ABB ATS021 – Automatic Transfer Switch Controller
The ABB ATS021 is an Automatic Transfer Switch (ATS) controller designed to manage the seamless transfer between two power sources, such as a primary utility line and an emergency generator or backup line. It ensures continuous power supply by monitoring voltage and frequency parameters and automatically switching to the alternate source when anomalies are detected.
🔧 Key Features
Dual Power Source Monitoring: Continuously monitors both primary (LN1) and secondary (LN2) power lines for voltage and frequency irregularities.
Automatic and Manual Modes: Offers both automatic switching based on predefined parameters and manual control via front panel buttons.
Configurable Parameters: Adjustable voltage thresholds (±10%, ±15%, ±20%, ±30%) and time delays (TS, TBS, TGOFF) to suit specific application needs.
LED Indicators: Front panel LEDs provide real-time status of power lines, circuit breakers, operational mode, and alarms.
Test Functions: Built-in test modes allow simulation of transfer scenarios to verify system functionality without actual power source interruption.
Compact Design: DIN rail or door-mounted installation options facilitate integration into various control panels.
