Mini ATS Automatic Transfer Switch Dual Power Switch Uninterrupted Power Din Rail Type(4Pole 25A AC220V)

- When the normal power is abnormal, the spare power works at once. - When the normal power supply is normal, it will automatically switch back from the backup power to the normal power supply. - We don't guarantee completely uninterrupted, but minimizing issues from power interruptions. - This automatic transfer switch is suitable for the emergency power supply system with 50 or 60 Hz. Specially designed for household orbit-type installation and specially use in PZ30 power distribution box. - The backup power supply is suitable for AC power. If the AC power supply through DC inverter is used, the voltage protector needs to be connected.

Product description

NOTE:

1. Manual/automatic operation can ensure the opening and closing performance of electrical operation, but in manual operation , cannot be assured due to the different opening/closing speeds of the operators. In manual operation, there's possible for excessive silver alloy loss . Therefore, the selector switch should only be pulled to the manual position after all power has been cut off for inspection and maintenance of the operating system and contact information.

2. Normally, pull the selector switch to the electric position. When manual operation is required, pull the selector switch to the manual position. After manual operation is complete, pull the selector switch from the manual position to the automatic position. The control circuit TSE is immediately energized. After the change over is completed, the internal switch will damage the coil in the control circuit, and the coil can work normally at 85%-110% of the rated operating voltage. Too low input voltage may cause the coil to overheat and burn out. Attention!When manual operation the mode selection switch must be in "manual" position.

This automatic transfer switch is a PC class infrequent change-over switch, with two-station design (commonly used for A and standby for B), suitable for AC systems with AC 50-60hz and rated current 6A-63A. The main function of the automatic transfer switch is when the main power (common power supply A) fails, the ATS will automatically switch to the backup power (Backup power supply B) to continue working (switching speed <50 milliseconds), which can effectively solve the troubles caused by power outages.

When both A and B have electricity, priority is using A Power
