealing rings; IP54 protection for the panel after installation. All parameters are configurable through the frontpanel keys. No external programming tools required. Compatible with standard single and threephase genset control arrangements where timed start, stop, and transfer control are needed. The ATS220 provides configurable, transparent control of power switching between mains and generator sources, with clear LED readouts and panellevel protection suitable for a variety of backup power installations.
