Uninterrupted Power Switching.

TOMZN 3P AC ATS Features

• Automatic Dual-Power Switching – Automatically transfers load between two AC power sources (e.g., grid and backup/inverter) without manual intervention, ensuring uninterrupted power when one source fails.

• 3-Phase Compatibility (3P) – Designed for three-phase systems (uses a 3-pole or 4-pole configuration for loads requiring three phases), adaptable for 63 A, 100 A, or 125 A rated currents.

• Fast Switching (< 50 ms) – Quickly switches sources in less than 50 milliseconds, minimizing power interruption to connected equipment.

• PC-Level Reliability – Built to PC (Programmable Controller) level standards for dependable automatic switching and protection of appliances and circuits.

• Surge Withstand Voltage (8 kV) – High impulse voltage resistance helps protect the ATS and connected loads from voltage spikes (e.g., lightning or transient surges).

• Wide Voltage Operating Range – Works reliably within approx 85 %–110 % of rated supply voltage, adapting to minor grid or generator fluctuations.

• Automatic & Stable Operation – Detects supply failures and switches without user action, providing stable and continuous power for three-phase electrical equipment.

• DIN-Rail Mountable – Standard DIN rail design for easy installation in distribution panels and electrical enclosures.

• Durable Mechanical and Electrical Life – Designed for repeated automatic switching with long mechanical and electrical cycle life (typically thousands of operations).
