Basic, terminal type, network type dual power automatic switching device Product Overview With the development of society, dual power switch price, people power supply reliability requirements are also increasing. Many occasions with two-way power supply to ensure reliability of supply, which requires a two-way power between reliable switching device to ensure stable power supply. Dual power automatic switching device is to meet this requirement and the development of a proprietary product. Plastic breaker / miniature circuit breakers (CB-class) and load switch (PC level) is complete disconnect between the power supply and the load and turn the actuator. The product has automatic recovery and not from the vote since the complex two switching functions, for the three-phase voltage three-phase four-wire power supply simultaneous detection of two-way power, when any one phase overvoltage, undervoltage (including phase ), which automatically switches from normal to abnormal power supply; for power - power systems products can emit signal generation and unloaded, and therefore a perfect performance, secure, reliable, high degree of automation, using a wide range of dual power automatic switch products. Dual power automatic switching device is suitable for AC 50Hz, 400V two-way power (common power supply and backup power supply or power supply), when a power failure and all the way to automatically switch between the power supply to ensure the reliability and safety of the product performance should be consistent with the provisions of national standards on electromagnetic compatibility (EMC) Terms of GB / T14048.11-2002 basic, terminal type, network type dual power automatic switching device products have common characteristics: 1. automatic recovery: 2. Since the vote of no self-recovery: 3. Power - generator :( optional) according to the actual situation dual power switch engineering plant, the production levels of ATS PC to ST dual power switch ATS switch, for example, we do in order to brief elaborated: 1. Dual power automatic transfer switch controller with the same period of the phase capture. Switching from the normal side to the standby side power supply, and switching from the standby power supply to the normal side of the power supply side are equipped with the same period of the phase capture function, the controller automatically detect simultaneously two power voltage, phase and frequency. Ensure that equipment in the two-way power waveform almost identical circumstances dual power switch vendors, and instantly switch is complete. To the safe operation of equipment to bring great benefits. 2. ATS dual power switch power off ms conversion time is level, use a large amps dual power automatic transfer switch, power conversion time dual power switch, including the controller detects a power failure, the controller drives the switch contacts head, three times the synthesis switch contact action. 3. Dual power switch with great Icw rated short-time withstand current levels. Far greater than the circuit breaker rated short time withstand current levels. This ensures that a large current flows through the circuit breaker and automatic transfer switch, automatic transfer switch will not be in the circuit breaker tripped, ensuring the reliability of power supply load, continuity. 4. A dual power switch with N lines overlap conversion function that switches the N line to install a changeover contacts, N line using before-break function. . 5. dual power switch in the switch body coil electromagnetic drive internal use, mechanical locking. Very reliable power supply to avoid the two side by side issues. . 6. dual power switch in the contact portion of the switch body with silver-tungsten alloy, good to meet the conductivity and temperature requirements, at the same time also have a special arc chute to ensure that the moving contact and static contact separation When the switch is complete arcing inside the switch. 7. dual power switch with self vote of no self-recovery and automatic recovery functions, fully meet the GB GB14048.11-2002 in dual power switch wholesale, double-Electric (certified), dual power switch from Shanghai only Thailand Industrial Co., Ltd. Yueqing Branch provided. Shanghai only Thai Industrial Co., Ltd. Yueqing Branch (www.cnats.cc) is Wenzhou, Zhejiang Province, switch leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
