Features PREMIUM FIREPROOF MATERIAL - Using fireproof plastic material, good insulation, high temperature resistance, safe and reliable. HOW IT WORKS When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity of the power supply. Practical Accessory - Silver contacts are used for movement and static, which greatly improves the conductivity and service life of the product. Purpose: Switch to backup power supply when power fails, and switch to main power supply when power arrives. Good working performance: Built-in normally standby opening signal output port, which can be connected to the signal indicator. Small size, easy to carry and store, convenient to use and with good performance. Specification: Model No.: ZGQ5-100/2P Material: plastic. Working frequency: 50-60HZ Rated current: 100A Rated Voltage: AC110-230V Working voltage: AC220V Operating mode: Automatic and manual ATS: CB level Conversion time: ≤0.05(S) Number of Poles: 2P How to use: 1. Place the dual power supply automatic transfer switch on the debugging platform 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 incorrectly. 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 auto turn and auto reset 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. Configure the common power supply NA, NB, NC, NN for any phase failure, the dual power supply should automatically become the backup power supply, if the common power supply returns to normal, it must be converted back into common power supply. 5. Adjust the voltage of any phase of the common power supply to the default low voltage value, and the dual power supply should automatically switch to the backup power supply. When the normal power supply returns to normal, the switch should return to the normal power supply.
