Automatic Phase Selector – 100A, 3-Phase + Neutral, Digital Control

The Tronic CO APS5-100 Automatic Phase Selector is a smart changeover switch designed to ensure stable power supply in 3-phase systems by automatically selecting the best available phase based on user-defined voltage thresholds. It features a digital LCD display, customizable settings, and protection against overvoltage, undervoltage, and overcurrent. This DIN-rail mounted device is ideal for residential, commercial, and light industrial setups that require seamless and reliable power transfer between phases.
