About this Item
Silver contacts are used to greatly improve the conductivity and service life of the product.Built-in signal output port for standing brake, can be connected to signal indicator, easy to observe outside the cabinet.Made of high quality flame retardant plastic, good insulation, high temperature resistance, anti-aging, safe and reliable.When the normal power supply is abnormal, the backup power supply will work immediately, thus ensuring the continuity, reliability and safety of the power supply.Product ParameterCommodity parametersName: Dual power automatic transfer switchModel: ZGQ5-100/4PMaterial: plasticUse: transfer to standby power supply when power failure, transfer to main power supply when incoming power.Frequency: 50-60HZRated current: 100ARated voltage: AC110-230VWorking voltage: AC220VOperation mode: automatic and manualATS: CB levelConversion time: ≤0.05 (S)Number of poles: 4PUsagePlace the dual power automatic transfer switch on the debugging table, connect the corresponding power lines according to the correct phase sequence, and butt the phase line and neutral line (zero line) according to the position, so as not to connect the wrong one.When debugging the three-pole switch, the common and standby zero wires should be connected to the zero terminal (NN and RN) respectively.Set the dual power automatic transfer switch in the self-initiation and self-recovery mode. If the voltage of the two power supplies is normal, the switch should be placed in the position of the common power supply, and the common power supply should be closed.Set any phase of common power supply NA, NB, NC, NN to break, the dual power supply should be automatically converted to standby power, and if the common power supply returns to normal, it should be converted back to the common power supply.V. Adjust the voltage of any phase of the common power supply to a predetermined undervoltage value, and the dual power supply shall automatically switch to the standby power supply. When the common power supply returns to normal, the switch should return to the common power supply.Operating instructionsPacking listDual power automatic transfer switch *1Instruction manual*1
