Dual Power Automatic Transfer Switch Currency Interrupter ZGQ5-100/4P 220V Feature:1. The use of silver contacts can greatly improve the conductivity and service life of the product2. Built-in standby open signal output port, which can be connected with a signal light, which is convenient for observation outside the cabinet3. The use of high-quality fireproof plastic, good insulation, high temperature resistance, anti-aging, safe and reliable4. When the normal power supply is abnormal, the backup power supply will operate immediately to ensure the continuity, reliability, and safety of the power supply5. Suitable for switching to backup power when the power is cut off, and switching to the main power supply when the power comes inSpecification:Item Type: Dual Power Automatic Transfer SwitchModel: ZGQ5-100/4P Material: PlasticPurpose: Switch to backup power when power fails, and switch to the main power supply when power appearsOperating frequency: 50-60HZrated current: 100A Rated voltage: AC110-230V Voltage Working: AC220VThe working mode: automatic and manualATS: CB levelConversion time: le; 0.05 (S)Number of poles: 4PSpuses of use:1. Place the automatic transfer switch double power supply on the debug platform, and connect the corresponding power line according to the correct phase sequence. The phase line and the neutral line are connected in the position, and the wrong connection is not allowed.3. When debugging the three-pole switch, the common and backup neutral wires should be properly connected to the neutral terminal (LV and RN).3. Set the automatic dual power transfer switch to work in self-rotating and 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. Set the common power supply NA, NB, NC, NN for each phase loss, double power should be automatically converted TO backup power supply, if the common power supply returns to normal, it should be converted back to common power supply5. Adjust the voltage of any common-power phase to a certain undervoltage voltage value, and the dual power supply should automatically switch to standby power. When the normal power supply returns to normal, the switch should return to normal power Packing List:1 x Dual Power Automatic Transfer Switch1 x User Manual
