【FLAME-RETARDANT PLASTIC MATERIAL】: The automatic transfer switch is made of flame-retardant plastic material, with good insulation, high temperature resistance, and reliable. Small size, easy to carry and store, easy to use, good performance. 【PROTECTION FUNCTION】: The dual power switch controller supports multiple functions, including short circuit, overload, phase loss, under voltage protection, etc. When the normal power supply is abnormal, the backup power supply works immediately to ensure the continuity of the power supply. When the normal power supply is on, it will automatically switch back to normal power supply from the standby power supply. 【EASY TO USE】: Family transfer switch silver contacts for motion and static electricity, which greatly improves the conductivity and service life of the product. Built-in standing open output port, which can be connected with indicator. 【TWO MODES】: Automatic switch not only supports automatic mode, but also can be operated by manual button, easy to operate and performance. 【SPECIFICATIONS】: 50-60HZ working frequency; 100A rated current; AC110-230V rated voltage; AC220V working voltage; two modes of operation, automatic and manual.

How to Use: 

1. Place the automatic transfer switch of the dual power supply on the debugging , and connect the corresponding power line in the correct phase sequence. The phase line and the neutral line are connected in position and cannot be connected wrongly.

2. When debugging the three-pole switch, the common and spare neutral wires should be connected to the neutral terminal (NN and RN) respectively.

3. Set the dual-power automatic transfer switch to work in the self-turning and self-resetting mode. If the voltage of the two power supplies is normal, the switch should be placed in the common power supply position and the common power supply is closed.

4. Set the common power supply NA, NB, NC, NN for any phase failure, the dual power supply should be automatically converted to the backup power supply, if the common power supply returns to normal, it should be converted back to the common power supply.

5. Adjust the voltage of any phase of the common power supply to the predetermined undervoltage voltage value, and the dual power supply should automatically switch to the standby power supply. When the normal power supply returns to normal, the switch should return to the normal power supply.
