Dual power automatic transfer switch designed for reliable, fast transfer between a normal power source and a backup source. Key benefits Immediate backup activation: When the normal power supply is abnormal, the backup power supply will work immediately to improve conversion rates, minimizing downtime. Flexible operation: Dual power automatic transfer switch can be operated automatically or manually to match site requirements and maintenance procedures. Easy installation and maintenance: Rail mounted design allows quick mounting on standard DIN rails and straightforward access for maintenance. Stable performance: Built for consistent switching performance in demanding environments. Technical specifications Size: 2P AC 110V Rated Voltage: 220V Rated working voltage: 230 AC Rated working current: 125 A Insulation voltage: 690V AC Mode: Dual power automatic transfer switch, automatic or manual operation Installation: Rail mounted, easy to install and maintain Function and compatibility Function: Monitors the normal power supply and automatically switches to the backup power supply when abnormalities occur, then switches back when normal supply is restored. Compatibility: Suitable for AC systems matching the listed rated and insulation voltages and the specified current rating. Use with appropriate upstream and downstream protective devices and wiring consistent with local electrical codes. Performance highlights Rated working current 125 A supports mediumload circuits. Insulation voltage 690V AC provides margin for common lowvoltage distribution applications. Dual operation mode gives operators manual control for testing and service without disabling automatic protection. Typical applications Industrial factory power distribution: automatic switching for production lines, machine tools, or control panels to reduce production interruptions. Laboratories and testing facilities: maintain continuous power for test equipment and instruments during supply disturbances. Agricultural and farm installations: switch utility power to backup generators for irrigation pumps, processing equipment, and refrigeration systems. Installation notes Rail mounted for standard electrical cabinets and control panels. Ensure wiring and upstream protection match the rated working current and voltages before commissioning. This transfer switch provides a practical, railmounted solution for automatic and manual power source transfer where stable, reliable switching is required.
