从China供应商批量进口Industrial Three Phase Electromagnetic Contactl

Output low-voltage / High-voltage protection Built-in low-voltage / high-voltage detection and protection circuit. Protection points adjustable. When output voltage is out of range, protector will cut off output and give warning (LED Blinking). Open-phase protection Built-in Open-phase protection circuit. When Open-phase happens, protector will cut off output and give warning (LED Blinking). Overload protection Built-in overload protection will protect this AVR automatically even the output was short circuit. Superior monitoring system Even with the mentioned built-in protection inside, we integrated a Superior monitoring System to give double insurance of the performance. Soft-output function Built-in Soft-output function, when started or resume form power outages, output voltage will be started from a low voltage to avoid damage to equipments. Free form Voltage-Drop Dual-stack design. Even a single phase loading is imbalance up to 50%, Voltage-Drop will not happen. So it is ideal for motor, servo motor and other launch-frequent equipments. Pure Linear Voltage adjustment Linear Induction control, no voltage ladder. (Relay type and servo motor type can only give ladder voltage output) Electromagnectic Contactless design No contact surface in the machine, no Arc. Modular design Complete Modular design, for easy after sales services and debugging. Fully isolated, manual bypass function For maintenance or repairs, bypass can be activated manually (short-circuit and overload protection are still on guard). High temperature detection Built-in temperature detection circuit, when main coils are overheating LED blinking will be activated, giving message that maintenance or replacement of the mail coils required. Misoperation prevention design To prevent misoperation, double lock system was applied in this AVR. Only press the two power buttons in the same time can the machine be started or shut down. Excellent loading / overloading ability 100% load for continuous operation, transient inductive loading is also welcome. Seriously selected industrial-strength components, work for more than 10 years Lifespan can be more than 10 years. All components are selected for years, transient high voltage is welcome.
